Has anybody actually gotten a task for either the CPU or the GPU yet?

The server status page shows 500 task ready to send with none in progress, and it hasn't seemed to change at all since they appeared.

I have several of them for ATI GPU, though this machine is still working on some Einstein units and hasn't started them yet.

Yes, problem solved.

Not sure if this is the right thread, but will try anyway. Started working on the MW Separation Modified Fit (OpenCL only) on 2 x GTX660SC @ 2Gb. Each task is currently using .503 core & 1 GPU. The problem is they are using only approx. 69-75% of the GPU. What do I need to have the CPU & GPU set to .5, so that I reserve a half core CPU, and still run multiple (2) tasks per GPU attempting to get 99% usage?

I am also working Milkyway (OpenCL only) using the default app_info.xml, increasing the GPU to 3 tasks in an attempting to reach 99% usage.

app_config>
<app>
<name>milkyway</name>
<gpu_versions>
<gpu_usage>0.33</gpu_usage>
<cpu_usage>0.5</cpu_usage>
</gpu_versions>
</app>
</app_config>

Hmmm...

Are you using all the CPU cores to run tasks? I found I have to leave one free to drive MW, Collatz, and SAH to max GPU utilization. That gives me 98-99% for MW, and Collatz, and generally better than 95% for SAH (IOW's BOINC restricted to 7 of 8 on the FX-8350).

EAH is a different story. Apparently, it needs far more CPU support for the GPU so I have it spec'ed so when more than 4 want to run it will grab another CPU to help out and even then I can only get to about 85% by running 4 each on my dual 7970's.

<edit> Oh yeah, the MW, Collatz, and SAH data was for running 4 each on the duals, as well.

I'm running BOINC @ 90% (7 cores). Normally I run only S@H AP (both CPU & GPU) on this machine. When the GPU tasks run out, then MW kicks in to fill the GPU gap. Since my earlier post, I've figured out what was needed for the MW app_config.xml file. Right now I running 5 S$H AP CPU tasks, with 2 each MW Separation Modified Fit per GPU, and the GPUs are running at 99%. Whenever I will get some MW OpenCL tasks, they too will run with .5 core reserved for each task and is set up to run 4 tasks per GPU.
