The problems with the folding@home smp client and quad core cpus seem to be
kernel 2.6.25 specific. Fedora9 user have very similar problems that sum up
to three at the moment. The f@h discussion is going on here:
http://foldingforum.org/viewtopic.php?f=12&t=2937
1. running one linux smp client on a quad core cpu results in only 30% cpu
usage. (on an "old" suse 10.3 about 65% cpu is used)
2. eventually the smp client dissappears from "top" but is still shown in "ps
x" as running. The log shows that there is no progress on the wu, but no
error message either.
3. ssh login sometimes takes minutes to accept the password.
Tested with opensuse 11.0rc1, amd Phenom9600BE and intel X3350
Please tell me what I can do to find the root of the problems.
Michael
