# NAME Linux::CPUAffinity - set and get a process's CPU affinity mask # SYNOPSIS use Linux::CPUAffinity; # get affinity of this process my $cpus = Linux::CPUAffinity->get(0); # eg: [0, 1, 2, 3] # other process my $cpus = Linux::CPUAffinity->get($pid); # set affinity of this process Linux::CPUAffinity->set(0 => [0,1]); # other process Linux::CPUAffinity->set($pid => [0]); # utility method to get processors my $num = Linux::CPUAffinity->num_processors(); # DESCRIPTION Linux::CPUAffinity is a wrapper module for Linux system call sched\_getaffinity(2) and sched\_setaffinity(2). This module is only available on GNU/Linux. # METHODS - $cpus = $class->get($pid) Get the CPU affinity mask of the process. - $class->set($pid, $cpus :ArrayRef\[Int\]) Set the CPU affinity mask of the process. - $num = $class->num\_processors() Get the number of processors currently online (available). # LICENSE Copyright (C) Jiro Nishiguchi.
