Process’s afinity

Using schedutils, one can alter any process’s afinity by running a simple command: taskset. This way, it is feasible to change the GNU/Linux scheduler behaviour when it comes to running processes on a multi-core GNU/Linux box. For example, if we run any command directly, on a dual-core system, GNU/Linux […]
