Just as an info, I run now 4 WUs at a time on a GTX 480 :

- GPU Load: +/- 84%
- Memory used: +/- 1350 Mb
- T°: 68°C
- Fan speed : 78%
- Run time: +/- 95 minutes

Cool :-)

4 WUs on a GTX 480

and what is gpu load for 3, 2 and 1 WU at a time?

Between 62% (1) and 84% (4).

you have to check 2 and 3

you have to check 2 and 3 too, because i have info what 2 and 3 WU make the same load for GPU as 4. if so, there is no reason to make more than 2 WU.

How many CPU cores are used in support? In other words, how many concurrent CPU-only tasks (of anything) are you running? Is the elapsed time for crunching a CPU task (the wall clock time - not reported CPU time) being significantly affected? Have you actually measured wall clock time to see how well it agrees with what is reported for Run time?

What settings do you use for and

Quote:
- Run time: +/- 95 minutes


So, every ~95 minutes, you complete 4 CUDA tasks? Pretty impressive!

My keen interest stems from the fact that I don't (yet) own any CUDA capable cards but I do want to crunch the Parkes work (efficiently - ie not on a CPU) for as long as it lasts. In terms of Australian distances, that facility is just down the road from where I live :-).

I have 12 ATI 4850s crunching MW and I'm considering an investment in some suitable CUDA capable units in the interim while I wait to see if there is a successful port to OpenCL. The commentary about an OpenCL version has moved from "unlikely any time soon - if ever" (admittedly made quite a while ago) to "perhaps later in 2011" made about 9hrs ago. The reality will probably be "some time in 2012" :-). With your type of numbers being bandied about, it's very tempting to put more pressure on an already overblown budget :-).

Cheers,
Gary.

I have an I7 CPU. It runs

I have an I7 CPU. It runs (for the moment):

- 4 * Einstein (0,20 CPUs + 0,25 NVIDIA GPUs) +
- 4 * Spinhenge WUs at 80% +
- 4 * Spinhenge at 100%

But the 0,20 CPUs, following the Tasks Manager, is in fact 0,40 CPUs.

Yes, 4 WUs every 95 minutes

The avg_ncpus is 0.2. But as I'm not a specialist, I use app_info file copied somewhere. I only changed the CUDA count.
Here's my app_info file:

what about gpu load for 2 and

what about gpu load for 2 and 3 WUs at a time?
upd: ok. thank's. sad, what my gtx 560 can't hande more than 2 WU because 1024 is not enough even for 3

The memory used is: - 433

The memory used is:

- 433 Mb for 1 WU
- 710 Mb for 2
- 1000 Mb for 3 (from 965 to 1035)
- 1300 Mb for 4
