Greetings everyone...
Here's my newbie SMP set up:
Two 866MHz P-III's... One with the cD0 stepping and the other is a cC0.
Intel's documents have informed me that mixing these steppings is ok.
The mobo is a Asus CUV4X-D dualie. The SMP FreeBSD kernel runs like a
charm.
My only concern is when running dnetc (the distributed.net client) it can
freeze the machine when chewing through its blocks (which generally lasts
for few seconds when it happens) after which the machine will wake up as if
nothing happened. If I run top before this occurs and wait for the machine
to lock, top seems to wake up and the two dnetc instances look as though
they're using 190+% CPU *each*. dnetc will continue to run properly until
it is killed. Is this (relatively) normal with CPU-intensive programs like
dnetc? I searched distributed.net's bug archive for SMP problems and only
found a 'Bus Error' bug -- seems unrelated as it results in dnetc dying. I
haven't been running dnetc since I noticed this happening and nothing else
seems to cause this problem that I have noticed so far.
Is this a symptom of something else? Could this be related to the mixed CPU
steppings? Am I just being paranoid?
Thanks,
-Andrew
