The rm key.sah commands will make the current unit start from the

Thanks Roy, although that script runs only at power up, i went ahead and
took out those remove commands. That didnt cause any problems unlike
another suggestion to change the 17 to -17 . That caused major problems
to where the keyboard seemed to be connected to an old 110 baud modem.
It would not appear that the linux client is designed for smp
processing. Here is a rack of dual athlons we are working with
http://tinyurl.com/2eut6 all are running RH9 linux as the enterprise
edition of RH9 costs too much (hope SCO does not read this NG). I tried
out the linux version of seti but it seems to be worse off then the
windows version command line.
Beemer Biker,
I understand the the script only runs at power up. In its original form,
it threw away both the part complete WU every powerup. Thats two a day if
you switch off at night.
You need to do some bench marks with one and two instances of S@H running.
S@H is memory bandwidth intensive. Maybe a Dual PIII doesn't have the
bandwidth to support two processors.
You did build your kernel with SMP support I suppose? top should show CPU0
and CPU1 separately.

Computer users fall into two groups:-
Those that do backups
Those that have never had a hard drive fail
I don't know what your problem is, but, PIII's Do have the band width to
support two Processors, and older versions of Red Hat Linux SMP and run two
instances of SETI just fine.
