I'm still having a problem on two of my three machines (ID: 518375 and ID: 518536). I have to keep hitting "update" every hour to get any new WU's and even then I only receive 5 or 6 which I burn right through. My global settings are all for 5 days + 1.

All of the machines are Linux/Nvidia/Boinc 7.1.18 and virtually identical.

Any suggestions would be appreciated.

Steve


Are you using a cc_config file? If so they changed the name of the workunits and until you change your file it won't work!



Mikey,

I'm using the stock cc_config but there's no mention of apps. Don't you mean the app_config?

Here's what I'm using for the machines.

<app_config>
<app>
<name>milkyway</name>
<gpu_versions>
<gpu_usage>.5</gpu_usage>
<cpu_usage>.05</cpu_usage>
</gpu_versions>
</app>
<app>
<name>milkyway_separation__modified_fit</name>
<gpu_versions>
<gpu_usage>.2</gpu_usage>
<cpu_usage>.2</cpu_usage>
</gpu_versions>
</app>
</app_config>

Thanks for any help you can provide.

Regards,
Steve

My "dedicated" Milkyway@Home computers continue to crunch AMD GPU work units, but I have since moved their cpu's over to Cosmology@Home and it's proving to be a smart decision. :)



The problem with Cosmology is that it doesn't have any GPU WU's. If that's of interest to you, you might try Einstein@home.

I too, am having this problem with one of my 3 machines. I'm running BOINC 7.1.10 on all of the machines and they are all virtually the same (NVIDIA GPUs, AMD CPU's, at least 8GB of RAM, Linux Mint 15, etc.)

On the problem machine (ID: 518536), I have to keep hitting "update" to get a new bunch of WU's and then it only sends me 5-7 WU's so within an hour, I'm hitting "update again.

I tried doing a reset but it didn't make any difference.

If this is off topic for this thread please point me in the correct direction.
I would like to not use windows for my AM3 and HD6990 cards,
I can not get the GPU drivers installed in Ubuntu properly.
is there a step by step guide, or a simple way to start using a linux os?
Thank you for your assistance.
Greg


I'm running Linux Mint 14 and 15 which is based on Ubuntu so here goes.

As Mikey said, you do need the "Restricted Drivers". In the past, there was a separate menu option for this but recently Mint (and maybe Ubuntu) have moved it so that it is a tab under Synaptic.

The other thing is that for the GPU's to work try the following.

BEFORE YOU START BOINC MANAGER every time ......

Open terminal as Admin or as sudo

sudo service boinc-client restart

You should get a bunch of "ok's",

goa ahead and close terminal

and THEN start BOINC Manager

Hopefully, that will do it for you. If not, depending on what happens (or doesn't happen) we'll try again.

Also, if you don't see any GPU WU's, look under the event log up near the start to see if there are any references to the GPU.

Steve

Could anyone tell me what the video ram requirements are for the different types of MW WU's? With E@H, for example, 300MB is the number when you're trying to decide how many GPU WU's your card can handle simultaneously.

Thanks for any information that you can provide.

Thank you for providing the backstory. I certainly share your sentiments on a number of levels. As an interested supporter, but not a programmer, who has dedicated some decent boxes to BOINC, I want my spending to be used in the most efficent manner that supports all of the projects that I participate in. It may not amount to much from a NASA grant perspective, but it's something to me and I'm happy to provide it as long as the projects hold up their end.

I guess that's why I'm so interested in being able to process the multiple simultaneous WU's whether it's through app_config or app_info files. If an project app won't support that and then wants to tie up my GPU with it's 2GB of VRAM but is only using 300MB of it and in the process denying the GPU's concurrent use to other projects, that hurts everybody in terms of wasted resources.

Thanks again for the feedback.

Steve

Richard,

Thanks for the correction, it's been incorporated.

I have to ask, are you really sure about no GPU WUs for the N-Body Simulation 1.09 because I not only seen a notation of (opencl_nvidia) after some of the WU's but the one that's waiting also says (0.05 CPU + 1 NVIDIA GPU). It's waiting right now on some E@H GPU WUs to run but I could have sworn that when it was running none of the available E@H were.

Also, I was wondering why the N-Body WU's 1.09 that are not marked as cuda all seem to have very short expected durations (most under an hour) while the cuda-marked ones are all well over 20 and even 30 hrs! I almost felt like I was having a Cosmology@Home flashback!

Thanks for any further info you can provide. Enquiring minds want to know! :)

Steve

I've gotten my two BOINC machines changed over to Linux Mint 15 and BOINC 7.1 and wanted to provide an update as well as well ask one or two final questions. I have had some success.

To recap, all graphics cards are Nvidia Fermi's and each machine has at least 8GB of RAM.

Machine 1 has the following 2 Fermi cards:
Sun 19 May 2013 05:24:58 AM EDT | | CUDA: NVIDIA GPU 0: GeForce GTX 460 (driver version unknown, CUDA version 5.0, compute capability 2.1, 767MB, 691MB available, 1009 GFLOPS peak)

Sun 19 May 2013 05:24:58 AM EDT | | CUDA: NVIDIA GPU 1: GeForce GT 430 (driver version unknown, CUDA version 5.0, compute capability 2.1, 1024MB, 1009MB available, 269 GFLOPS peak)

Sun 19 May 2013 05:24:58 AM EDT | | OpenCL: NVIDIA GPU 0: GeForce GTX 460 (driver version 304.88, device version OpenCL 1.1 CUDA, 767MB, 691MB available, 1009 GFLOPS peak)

Sun 19 May 2013 05:24:58 AM EDT | | OpenCL: NVIDIA GPU 1: GeForce GT 430 (driver version 304.88, device version OpenCL 1.1 CUDA, 1024MB, 1009MB available, 269 GFLOPS peak)

The system is processing two concurrent MW 1.02 cuda wu's simultaneously, so success there. However, no matter what I do with the cc_config.xml or the app_config.xml, I can't process more than one N-body Simulation 1.09 cuda wu at a time. In fact, it looks like it only sends them to GPU 1 which has more video ram as if that might be required. It makes me wonder if the cuda N-Body Simulation GPU WUs are so computationally intensive that you can't run muliple simultaneous WUs of the 1.09?

