World Community Grid: Launch of Graphics Processing Unit (GPU) capability for the Hel

[John P. Myers]

No, it's the same credit per wu, regardless of CPU or GPU, meaning going by your example the GPU will get 2x credit/day compared to the CPU.

In reality the speedup is much higher, for my Ati-HD5850 running on i7-920 the speed-up is around 22x, and this means GPU gets roughly 22x more credit/day compared to a CPU-core.

Sounds great for getting credits, but for those chasing badges (based on time, not credits) there's no improvement right? More work and more electricity to gain badges at the same rate?

Badges are based on CPU time, which is small for GPU tasks. So you will get some small help on badges, but nothing compared to CPU tasks.

This will be an interesting chart to watch:

For those of you looking for an AMD app_info.xml file I was able to modify the CUDA file that Rattledagger found on the WCG forums to work with my 7970.

Here it is:

You can run 4 tasks at a time? What's the run time and GPU load?

[grathomp]

I'm still trying to figure out how many instances of the application is optimal for my system, but I thought I would post a working app_info for people to adjust their <avg_ncpus> <max_ncpus> and GPU <count> according to their specifications.

When I run 8 tasks my GPU load maxes out around 95% but will dip if enough tasks are nearly complete and switch to CPU only. Tasks are completing after about 5 minutes.

8 tasks every 5 minutes is very good.
Didn't work for me. Got an error from the startup log. Unfortunately it didn't copy and paste.

[grathomp]

I attached my app_info.xml as app_info.txt

This time it's for 4 workunits per AMD GPU each using one CPU core. Hope this helps.

Still not working for me. Get this from message log.

stop all tasks that you have on Boinc or just canceled them without any tasks Boinc will start downloadind.

No tasks running. I finished them all before using the app_info file.
