When I update to 6.4.6, only one of my two CPUs are running WUs. I have one GPU running also. I went back to 6.6.9 and both of my CPUs are running WUs. Is there a resource issue?

6.4.6 is an update of 6.4.5 with fixes to the screen saver code. It will probably still need the flag in cc_config.xml when you want to use all CPUs plus the GPU.
Please do not private message me for tech support. Use the forums for that. Tech PMs will be ignored.

More than probably you have conflict issues between website profile settings and the local prefs. In 6.x there's an option to set the %, but in the global_prefs_override.xml there still could be the old X cores setting. Clear the local prefs and verify the website profile shows 2 cores and 100%. The logic I think is the least of the 2 and rounded down, thus 90% also translates to 1 core on a duo.

hmmm, quick check on BFS cc_config.xml page revised Feb.9,2009

Act as if there were N CPUs: run N tasks at once. This is for debugging, i.e. to simulate 2 CPUs on a machine that has only 1. Don't use it to limit the number of CPUs used by BOINC; use general preferences instead.

For use with CUDA: When you want to do CUDA only, not use the CPUs at all, set <ncpus>0</ncpus>
If you want to use all CPUs, either omit using this option, or set <ncpus>-1</ncpus>

Now that's one seen in past and never used myself or actually seen it used.
