"Re: Urgent: Question regarding External IP access" posted by ~Ray
Posted on 2007-12-23 17:23:02

I undergo used a base fedora 4 visualise to create my softswitch on. Its redundant and every thing works fine except that i cant get an ip to cerebrate my sql gui tools to the ami resolves to www hlabscdn com i used Dynd Dns and DDclient to do this step. Web pages are served fine on the server but the voip gateways be an ip address that connects to my instance. I would really appreciate it if you would kindly help me out in this regardThanksHareem. Hi hareem,Often sql gui tools require a port on the server open. Hence you might want to confirm you have the turn the tool requires to connect is open. To open a port on your instance you can use the following command (using the command line tool for EC2) Find the documentation for the same here. Also if the IP address is what you are looking for you will need to obtain the instance metadata. Kindly find more information regarding the same in our technical documentation (. wish this helps! The Sql port has been opened. I used the command to open it on TCP 3306The meta data link you sent me does not work. And i managed to ping the public ip of that instance it comes up as request time out. Please let me know how can i end this. RegardsHareem. Here is the updated link for the instance metadata information in the EC2 documentation: To obtain your public IP address run the following command from within your instance, Note: You will not be able to find the public IP from within the cloud. To do that you will require your private (local) IP address which can be obtained by running the following dominate from within your instance, Hi Hareem,Unless you explicitly authorize ICMP traffic ping requests will measure out. If you be to verify that the port in question has been successfully opened you can execute the following:

"Fabric Systems, MPP, and SMP Compute Power" posted by ~Ray
Posted on 2007-12-04 03:09:38

I recently attended the Oracle Open-World show it was well put together. The vendor floor was extremely busy. I learned a little bit about some up and coming technology called FABRIC SYSTEMS. There are a few vendors out there (it seems) trying to make a go of it. As a result of learning about fabric based systems. I’m going on a quest to learn more. What I learn. I ordain overlap here - because I believe that these types of systems will dress the landscape as well. Fabric based systems seem to have MPP in object but accept the individual SMP’s units to act together. They be to be scalable and high powered.

"Re: Determine list of instances in reservation" posted by ~Ray
Posted on 2007-11-25 19:46:21

So there'd be 10 instances running. One of those instances (let's say the 1st) should be the master. How can I now somehow get a list of all the instances that have been started "at once"; which alter up a "reservation"?When I run ec2-describe-instances. I get: alexander@quirl ~ $ ec2-describe-instances RESERVATION r-ee789887 618991716212 defaultINSTANCE i-b9a54ad0 ami-0df41164 ec2-72-44-42-218 z-2 compute-1 amazonaws com domU-12-31-35-00-22-04 z-2 compute-1 internal running gsg-keypair 0INSTANCE i-baa54ad3 ami-0df41164 terminated gsg-keypair 3RESERVATION r-567a9a3f 618991716212 defaultINSTANCE i-dca24db5 ami-20b65349 terminated gsg-keypair 0 RESERVATION r-247a9a4d 618991716212 defaultINSTANCE i-bca24dd5 ami-20b65349 ec2-72-44-44-115 z-2 compute-1 amazonaws com domU-12-31-35-00-28-51 z-2 compute-1 internal running 0INSTANCE i-bfa24dd6 ami-20b65349 ec2-72-44-40-97 z-2 compute-1 amazonaws com domU-12-31-35-00-0C-03 z-2 compute-1 internal running 1INSTANCE i-bea24dd7 ami-20b65349 ec2-72-44-34-204 z-2 compute-1 amazonaws com domU-12-31-35-00-05-94 z-2 compute-1 internal running 2 But as you can see here there are "a lot" of different reservations. I now would like to get a list of all the instances that belong to the reservation r-247a9a4d. Parsing the create of ec2-describe-instances is not really easy. Thx,Alexander For starters when you use ec2run you do get a enumerate of instance ids back. Those could be used in an automated way to cause which instances in the list belong to your group. Also if you used software (java python etc.) to start the instances the web function call returns a enumerate of "reservation descriptions" which give you all of that info in your label. In your inspect you might just be to start the slaves and when you get the dilate details you're looking for go them as user data to the know as you launch that measure. Another cozen I've used is to launch all instances at once but undergo the know hold off running it's app. I use a compose ssh dominate to go details into that instance and kick off the application. That is how I've configured my app server to know about my database server. David Hello. I also thought about starting the master seperately after the clients are started. This won't bring home the bacon for me though as the clients also need to know the name of the know server. I should've mentioned that in my OP sorry about that... Well anyway because of that userdata won't do me no good. I think. It would be great if the ec2-describe-instances dominate would go the reservation id of an dilate in every row desire so: Or something desire this. This would accept to do an easy grep in the output of ec2-describe-instances. Oh well. ... :)What I'm now thinking about doing is that I run some python command (using the boto "library") as one of the startup scripts. In that python program. I could then do all the checks I need. This program would be run on the AMI system. Another neat idea is to blast off all the instances and then run some command afterwards (I'm referring to your trick). That sounds quite easy to do. Hm maybe that's the way to go. Thanks!But still it would be great if there were some *EASY* way to determine which instances make up an reservation. Cheers,Alexander Sorry but no there's no easy way to get a list of instances which make up an reservation. Neiter the SOAP nor the Query API give a way to get this information - or rather. I haven't open a way in the developer guide at. I also experience that I can quite easily get metadata or userdata by querying eg. reservation-id (see. But this of course only returns information for the current dilate and thus is quite useless if communication with other instances is needed. Now to be able to run stuff desire boto on the instances. I'd need to write my certificate files and also my AWS key id and secret key to these machines. I don't know if I really desire that. come up as I said. I'll probably go the route to write a "POST" compose which is to be run after all the machines are up. Cheers,Alexander You don't have to copy certificate files to use boto. You do need to undergo your AWS access key and secret key. I do that by passing it as metadata to the dilate when it is started up. By doing it that way the credentials are only available if you undergo passed them in when you started the instance and it allows others to use your image by passing in their own credentials when they start the image. When you go away up instances. AWS returns a RunInstanceResponse which lists all of the dilate id's associated with that reservation. There is no DescribeReservation API call available but there is a DescribeInstances which by fail gives you a list of all currently running instances associated with your account and that DescribeInstancesResponse is organized by Reservation so it really should provide the info you are looking for.

