Message 52891 - Posted: 9 Feb 2012, 0:59:22 UTC - in response to Message 52889.  

In my "ultra-low-end" GT 520 I'm getting this message in results:
Estimated Nvidia GPU GFLOP/s: 104 SP GFLOP/s, 13 DP FLOP/s
Warning: Bizarrely low flops (13). Defaulting to 50

Bizarre ;-)

Maybe this 13 GFLOP/s info is correct and the default of 50 is too high, affecting the estimated time of polling period...
The AMD drivers have an issue that seems to show up every few driver releases where they are detected as 0 or very low Mhz so that is supposed to catch that breaking; I thought the 50 threshold was a bit lower than any DP GPUs which actually exist.

Message 52892 - Posted: 9 Feb 2012, 1:01:23 UTC
Last modified: 9 Feb 2012, 1:06:08 UTC

I have upgraded my BOINC version to 6.12.34, inserted the app_info.xml file in the milkyway@home project directory as instructed (downloaded from the link kindly supplied by arkayn), and am still not getting any WU's. If there is anything else that I can check or may have done wrong, suggestions would be greatly appreciated.

Also, I'm not entirely sure what the app_info.xml file I just inserted in the milkyway@home project directory actually does. I understand about downloading the application and the fact that older BOINC versions don't necessarily recognise graphics hardware as appropriately OpenCL capable, but what I'm not clear on is what the app_info.xml file does with regard to correcting this. Will the one app_info.xml file be universal to all machines utilising AMD graphics cards that are OpenCL capable? Does my CPU type, clock, core number, or my PC's operating system not require any tweak to the app_info to make this application run properly?

Thanks to everyone for the support on this forum and I would appreciate any reply I can get, because I'm confused and just trying to figure out if I've done something wrong trying to get work for this project. I just want to help! Milkyway is a great project, happy crunching everyone!

Message 52893 - Posted: 9 Feb 2012, 1:42:30 UTC - in response to Message 52888.  

Everything errors out immediately on a Mac mini Core 2 Duo running OS X Leopard (10.5.x) since the update to 1.00. Everything was fine with 0.82.
I can't find other cases of that, but I reverted the OS X ones anyway since I guess nothing relevant for it was changed anyway.

Your CPU counts a 2nd device on AMD's OpenCL.

Using Catalyst 11.3 it looks like. Try a newer driver. I am sort of aware of a few various crashes with different Catalyst versions on different GPUs. I think 11.3-4 and 11.10-11.12 are the most problematic versions; 12.1 seems to be working most consistently on everything. Around 11.3 the binary format stuff was introduced (which it says it supports) but it's probably crasher around then.

FWIW, OSX 10.6.8 Boinc 6.12.35 MWAH 1.00...

Received 7 1.00 WUs, processing normally (4 completed as of now). MWAH will not send any work either automatically or via manual update. Server status indicates everything functioning normally...

Any clues as to why no work issuance?

Message 52897 - Posted: 9 Feb 2012, 2:15:54 UTC

Is there a command that can be added to the app-info file that will throttle back the GPU usage. It's now running @ 99% and I really don't want to run it that hard.
Thanks.

You can raise the target frequency with the --gpu-target-frequency argument, or you can do it in the project preferences now which would be less annoying.

And, now all WUs complete, task queue empty & computer idle, log says, "Project has no tasks available", server status as of 2:18:32 UTC, "Tasks ready to send 1,980" and "MilkyWay@Home unsent 1,759 MilkyWay@Home N-Body Simulation unsent 221"

I have no idea if this is symptomatic of the problem ... however its been stated above that its probably connected with recognising OpenCL capability on some cards. The lines below seem strange as I am sure before it also claimed to see GPU1 as OpenCL capable, whereas now it only claims one is. That ties in with a download I did get at one point - just two WUs on GPU0

That stuff isn't in my department. I've been seeing that sort of too, but that's the BOINC client's problem.

Oh derp. Since last time I did this I updated to Lion and I forgot the 10.5 SDK was removed from the new stuff so it turns out I was building against the 10.6 SDK. I rebuilt it as 1.01 for the OS X ones.

Message 52906 - Posted: 9 Feb 2012, 3:47:50 UTC

Hi

I attached Milkyway@home and Milky won't any files. I did check this from boinc programdata milkyway folder. So no work,no exes no nothing.
My win7 64 bit+amd 6950 and 5830 were crunching everything ok before this update to 1.00.

I have Boinc 6.12.34 x64 version and Boinc 7.xx versions won't even start running(no boincmanager window would start even fresh windows 7 instal or deleting files manually after unistal) so it won't solution for this milkyway issue for me atleast.

Any ideas?

Thanks for the quick action. I will have to wait until work is available to see if it works. My Mac mini Core Duo running Tiger (10.4.x) is still working on several units with the 0.82 version. I hope it continues to work when it gets the 1.01.

Plus SETI Classic = 21,082 WUs

Anyone actually manage to get the Linux x86_64 opencl app to work? I have an HD 4870 and it looks like I've been upgraded out of the ability to crunch. The 4870 doesn't like the new AMD drivers and it doesn't appear that the new app likes the old one.

This couldn't have waited til after the double credit day?

What problem are you having? The 4870 drivers were broken with the OpenCL stuff from 11.8 to 11.12 or so. 12.1 works.

I'm currently at 11.8 because anything (stable) after that broke other OpenCL apps. I see that 12.1 is in Gentoo Portage, so I'll try that. Thanks for the info.

Right now I'm suspecting that people aren't getting work because it seems that clients < 7 don't report having OpenCL and I updated the scheduler to check for the new stuff.


What combination and version of Windows os, catalyst driver and BOINC manager have you tested the new application on?
It's not the application, it's the project scheduler


Hmm... ok. What combination and version of Windows os, catalyst driver and BOINC manager have you tested the separation applications 1.00 against? I want to know caus I'm not getting any WUs. I gues that you have tested against some combination of OS & drivers or are you just make an update and hope for the best? ;)
