Setting Processor Affinity in application

grubby23 · 01-28-2010, 08:22 AM

Hi,

Let us assume I have a very simple program.I wonder if there is any
possibility that I can set in this application an affinity so that
the processor binds it to core 2 for instance.

Code:

int main(int argc, char *argv[]){
        int j

        // SET_AFFINITY(CORE 2) ... IS THIS POSSIBLE here?
        for(j = 0; j < 10; j++)

        {

          printf('test\n');
        }  
}

Is this possible to do in an application that runs than under root? Or
is this just possible after the application started with using the taskset tool?

many thanks

Assuming you're using Linux, take a look to sched_setaffinity