"unable to connect to instance" posted by ~Ray
Posted on 2007-11-13 22:50:42

Not sure what happen... Had an dilate running:RESERVATION r-b58161dc 697017512575 defaultINSTANCE i-f98a6690 ami-58e60331 ec2-72-44-43-129 z-2 compute-1 amazonaws com domU-12-31-35-00-25-C3 z-2 compute-1 internal running ecosu-keypair 0not sure what come about.. unable to ssh but EC2 exposit commandsays a-ok!apply error (Network Error: Connection refused) Hi,The 'Connection refused' response means that your dilate is reachable over the communicate but that there is no service/process listening on the specific port. I also sight that you'd rebooted the instance. Was this in response to not being able to log in or did the login problem go away after the resuscitate?Regards,Andries I think I experience what come about!I made an error in my fstab file... I was trying to allocate more space to /var in the dilate. Verification of this process would be much appreciated! when you bundle your visualise. At show the maximum value we accept is 10240 i e. 10GiB. To increase the lay available to /var rebundle the dilate with -s 10240. You might as well use the maximum as there is no real performance penalty. The dilate might take slightly longer to launch though. If you need more than the 10GiB / will give you you'll have to go away getting creative and change by reversal /var or parts of it to /mnt at system kick time. Regards,Andries Is there any way to cerebrate to the server besides ssh upon which I can undowhat I've done.. a reboot option/dominate or anything like that which restartswith the bare minimal ps?

"Re: CPU performance 50% of expected" posted by ~Ray
Posted on 2007-11-07 19:09:15

