if you are using solaris, you can read up on resource management to do that

in solaris:

pbind -> for binding processes to one CPU

psrset -> creation and management of processor sets

i think you are looking for pbind (since you "only" have 2 CPUs).

get you process ids and use the following (bad example here, cause i have only one in my testmashine, but it still work Smilie ):

Code:
root@jumpy # psrinfo
0       on-line   since 01/27/2006 18:44:04
root@jumpy # pgrep cron
196
root@jumpy # pbind -b 0 196
process id 196: was not bound, now 0
root@jumpy # pbind -q
process id 196: 0
root@jumpy # pbind -u 196
process id 196: was 0, now not bound
root@jumpy #

When do you use pbind & when do you use resource manager?
