I've run into an odd problem. I first installed Boinc about a week ago and attached to Seti@home and Rosetta@home. I'm running a dual processor machine and Boinc originally used both processors to full extent (one for Seti and one for Rosetta).

Recently, Boinc uses only one processor and I can't figure out why. If I run CPU disgnostics, the messages window reports 1 processor. However, Boinc's XML data files seem to indicate 2 processors:

client_state.xml: <p_ncpus>2</p_ncpus>
(every file with a "p_ncpus" tag indicates 2 processors)

I also run Gkrellm and I can see both processors are active. So it's not a hardware problem.

My preferences set "Max CPUs" to 0. So it shouldn't be a preferences problem either.

Is there anything I can do to encourage Boinc or bootstrap it into using both processors? It may be irrational, but unless Boinc uses both processors, I'm tempted to remove it completely.

Boing manager: 5.4.9
Fedora Core 4

It seems the Boinc general preferences page changes. There's no lnger a Max CPUs option, and it's replacement was set to "1." The new option doesn't seem to support setting the value to 0 (to use all processors). Anyway, I changed the setting to "2" and updated through Boinc. Everything seems to be back to the way it was previously.