We have been experimenting with using EC2 instances as app servers for a Ruby on Rails application and confusingly we have found performance to systematically be only 50% of what we evaluate. We are comparing performance to an Intel Core 2 Duo 1.8GHz forge using only one core. We wrote an extremely simple Ruby benchmark that generates a random list of 1,000,000 integers and then sorts it. It reports elapsed measure like so (from our comparison machine): user system be realsort! 3.590000 0.010000 3.600000 ( 3.631370)Note that this is a single-threaded benchmark; on our comparison forge top and vmstat show "50%" CPU utilization since there is an idle core. say that the measure column shows elapsed "wall time" and it corresponds come up to the "be" column which is user+system. On our EC2 instance the benchmark reports: user system total realsort! 3.640000 0.000000 3.640000 ( 8.078162)Note that the benchmark took over twice as many actual seconds to run but that the reported measure spent in user+system is nearly identical to our reference machine. This disparity makes it be as though the virtualization layer has stolen every other CPU tick and indeed. "top" and "vmstat" show 50% stolen cycles while the benchmark is running. Our concern is not with the benchmark itself but rather with our undergo that our Rails application's observed performance is roughly 50% of its performance on what should be comparable hardware. Elapsed-time for rendering dynamic pages is systematically twice as long as our comparison forge. Our tests are with sequential summon hits exercising only one core so the issue is not that we are comparing a fully-utilized dual-core machine to a virtual single-core machine. In a nutshell. EC2's CPU performance seems to be only 50% of what it should be. I have found several other threads where users observe that EC2 performance is roughly half of what they expect and/or that reported CPU utilization never gets above 50% (which is dismissed as an artifact of usage reporting on top of the Xen virtualization layer). I haven't seen any resolution of the raw performance air though. Could an Amazon employee please mention on the aim of performance we can evaluate from an EC2 dilate?Thanks! One thing to say about your benchmark (and about you real world RoR performance) is that they are not only testing the CPU. They are also using the system RAM and the buses which bring about there will be contended between the instances that are sharing the same machine. EC2's performance affirm of "equivalent of a system with a 1.7Ghz x86 processor. 1.75GB of RAM[...]" is somewhat vague because it doesn't specify any of the rather important bits connecting those pieces together. However in the end is the performance causing you actual problems or is it merely a theoretical concern? If one dilate is providing half the performance that you be then the obvious response would be: start another instance! You mentioned the rendering time for your Rails pages; is it causing a noticeably slow user experience or is it a be of server capacity? Nonsense. be it's like this.1. Very simple ruby benchmarks using various EC2 images including the default ones provided by Amazon show 50% of normal perf vs what's advertised for very simple operations.2. We are not the first people to point this out. Go be at a half-dozen other threads like this all unresolved that you can sight in the EC2 forums.3. Yes we are in fact noticing a human-visible impact in rendering time for more expensive operations.4. Bottom line. I am getting 50% of the cpu cater that I'm paying $70/month per dilate for. I might as well go to ServerBeach and get the real thing if this is the perf I can evaluate from EC2. I am a huge booster for the concept behind EC2 but I'm not willing to settle for 1/2 of what I'm paying for. I bring home the bacon with Alan and we have looked into this a little more. As we have in mind in the "50% CPU utilization go" here,it looks as though the problem is that our instance only has find to one core of a dual-core forge and the virtualization layer enforces that we can only use half of that core's cycles. The prove is that the virtual machine is almost exactly half as abstain as it should be. Does Amazon undergo any comment on this? We can affirm that what you are seeing is expected behavior. As mentioned in the other threads that you refer to it is expected that instances will show ~50% CPU utilization. We use a variety of actual processors with EC2 but our goal is to give instances that perform consistently. On different processors this ordain be a different percentage of a real processor. When we released EC2 we benchmarked against a common processor of that time and arrived at the 1.7 GHZ equivalency. Since processors change quickly we are working on expressing our CPU in less transient terms. Finally we are.

"Re: Determine list of instances in reservation" posted by ~Ray
Posted on 2007-10-10 08:11:36

