1) Message boards : Number crunching : Cuda and bonic version 6.4.5 problem (Message 867612)
Posted 21 Feb 2009 by Profile Far Star
I'm running BOINC version 6.4.5 on an Intel Q6600 Quad processor CPU with an NVIDIA GeForce 8800 GTX GPU. Right now I have one Astropulse 5.00 WU, one SETI@home Enhanced 6.08(cuda) WU amd two MilkyWay@home 0.19 WUs crunching. Using Process Explorer, I see the three non-cuda WUs all running at about 25% (full utilization of 3 out of 4 CPUs). The fourth CPU, working on the cuda WU, is running at about 0.4%. Meanwhile I am seeing explorer.exe jumping around between 0.3% and 20 %. When explorer.exe gets up above about 2%, the cuda WU goes to 0%. As noted by others, other apps are extremely slow when running BOINC.

Suspending the MilkyWa@home does not improve the situation. Exiting AVG and Spyware Terminator doesn't help either.

The following seems to help. Suspend the cuda WU, which allows a MW@home WU to start up. Now resume the cuda WU and suspend one of the MW@home WUs. The cuda WU now runs at 1% to 5% and explorer.exe is between 0% and 1%.

Just now the cuda WU has finished and a new cuda WU has started. I am now back in the situation I was in at the start of this post. the cuda WU is running 0% to 0.3% and explorer.exe is 0.3% to 20%. Other apps have slowed to a crawl.
