How to set affinity of a process

[Zakirasafi]

Dear all

I want to permanently assign different cores to 2 different processes. I mean when I will execute process one it always must execute on core 1 and the 2nd process always execute on core2. How i will do this by set affinity.

Thanks and Regards,

Based on a 30 second google search, and a quick ssh session to a linux machine:
taskset

Yeah, I already used the taskset command but through taskset command when I execute the program for the 2nd time the core has been changed. Everytime the code is changing when the program is execute. I want to permanently assign a specific core to a specific process.

Add the taskset command to the ossec-control sxript.

$ ps -eo psr , pid // pid is process id

i want to assign core 1 to process 1350

 I have written the following command

$taskset -c 1 -p 1350 (I want that core is permanently assigned to process 1350)

But this core 1 is not permanently assigined to process 1350.

If the process is using different cores after setting it to use a
specific core, you would probably have to talk to your distribution to
find out what is going on.
This doesn't sound like an OSSEC problem.