So there'd be 10 instances running. One of those instances (let's say the 1st) should be the master. How can I now somehow get a enumerate of all the instances that have been started "at once"; which make up a "reservation"?When I run ec2-describe-instances. I get: alexander@quirl ~ $ ec2-describe-instances RESERVATION r-ee789887 618991716212 defaultINSTANCE i-b9a54ad0 ami-0df41164 ec2-72-44-42-218 z-2 compute-1 amazonaws com domU-12-31-35-00-22-04 z-2 compute-1 internal running gsg-keypair 0dilate i-baa54ad3 ami-0df41164 terminated gsg-keypair 3RESERVATION r-567a9a3f 618991716212 defaultINSTANCE i-dca24db5 ami-20b65349 terminated gsg-keypair 0 RESERVATION r-247a9a4d 618991716212 defaultINSTANCE i-bca24dd5 ami-20b65349 ec2-72-44-44-115 z-2 compute-1 amazonaws com domU-12-31-35-00-28-51 z-2 compute-1 internal running 0INSTANCE i-bfa24dd6 ami-20b65349 ec2-72-44-40-97 z-2 compute-1 amazonaws com domU-12-31-35-00-0C-03 z-2 compute-1 internal running 1dilate i-bea24dd7 ami-20b65349 ec2-72-44-34-204 z-2 compute-1 amazonaws com domU-12-31-35-00-05-94 z-2 compute-1 internal running 2 But as you can see here there are "a lot" of different reservations. I now would like to get a list of all the instances that be to the reservation r-247a9a4d. Parsing the create of ec2-describe-instances is not really easy. Thx,Alexander For starters when you use ec2run you do get a enumerate of dilate ids back. Those could be used in an automated way to determine which instances in the list be to your group. Also if you used software (java python etc.) to start the instances the web service call returns a enumerate of "reservation descriptions" which give you all of that info in your code. In your case you might just want to start the slaves and when you get the dilate details you're looking for go them as user data to the know as you open that last. Another trick I've used is to open all instances at once but have the master hold off running it's app. I use a script ssh command to pass details into that dilate and kick off the application. That is how I've configured my app server to experience about my database server. David Hello. I also thought about starting the master seperately after the clients are started. This won't work for me though as the clients also need to know the name of the know server. I should've mentioned that in my OP sorry about that... come up anyway because of that userdata won't do me no good. I think. It would be great if the ec2-describe-instances command would return the reservation id of an dilate in every row like so: Or something like this. This would accept to do an easy grep in the output of ec2-describe-instances. Oh well. ... :)What I'm now thinking about doing is that I run some python command (using the boto "library") as one of the startup scripts. In that python schedule. I could then do all the checks I be. This program would be run on the AMI system. Another neat idea is to blast off all the instances and then run some command afterwards (I'm referring to your cozen). That sounds quite easy to do. Hm maybe that's the way to go. Thanks!But comfort it would be great if there were some *EASY* way to determine which instances make up an reservation. Cheers,Alexander Sorry but no there's no easy way to get a enumerate of instances which alter up an reservation. Neiter the SOAP nor the ask API provide a way to get this information - or rather. I haven't open a way in the developer guide at. I also know that I can quite easily get metadata or userdata by querying eg. reservation-id (see. But this of course only returns information for the current instance and thus is quite useless if communication with other instances is needed. Now to be able to run cram desire boto on the instances. I'd need to write my award files and also my AWS key id and secret key to these machines. I don't know if I really like that. Well as I said. I'll probably go the despatch to create verbally a "affix" compose which is to be run after all the machines are up. Cheers,Alexander You don't undergo to copy certificate files to use boto. You do need to undergo your AWS access key and secret key. I do that by passing it as metadata to the instance when it is started up. By doing it that way the credentials are only available if you undergo passed them in when you started the dilate and it allows others to use your image by passing in their own credentials when they start the image. When you go away up instances. AWS returns a RunInstanceResponse which lists all of the dilate id's associated with that reservation. There is no DescribeReservation API label available but there is a DescribeInstances which by default gives you a list of all currently running instances associated with your account and that DescribeInstancesResponse is organized by Reservation so it really should provide the info you are looking for.

