Is this the way it is supposed to run? I thought I would be using 4 cpu threads and 1 gpu thread.

Just got the install to work today on Linux Ubuntu64,9800GT graphics card, and BOINC client 6.3.10.

Yes. The project can vary how much CPU is allocated. Currently it is set to use 1 CPU, although it only actually uses something like 4% or less of 1 CPU (or core). We are still studying which way has the best performance.

Clients 6.3.14 and up will show you next to Running how much CPU/CUDA is allocated.

If you want to run 4 CPU + 1 CPU/CUDA you can by using the ncpus+1 trick, amking BOINC think you have 5 CPU's. 1 CPU will ahve to share a little. See other threads which cover this.

Thanks Keith I will surf some more....now the grid task has paused and am back to 4 CPU's...I intended it to run ncpu4+1gpu and let the gpu stand alone so I need to configure it I guess

I should mention, if its not in the other threads, running ncpus+1 has a drawback. If your resource shares are too low for the GPU project, or the GPU project runs out of work, you will end up with 5 CPU tasks running, the drawback being 2 of them will be sharing a CPU core and not running at full speed. This may be OK for a short term, but if your are going to be out of GPU work for a long period you may want to go back to no ncpus setting.
