How to exclusively assign process to a core?

nottix

Hi All,

i need to _exclusively_ assign a process to a core on SMP system.

I should do that with a kernel module not in user-mode.

I tried CGroup, but it doesn't assign exclusively a process to core.

I want this:

4 cores, 20 processes.

Process 1 -> Core 1

Processes 2-19 -> Core 2-4

Every time a new process has been created it doesn't must be assigned to Core 1.

Thanks

I found a blog post about a function called CPU affinity that allows oyu to assign processes to specific cores. Please look over the blog post and comments at http://www.cyberciti.biz/tips/setting-processor-affinity-certain-task-or-process.html and please post back if you have any issues or to report success.
