Well what do you know. I run a site that uses SPM but we use Compaq Alpha=
s.
They beat the absolute
hell out of SPARCs. An fMRI image analysis that took 2 days on the Ultra =
II
based E6500 we now do in 6hrs. Knowing SPM my guess is that the system ma=
y
be swapping heavily. What's the spec of the system in terms of RAM, swap =
etc
and how are the data volumes mounted?

Actually We have Matlab on one of our SUN m/cs (ULTRA 80), preferable for
running one of our other programs (SPM) which requires matlab .=20
Starting matlab is fine . But when i start spm the CPU utilization increa=
ses
to abt 90% . The system bcomes dead slow .=20
Running vmstat shows a very high value of system calls

I think that means that thers a SYS bottleneck right ...

Corkscrew?=20

Sorry, couldn't resist.


What is the bottleneck and why do you think you have one? Usual solutions
are faster networks, more memory, bigger, faster disks, extra CPUS. Defin=
e
the problem a bit more.
