Message 30352 - Posted: 7 Sep 2009, 21:56:31 UTC - in response to Message 30346.  

So I cant use opti app to Run CPU? I was hoping to run cpu and gpu, but cpu is too slow without opti app.If I rename file will it still run opti app?


Let me think on it and test it...

Ok I'll check back in awhile. Thanks for your help Logan.
;-p


Sorry... I tryed some things but don't works...

Now I have other things 'to do'... Sorry if I can't help you now (by the moment).


Best regards.
Logan.

Of course...

In the project web page, select 'your account'. Next you can select 'view tasks'. when you find a 'completed task' make a click in the number called 'Task ID'. Then you can see the log of your task.

I.e. your task log

Isn't your computer fault. CUDA MW app now takes a lot of your user interface time... Are them who must to fix it...

It's doing the exact opposite. It's requesting GPU WU's and not requesting CPU WU's.

I'll wait for a little more help before suspending this project and waiting for updates to it. Laudable & fascinating goals but I object to subjecting unwilling volunteers to bugs.

Well...

Check only the GPU work in 'your preferences'. And reset the project. Be sure you have a GTX2XX card and 190.38 driver or greater.

@ Logan
I renamed the file and have a full cache of GPU WUs now, maybe if we find a way to make it work I just have to put the old name back.Anyway thanks again for your time and trouble.

What is the button on boincmanager > advance > preferences > use GPU while computer is in use?

If not clicked in computer waits until mv cuda start up to 10 min, and if clicked in, it start ok, based on preferens: 'In use' means mouse/keyboard activity in last 2 minutes or what ever...bla bla blaa..

That button don't make any different in other cuda projects, but here it do?
Why?

My GTX295 is doing the WUs in about 7 minutes under XP x64 sp2 w/Boinc 6.10.1 and 190.62(WHQL).


Thats strange.. I assembled my new computer today.. and run CUDA WU for the first time.. With low CPU usage compared with high CPU usage i did not notice much difference.. maybe 30-60sec on one GPU WU..

But my WU (the first 3-4 ones) finnied in 4min area.. And the rest 25 took around 5 minutes...

Thats strange? You have a GTX295? ...

My specs:
Core i7 920 @ Stock speed, GTX275, 6GB RAM .. Nothing special...
My GPU temp is around 75c when running in a room 25-26c ... And CPU temp with 100% CPU load and 8 tasks running is 55-59c in the same room.

EDIT: forgot to mention Boinc and OS
Boinc 6.6.36 OS: Windows7 64bit

@scibuff:

The device Device Emulation (CPU) from the command line cannot be used


Your CPU is using the emulation library for CUDA, hence boinc thinks it is a GPU, but the library has 'older' compute capability, so it is rejected.

I am not familiar with the command line, but some searching for 'emulation' might help. I recommend switching that option off, wherever it is set.

If I understand you correctly you want to run the optimized CPU app and the CUDA app in parallel.

Here is an app_info.xml which should just do that (adapted from lunatics). You have to change the name of the CPU app to the one which you are actually using (in my case this is the 64bit SSE3 version)! Stop Boinc, create an empty text file in your milkyway project directory (this is were also the optimized app is located), copy everything from below in it, rename the file to "app_info.xml", start Boinc (previously downloaded CUDA workunits will be discarded). Absolutely no guarantee that it will work - it works for me though...

There is an issue associated with executing CUDA applications through BOINC when using Linux/GNU. The application will execute correctly when run through a terminal, however, when BOINC fork+execs the application it will segfault within NVIDIA's driver [1].

Since i'm experiencing the same trouble over at collatz, having boinc trash my cuda app, we now figured out that this issue only applies to the 6.6.x boinc clients.

The new 6.10.x clients work just fine and don't crash the cuda app any more.

Is there anything I can do to crunch CUDA while using my PC without having my screen blink everytime a WU is completed and the next one started?

I'm running 2x GTX260 under W7-64 Ultimate with the 6.6.38 client.

I'm running MW on Windows 7 32bit, BOINC 6.10.4, nVidia GTX275. There doesn't seem to be an optimized app for Cuda and therefore doesn't have an app_info so that I can set the "<count>.50</count>".

Is there something I need to do to get the most out of this box? Any help would be appreciated.

Thanks,