I made sure that all file ownerships were the same (BOINC) so that's not an issue.

My first app_config.xml was:
<app_config>
<app>
<name>milkyway</name>
<gpu_versions>
<gpu_usage>.5</gpu_usage>
<cpu_usage>.05</cpu_usage>
</gpu_versions>
</app>
</app_config>

When that didn't make a difference with the 1.09's, I remembered from the app_info.xml's that the N-Body's had their own section and file name so I changed the app_config.xml to:
<app_config>
<app>
<name>milkyway</name>
<gpu_versions>
<gpu_usage>.5</gpu_usage>
<cpu_usage>.05</cpu_usage>
</gpu_versions>
</app>
<name>milkyway_nbody</name>
<gpu_versions>
<gpu_usage>.5</gpu_usage>
<cpu_usage>.05</cpu_usage>
</gpu_versions>
</app>
</app_config>

No errors noted by BOINC but also no change to the processing of 1.09's unless it takes some time to cycle through the system. If so, it makes it hard to troubleshoot problems if the changes don't reflect fairly quickly.

I'm going to run down the cache and then let it re-load one more time. If it's still not running multiple concurrent 1.09 wu's I may stop doing the N-Body's since it really ties up the GPU and not only denies it to the MW 1.02 cuda wu's but also to E@H.

Situation is the same with machine #2 which is a Fermi 550TI with 2GB of VRAM.

Thanks again to everyone for their suggestions.

Steve

I do use gedit/Pluma (same thing). Good point, on the file permissions issue. These installations are years old and through the updates, something may have gotten changed. Doing a fresh re-install will let me start off clean.

Actually, it's not a big deal since these are Boinc-only machines so it's not a case of having to do any backups or re-copying of databases etc.. Once the system is re-installed that will also eliminate any compatibility questions among versions that may have crept in over the years. Also, as one person noted, with Linux you have to watch the file permissions so this will let me start with a clean slate.

It looks like the final Cosmology wu's will be done tomorrow so we'll see what happens then.

I wanted to thank everyone for their suggestions.

What I've decided to do is to work off the existing WUs on all of the machines and upgrade the OS to the latest version (Linux Mint 14 from 12) since I see the latest BOINC (7.0.65) in that repository. After upgrading the BOINC installation and running for a few days, I'll see how things look.

Oh,yes. The cpu wu's are all happy on their cores and the GPU is crunching just one of the available cuda wu's at a time.

Since I'm on Linux, the choices are gedit or Pluma which are basic text editors. Since I've used them in the past when I had working app_info.xml's, I don't think they're the problem.

Just on the off chance, I just tried things again using app_config.xml and then an app_info.xml boyh created with Notepad under Win2000. No change.

Thanks anyway.

Thanks for the suggestion but still no luck. I'm wondering how I'm able to run multiple simultaneous GPU WUs on that one machine given that we're talking about the same brand of Fermi 460 card in two of the machines. One works, the other only processes one GPU WU at a time; a real waste of HW power.

I'm curious as to how many others are having this problem, how many have solved it, or how many have given up and whether OS makes a difference.

Oh well, time to go light more incense!

Arkayn,

Thanks for the suggestion. Everything looked like it went fine with adding the repository and I can see it listed in Synaptic after the update/upgrade, except that when I have Synaptic search its listings for "BOINC", it still shows the old v.6 ones.

I think I'm going to try a new installation on a different version of Linux and see what happens since all of my machines are virtually identical down to the brands and models of the components.

The good news is that, at least, I am processing MW GPU WUs, just not multiple ones simultaneously.

Thanks again.

Steve

While the machine with the Fermi 460 and the 420 cards is now running great with multiple, simultaneous GPU WUs being processed using the corrected app_info.xml, I'm still having a problem with the other two machines and the GPUs.

To recap - all machines are running Linux Mint with NVIDIA GPUs. All machines are seeing and apparently running all of the types of WUs sent without problem. The snag on the remaining two machines is that they can't process multiple simultaneous GPU WUs. I've tried both the fixed app_info.xml that's working on Machine one as well as an app_config.xml mentioned on the message board (both with and without the <max_concurrent>4</max_concurrent> line) but no luck.

One machine has a single Fermi 460 while the other has a Fermi 550I (dual GPU but only one seems to be seen no matter what I do.

The machine with the Fermi 550I is still on BOINC v.6 but I'm trying to find a reliable repository to upgrade from. The machine with the single Fermi 460 (running Linux Mint Debian Edition) does offer Boinc V.7 and that's what's installed but it doesn't make any difference.

Is there another config file somewhere that still has to be checked?

FWIW, Einstein is working with no problems at all on the GPU front although they went to a different approach some months back where now you just check off on your E@Home prerences page if you want to run simultaneous GPU WUs and it's taken care of there. No app_anything.xml files.

Thanks for any help you can provide.

Steve
