Hello all.  I have a Tyan Tomcat II (purchased August 1996) with two 166
Pentiums, 64MB RAM, Addonics Sound Card, Matrox Millenium 4MB, and assorted
IDE/ATAPI devices, running the 2.0.29 kernel (via Slackware 3.2.0) recompiled
with the SMP=1 switch enabled.  I have a few questions:

How can I tell that both processors are being used? (I just recently installed
the second one.)

Are there any particular options for compilation which would help optimize
programs to use the second processor?

I have noticed mention of various kernel patches which are being used commonly
by members of this list.  What are they, and if you would recommend installing
them prior to recompiling my kernel (which I will do again if it would allow me
to improve or monitor usage of my CPUs), where can I get them?

Finally, is the 2.0.29, to the best of anyone's knowledge, stable with SMP, or
should I upgrade or downgrade to a different kernel?

Thanks for any expertise you could share; it would be greatly appreciated, as I
will be using the system for biomolecular modeling, for which I specifically
bought the second processer -- now I'd like to use it!

   "Tereza kept stroking Karenin's head, which was quietly resting in her lap,
while something like the following ran through her mind:  There's no particular
merit in being nice to one's fellow man.  She had to treat the other villagers
decently, because otherwise she couldn't live there.  Even with Tomas, she was
OBLIGED to behave lovingly because she needed him.  We can never establish with
certainty what part of our relations with others is the result of our emotions
-- love, antipathy, charity, or malice -- and what part is predetermined by the
constant power play among individuals.
    True human goodness, in all its purity and freedom, can come to the fore
only when its recipient has no power.  Mankind's true moral test, its
fundamental test (which lies buried deeply from view), consists of its attitude
towards those who are at its mercy: animals.  And in this respect mankind has
suffered a fundamental debacle, a debacle so fundamental that all others stem
from it."
