Hello all -
I have an imaging app (uses ~500MB of memory) running on my DP264
(Linux 2.2.10) that seems to spend a lot of time context switching between
the processors (judging from xosview). If I change the priority of the
app, I can get it to stick on one processor longer before context
switching out (no big surprise there).
Would I see a _significant_ difference in performance if I was able to
force the app to stick to one CPU all of the time (forcing all other
processes to run on the second processor)? Could I get two copies of the
program running at the same time to stick to a single CPU and not context
switch? (runtime for the program is about 1 hour)
What is the best way to do this. 'nice -20 app' as root?
Thanks for your help -
