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 threading 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 processor cores currently online. For example, a single chip quad-core processor returns four.
- max_socket
-
Returns the number of populated CPU sockets, if known, else the same number as max_physical. For example, a single chip quad-core processor returns one.
- 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.