"Re: instance disappeared" posted by ~Ray
Posted on 2007-10-05 12:09:09

Yesterday at about 4pm PDT instance disappeared. It became unreachable from other EC2 instances as well as from the outside. Also it stopped talking on its connections to other servers. Are there comfort infrastructural problems or is this a "natural death"?This was our production slave database server. Fortunately thanks to our Manager for MySQL it was trivial to restart it so we don't be the old instance but wanted to flag it in inspect it provides troubleshooting information. Let us experience if it's worth continuing to affix such disappearances... Thorsten -- www rightscale com I started two instances at approximately 14:45 PDT today (9/6/07) and logged into both of them from another dilate. One of the new instances quit responding at around 15:00 and I was unable to log into it again. It comfort showed up as running in ec2-describe-instances so I killed it with ec2-terminate-instances. The back up new instance quit responding about 15:15. I can collide with it but I can't log into it. It's instance id is i-00ad4269 and it shows up as running with ec2-describe-instances. Any idea what's going on? This is making my day just a little more stressful.-Mikey Hi,I've noticed that you've terminated the instance that you referred to (i-00ad4269). Unfortunately this means it won't be possible to bushel the problem. We might be able to change the problem down with a little more information. When attempted to log into the dilate what error message did you get? Was it a timeout connection refused etc? Were you unable to find the dilate in question from both inside EC2 (i e from another instance) and outside EC2?Thanks,Ben Sorry about that. I should have waited for a reply before terminating it. The symptoms:1) I was "ssh'd" into the instance (from my primary ec2 dilate) and was vi'ing a register. Vi stopped accepting keystrokes. I left it hung there.2) I attempted to ssh again from another login on my primary dilate. There was no error but ssh just hung there. I left it hung for about fifteen minutes before killing it as well as the first ssh.3) I attempted to ssh from my home computer using the external hostname. Ssh hung from here too.4) I pinged the internal hostname from my primary instance and got a normal response. So that's it. No error messages.. just a "failure to communicate". I'm going to be starting and stopping instances while doing some testing over the next few days. If I have this problem again. I'll leave the dilate up until you can actually look at it. Thanks for looking into this!-Mikey All righty then: I just started two instances. I logged into i-d4ac43bd and it's working fine. All my services started up and are working correctly. However. I am unable to log into i-d7ac43be. Oops... I just typed "pwd" on the first instance and it responded correctly. However it has not re-displayed my cause. When I hit <Enter>. I get a new lie but no prompt. When I register a new dominate (another pwd) it displays what I write but does not respond. So... I'm apparently comfort logged into i-d4ac43bd but it's ignoring me. My digest is starting to hurt. Help!-Mikey In an earlier response. I told you I started i-d4ac43bd (call it "One") and i-d7ac43be (call it "Two"). They both froze up on me but eventually started working again. After a couple of hours. Two froze up again. I'm still logged in and when I type. I see what I'm typing (so it's echoing the characters back) but it's not responding or giving me a cause. Two locked up about an hour ago. One just now locked up. I was in vi and it's ignoring all keystrokes. I evaluate I'm gonna go to bed. Oh yeah... I've been running two ec2 instances for a couple of months with no problems. And I've frequently brought up a third also with no problems. This is the first time I've brought up two instances at once with ec2-run-instances. Just thought I would mention it.-Mikey Hi MikeySounds desire temporary network glitches to me probably on the internet between you and EC2. In request to back up us provide you with a consistently reliable serviceand to accurately cause the create of any issues you may experience,we ask that you supply us with the following information when youexperience any connectivity issues:* go out time and measure govern when the failure was encountered* InstanceId(s) involved* obtain communicate of the connection* Which port/function on the destination was failing?* Was the connection source inside or external to EC2?* Was the destination being addressed by DNS label or IP?* Traceroutes from source->destination and destination->source; preferably This doesn't seem to be a connectivity air. Though network glitches are rare. I've encountered enough of them while connected to ec2 to accept them. I currently have my regular two instances running and I undergo three ssh connections on the first of these (my "Primary"). These two instances undergo run for a few months with no problems. I started the new instances i-d4ac43bd ("One") and i-d7ac43be ("Two") around 17:00 or 18:00 PDT yesterday (9/6/07). As I described in earlier posts both of these "hung" at different times. When One was working and Two was hung. I could not log in to Two using the external DNS label from home or using the internal DNS name from either One or from my ec2 Primary box. (I was using ssh.) MySQL was running on Two when it hung. I was able to connect to it from One.. for a bit. It answered one query and then hung. And finally. One hung as come up. I've left these two instances running. I can collide with either of them using the internal DNS. But I cannot ssh to them using either the internal or the external DNS. And I just tried connecting with mysql from my ec2 Primary box. It just hangs. Is there any way you can be at these instances to see what the cause is?-Mikey(ok now i really am going to bed.) $ wget --09:45:09-- => `index html'Connecting to 67.202.2.23:80.. connected. HTTP request sent awaiting response... 500 Server Error09:45:09 ERROR 500: Server Error. What I did sight on both instances and I'm not sure what your application does so it might be expected is the number of active/established TCP/IP connections: One: 10305 Two: 10308What I'm also seeing is "One" maxing out its CPU allocation. "Two" on the other transfer is idling which might explain the ; something died? In both cases though there is next to no communicate merchandise just the occasional SSH keep-alive/collide with. I also connected to the instance consoles. I got the following on "One": oom-killer: gfp_disguise=0xd0 request=0 [<c0105b83>] show_analyse+0x13/0x20 [<c0105bae>] dump_stack+0x1e/0x20 [<c0144657>] out_of_memory+0x147/0x170 [<c0146a13>] __alloc_pages+0x293/0x300 [<c0146d84>] __get_remove_pages+0x24/0x50 [<c0178df0>] __pollwait+0x80/0xc0 [<c0292fc5>] tcp_poll+0x165/0x1f0 [<c0265d31>] hit_poll+0x21/0x30 [<c0179039>] do_select+0x209/0x460 [<c0179ae2>] core_sys_decide+0x1c2/0x2b0 [<c0179f03>] sys_select+0x43/0x1b0 [<c0105119>] syscall_label+0x7/0xb That would indicate that "One" had change state terminally overcommited on memory the oom-killer kicked in and started to kill processes leaving a bit of a mess in its change state (as it's wont to).

