Message 29790 - Posted: 27 Aug 2009, 15:55:15 UTC - in response to Message 29789.  

Thank You for the reply. I re-read the first post/message and found the
preference for the project. I have the GPU selected as NO.

Use GPUs for Computation? no
Use CPU for Computation? yes

The problem is that it does not work. I ran update for the project and it still trys to get work for GPU and does not try to get CPU work. So that means I will run out of work very shortly.

Thanks again. Jim

Is the client out of CPU work?

The one machine is out of all work, had to enable a different project to keep it busy. It won't switch to CPU work.

I've made a post to the boinc_projects mailing list about the issue.

Anthony, I found something wrong. When my CPU (i7) is working full with other BOINC projects, calculation time for Milkyway/CUDA is 9.5 minutes. When my CPU is idle, calculation time is 5.5 minutes. Close to two times difference !

Edit: confirmed on my second computer.

The estimated calculation time? If so I'm not sure how that is calculated, the progress bar is the best estimate for how things are progressing.

On my Q9450/GTX260, my estimation time is 12:55 when it's running full CPU. When I stop the CPU project, calculated time is 5:45 and estimation time start to decrease.
To be sure, i reduce the number of CPU for BOINC from 4 to 3 => calculation time continue to be 5:45 mn.
Another thing, When CPU is idle, calculation time on GTX295 is close to GTX260.

Message 29801 - Posted: 27 Aug 2009, 18:27:40 UTC

Thanks Anthony, I later got some time to read bout the 'nix.
my win is one of the test ones (beta) from back in '02 and never have i got it to run anything 32 bit , even the 32 bit ms browser,it wont run firefox, mspaint nothin'... lol i got what i paid for. 32 bit apps sent to 64 bit BOINC all fail aswell. in the past i'd hunted down all the missing 32bit libraries to no avail. only put it on that box 'cuz seti gpu sends no tasks to 64bit 'nix

After several tests, here's what I see with calculation time:

1/ Q9450 (4 cores) and one GTX260:

- When CPU is idle => 5:45 mn.
- When 4 cores are running => 12:55 mn
- When 3 cores are running => 5:45 mn

2/ I7 920 (4 cores, 8 threads) and two GTX295 (4 GPUs):

- When CPU is idle => 5:38 mn (same time on each GPU)
- When 8 threads are running => 9:30 mn
- When 7 threads are running => 9:30 mn
- When 6 threads are running => 5:38 mn

I hope it could help.

Thierry.

I believe MW have the almost the same source code as Collatz, my 250 card on collatz is giving more credit than a 260 gpu on gpugrid.

My GTX295 is doing the WUs in about 7 minutes under XP x64 sp2 w/Boinc 6.10.1 and 190.62(WHQL).
12/21/2012? Bah Humbug!

Could you make a test with idle CPU and another with CPU under full load ?

Thanks,
Thierry.

Without losing a lot of work(MW and S@H) I don't see how I could as both use the cpu.

The GTX 285 that I have takes about 5:24 per WU with no load on the CPU and leaving the computer idle, this is with the WU that begin with gs_s222_3s.

Yes, but I'm talking outside Milkyway load on CPU, like another BOINC project.

OMG how messed up, if you dont like my 9500GT and 8800GTS for Cuda, than even nothing at all.
Lol how foolish to ignore the most aviable Graphic Cards all over. Are you thinking, nearly everybody have a GTX285? xD

It is for technical reasons....

CC 1.3....

P.S.

I confirm all previous results....

MW takes 5m 50s when crunching on GPU alone.....

When with other cpu project it takes.... even 12m 30s.....

So here is great area for coders to improve app...
