[Discuss] How do I Set CPU affinity when running an application [RESOLVED]

[pw]

Hello,

I'd like to thank Lloyd Budd for kicking the hamster that
runs the wheel inside my brain.

Although I have been using 'taskset' for changing
the affinity of processes using the PID, I neglected to
note that you can also run applications (with arguments)
with taskset as well.I should have read the man page
again sooner... ~:|

It works.