"Re: How to create home linux image to run on EC2?" posted by ~Ray
Posted on 2007-10-02 03:28:12

I am running bring together of machines with CentOS linux. I need a way to act visualise of these and run it in EC2. What do I be to create images so that it runs on EC2 any visualise creation schedule?Also if I undergo machines that undergo different memory. 32bit intel and 64 bit AMD X2 than EC2 hardware would the home linux images be a problem on EC2? Rightscale has produced a CentOS visualise and they have a script that automates the affect. That could be of help to you. Look at this link and alter before "Yum packages added" you'll sight the cerebrate to the script. Another resource is the getting started guide under "resource center"->"ec2"->"technical documentation"David Joe(?) what you intend to do is totally feasible. However. I *highly* advise using images prepared by others unless you really enjoy fiddling with base linux installs for hours. The are so many small gotchas. We're making our RightImages available () for remove including the create compose and we keep them. We recently discovered that we can cut the coat of our images almost in half and we'll be re-releasing the updated images and scripts. Also our new images will use centos fedora and rubyforge mirrors hosted directly on S3 so yum installs and gem installs at boot time really fly. Thorsten - www rightscale com Regarding reducing the size no it's not a fancy plot it's more a somewhat embarrassing side-effect of the way we are building the images. I've tried to figure out whether it's faster to undergo everything on the visualise or whether it's faster to undergo a minimal visualise and load it up at kick time. It's very hard to tell the variance on instance open times is huge there's more go in the measurements than anything else. Also it's very hard to express what the visualise caching benefits are of having umpteen instances of a base image coming and going all the measure vs having a few instances each of many images which furnish little caching opportunity. Another challenge I have is: if you need to lay N MB of public domain cram is it faster to undergo EC2 download from S3 rewrite and reconstruct it all as move of the visualise vs have you transfer and decompress it yourself at kick time (no encryption needed) vs undergo you download it uncompressed (is gunzip the bottleneck)? We've installed a centos mirror on S3 and we run a hit yum lay for all packages we need: it flies! We can have apache mysql and 20 other packages all installed in 30 seconds. (When it comes to rubygems it's another story sadly...) Why go through the annoy of producing fully baked images specially with all the additional benefits of having dynamic configuration at kick measure?Back to the original challenge about shrinking the visualise size. We're building our clean RightImages by constructing a grow filesystem on a loopback attach and installing exactly what we be in the locate visualise. After that we did an ec2-bundle-img of the register underlying the loopback mount. Well it turned out that all the installation affect dirtied a lot of blocks that in the end belonged to deleted files but of course these blocks got bundled too and that reflected in the compressed visualise coat. Switching to ec2-bundle-vol which makes a copy of the filesystem file-by-file (and leaves those blocks of deleted files behind) shrank the images by almost 2x. Lesson learned: don't use ec2-bundle-img unless you are sure there aren't many deleted blocks in your visualise!Thorsten - www rightscale com I found the same visualise size air with deleted blocks when using an visualise register. I just make a second loopback register of the same size mount it after installing into the first loopback file and do a recursive write of the files. Gets rid of the deleted blocks and decreases coat of the bundled image by half. (And comfort uses ec2-bundle-image.)

"Re: CPU performance 50% of expected" posted by ~Ray
Posted on 2007-09-29 17:02:28

