Processors(3)

NAME
Unix::Processors - Interface to processor (CPU) information

SYNOPSIS
  use Unix::Processors;

  my $procs = new Unix::Processors;
  print "There are ", $procs->max_online, " CPUs at ", $procs->max_clock, "\n";
  if ($procs->max_online != $procs->max_physical) {
      print "Hyperthreading between ",$procs->max_physical," physical CPUs.\n";
  }
  (my $FORMAT =   "%2s  %-8s     %4s    \n") =~ s/\s\s+/ /g;
  printf($FORMAT, "#", "STATE", "CLOCK",  "TYPE", );
  foreach my $proc (@{$procs->processors}) {
      printf ($FORMAT, $proc->id, $proc->state, $proc->clock, $proc->type);
  }

DESCRIPTION
This package provides accessors to per-processor (CPU) information. The object is obtained with the Unix::Processors::processors call. the operating system in a OS independent manner.

max_online
    Return number of processors currently online. On hyperthreaded Linux systems, this indicates the maximum number of simultaneous threads that may execute; see max_physical for the real physical CPU count.

max_physical
    Return number of physical processors currently online.

max_clock
    Return the maximum clock speed across all online processors. Not all OSes support this call.

processors
    Return an array of processor references. See the Unix::Processors::Info manual page. Not all OSes support this call.
