SETI, Einstein, Message runs at lowest possible priority. If CPUIdle is active then CPU is shared 50% for BOINC and 50% for CPUIdle. When LHC starts, it uses 100% CPU and does not leave anything to CPUIdle. Because it is hot where I am (room temp. 34C now), the computer runs very hot and if loaded 100% it overheats and crashes. If 50% CPUIdle then everything is OK. This problem prevents me from running LHC@Home for now (despite of the fact, that my PC has a lot of unfinished workunits). Looking forward to this be fixed in the next version:) |

Check out this link. Down the page a little bit is a utility called ThreadMaster. Although I've never tried it, it seems like it should do what you are wanting it to do. > SETI, Einstein, Message runs at lowest possible priority.

Also, make sure your heatsink is on properly. Had an IBM craptiva that crashed all the time. After getting a new machine, noticed that the heat sink on the old craptiva wasn't on right. I'm not the LHC Alex. Just a number cruncher like everyone else here. |
