by

You need to use sched_setaffinity(2). For example, to run on CPUs 0 and 2 only: #define _GNU_SOURCE #include <sched.h> cpu_set_t mask; CPU_ZERO(&mask); CPU_SET(0, &mask); CPU_SET(2, &mask); int result = sched_setaffinity(0, sizeof(mask), &mask); (0 for the first parameter means the current process, supply a PID if it’s some other process you want to control).

It blocks till the result is ready. This method chops the iterable into a number of chunks which it submits to the process pool as … Read more
