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.
