how to run two unix/linux programs on two different cpu cores

Hi folks,

I want to know how to run two unix programs on two different cpu cores on a 2-core or 4-core or 8-core CPU machine? Extending this how would i run four and eight unix programs on 4-core and 8-core machine respectively?

If this can be done, how to know which program is assigned to which core? I mean how would you collect statistics about the running program?

Thanks a lot for looking at my thread.


Kind Regards,

Usually, there is no need to run them on specific cores. Just run them simultaneously and they'll use time on whatever CPU is available and the OS deems appropriate. It will do multiprocessing without further effort on your part.

If you really need to do so, install schedutils. Then you can do

taskset -c 1 -p 13545 to fix certain process ID's to certain processors.

These are instructions for Linux. It will be different for any other UNIX or UNIX-like.