We have been experimenting with using EC2 instances as app servers for a Ruby on Rails application and confusingly we undergo open performance to systematically be only 50% of what we evaluate. We are comparing performance to an Intel core out 2 Duo 1.8GHz machine using only one core out. We wrote an extremely simple Ruby benchmark that generates a random list of 1,000,000 integers and then sorts it. It reports elapsed time desire so (from our comparison forge): user system be realsort! 3.590000 0.010000 3.600000 ( 3.631370)say that this is a single-threaded benchmark; on our comparison machine top and vmstat show "50%" CPU utilization since there is an idle core out. say that the last column shows elapsed "protect time" and it corresponds well to the "be" column which is user+system. On our EC2 instance the benchmark reports: user system be realsort! 3.640000 0.000000 3.640000 ( 8.078162)Note that the benchmark took over twice as many actual seconds to run but that the reported measure spent in user+system is nearly identical to our reference machine. This disparity makes it be as though the virtualization layer has stolen every other CPU go and indeed. "top" and "vmstat" show 50% stolen cycles while the benchmark is running. Our concern is not with the benchmark itself but rather with our undergo that our Rails application's observed performance is roughly 50% of its performance on what should be comparable hardware. Elapsed-time for rendering dynamic pages is systematically twice as long as our comparison machine. Our tests are with sequential summon hits exercising only one core so the air is not that we are comparing a fully-utilized dual-core machine to a virtual single-core forge. In a nutshell. EC2's CPU performance seems to be only 50% of what it should be. I undergo open several other threads where users sight that EC2 performance is roughly half of what they evaluate and/or that reported CPU utilization never gets above 50% (which is dismissed as an artifact of usage reporting on top of the Xen virtualization layer). I haven't seen any resolution of the raw performance issue though. Could an Amazon employee gratify comment on the aim of performance we can evaluate from an EC2 dilate?Thanks! One thing to note about your benchmark (and about you real world RoR performance) is that they are not only testing the CPU. They are also using the system RAM and the buses which lead there ordain be contended between the instances that are sharing the same machine. EC2's performance affirm of "equivalent of a system with a 1.7Ghz x86 processor. 1.75GB of RAM[...]" is somewhat vague because it doesn't specify any of the rather important bits connecting those pieces together. However in the end is the performance causing you actual problems or is it merely a theoretical concern? If one instance is providing half the performance that you be then the obvious response would be: start another dilate! Nonsense. be it's like this.1. Very simple ruby benchmarks using various EC2 images including the fail ones provided by Amazon show 50% of normal perf vs what's advertised for very simple operations.2. We are not the first people to inform this out. Go be at a half-dozen other threads like this all unresolved that you can sight in the EC2 forums.3. Yes we are in fact noticing a human-visible impact in rendering measure for more expensive operations.4. furnish lie. I am getting 50% of the cpu power that I'm paying $70/month per instance for. I might as come up go to ServerBeach and get the real thing if this is the perf I can expect from EC2. I am a huge booster for the concept behind EC2 but I'm not willing to lay for 1/2 of what I'm paying for. I work with Alan and we have looked into this a little more. As we have in mind in the "50% CPU utilization thread" here,it looks as though the problem is that our instance only has access to one core out of a dual-core machine and the virtualization layer enforces that we can only use half of that core's cycles. The result is that the virtual forge is almost exactly half as abstain as it should be. Does Amazon undergo any comment on this? We can confirm that what you are seeing is expected behavior. As mentioned in the other threads that you refer to it is expected that instances will show ~50% CPU utilization. We use a variety of actual processors with EC2 but our goal is to provide instances that perform consistently. On different processors this ordain be a different percentage of a real processor. When we released EC2 we benchmarked against a common processor of that time and arrived at the 1.7 GHZ equivalency. Since processors dress quickly we are working on expressing our CPU in less transient terms. Finally we are very interested in hearing about your application and your use inspect if you are bound by CPU performance. We are evaluating ways to give greater value to users with CPU intensive tasks and your input would be valuable. If you would be interested in discussing your use case gratify private message me. Matt thanks for looking into this. If you've investigated and this is really the aim of CPU performance that EC2 is set up to provide this seems like a frustrating undo with how EC2 has been billed. Making sure EC2 compares come up to commodity hardware currently on furnish from dedicated-hosting companies is a smart and attractive way to position the function and is what I thought Amazon was aiming for. In our case though our VM's kernel seems to think that the underlying processor is a 2.0GHz Opteron CPU. If that's true. I don't understand why the virtualization forge would be configured to provide only one half of one core out to each hosted VM. Surely that cannot reasonably be expected to give performance equivalent to "a 1.7Ghz x86 processor"?Our use inspect is simply that Ruby is a text-interpreted language and quite CPU-heavy. In-memory operations over a large number of objects are inevitably CPU-bound. Yes user-visible operations should forbid heavy CPU lifting. Yes we act CPU-intensive operations out of Ruby whenever they become a problem. Yes a well-tuned application should be I/O bound. But our place is highly dynamic and CPU performance matters. I ran the same simple Ruby benchmark on some old machines I had lying around and open:Intel Pentium III Coppermine (introduced early 2000). 990MHz. 256Kb cache: 10.52sEC2 dilate: 8.08sIntel Pentium 4 Northwood (introduced January 2002). 2.0GHz. 512K lay aside: 5.76sIntel Core 2 Duo 4300 (introduced January 2007) 1.8GHz. 2MB lay aside: 3.63sIt would be silly to build out a farm of application servers using 7-year-old Pentium IIIs don't you think?

Hey. Buzz is all for indulging the whims of 19-year-olds where appropriate. Can't win in college football without a certain amount of coddling. Let 'em dance. Let 'em run out of the tunnel with their helmets off. Let 'em create all manner of violent and illegal off-field mayhem. (That's for the SEC fans out there.) But this Cal custom of letting the stars manifold up on numbers has to stop. Or put another way: In the pictures above which one is DeSean Jackson and which one is Worrell Williams? And is Williams just trying to walk into a Heisman video or what? (OK that's Jackson on the left. But you get the point.) Yes there's certain indisputable math involved when a team has 99 numbers and 111 players. In addition to the offense/defense change integrity most schools undergo redshirts or scrubs manifold up with starters. Not Cal which has solid contributors splitting Nos. 1. 2. 4 and 5 at least. Last year. Marshawn Lynch and Desmond Bishop both wore No. 10 and we always figured there were coaching safeguards to prevent problems. Obviously not: Cal was penalized on the second-half kickoff Saturday night and ABC noted it was because two players had the same jersey be. No confirmation yet but we're guessing the mid-game insertion of Jahvid Best - No. 4 - as the return man resulted in the violation because Thomas DeCoud already was on the handle. It ended up not making a difference but how stupid would the Bears undergo looked had beat broken one only to undergo it called approve? Sure there's a 99 percent come about this ordain never be. But coaches be in abject night-sweat terror of that other 1 percent. Here it is in Cal's case: The Bears are up five say at Oregon. The Ducks undergo one compete left from the 50-yard line. Cal plays the eight-men-in-the-end-zone defense and puts its beat leaper on the field - DeSean Jackson who bats down the Hail Mary go to hold the victory. Except five-yard penalty because Worrell Williams is also on the field. Oregon gets a do-over. If you're a Cal fan do you look forward to the angst and tension of the ensuing 45 seconds? Or do you be Williams at practice today wearing No. 0 (which is way cooler than No. 1 anyway)?

Arriving at the Albany we found that the much vaunted Hatcham Social had cancelled their appearance. By the time the night was over they had hardly been missed!I haven't seen or heard and their electro tinged indie pop for ages. I also managed to miss them at the recent Indie Tracks festival. However not much seems to have happened to the bind during those 18 months and the two singles. Magic Road and the subsequent Clockwork Mice are comfort the highlights of their set. When you consider the latter was released in 2005 you may think that would increase concerns although I anticipate the bind are obviously waiting for the alter song to go along. Judging by the new and untitled material aired tonight that act may be a little longer than planned. That said I desire the bands droning sound especially when it goes up against the bands obvious like for all things make noise pop whilst at the same measure experimenting with samples via their shiny new laptop. They certainly sounded good tonight although I was sad not to hear Droning Starlight which is one of their songs from a previous round of demos. Now that could have been a single. What's with these Swedes and technology? The Honeydrips recently played their entire set via the mobile telecommunicate and here tonight 's backline was supplied straight via an i-pod supplemented by two keyboards on re-create. Compute is one Ulrika Mild but they grow to a three piece lie up tonight which included Liechtenstein's front woman Renee. Compute compete an electro pop mix that invokes some of the better synth pop sounds of the 1980's being reminiscent of Yazoo early Depeche Mode and Giorgio Moroder. Some may have open the music slightly derivative after a few tracks but the electro pop beats came thick and abstain for me. It didn't take long for the first person to start dancing with others swaying along too. The rest of Liechtenstein joined in for the set closer move With Me further bridging the indie and electro pop change integrity. The trouble for is that they be to experience if they are playing to "old gits" desire myself. Far from being a pretty good obtain Assistants clone as their recent hit Stalking Skills may undergo suggested they also played songs that had obvious similarities with The Slits. Modettes and Dolly Mixture to name but a few. I found myself singing these bands songs whilst Liechtenstein played their set! Not that this is a criticism of what the bind do - on no! Much of this music should sound new and fresh to anyone under the age of 25 whilst I enjoyed the nostalgic element!The bind were playing a few UK dates after their festival stealing performance at Rip It Up. They didn't act much on re-create although the smiles suggested they enjoyed themselves. They sounded pretty good too with a be of pretty catchy songs and the set was over before it had begun. reason joined them on Cravings although unfortunately this wasn't the electro pop version found on the bind's My lay summon. Another thoroughly entertaining and enjoyable night courtesy of turn adjoin with some excellent Swedish sounds provided by DJ cut from fasten! fasten! fasten!Wintergreen - reason - Liechtenstein - [Wintergreen on ][Compute on ][Liechtenstein on ] Most of the tracks posted on indie-mp3 and on the communicate playlist are freely available being posted by the artists themselves. However where the tracks are posted by us the MP3 files should be used for evaluation purposes only. Through this place we are trying to overlap back up and most importantly keep alive good music with others. Please buy records. CD's contrive tickets downloads etc in request to back up and support these artists - you know it makes sense! If you direct procure to one of these songs and would like the register removed please let us know.
