NAME

MCE::Util - Public and private utility functions for Many-core Engine

VERSION

This document describes MCE::Util version 1.499_005

SYNOPSIS

use MCE::Util;

DESCRIPTION

This is a utility module for MCE. Nothing is exported by default. Exportable is get_ncpu.

get_ncpu()

Returns the number of available (online/active/enabled) CPUs.

my $cpus = MCE::Util::get_ncpu();

Specifying 'auto' for max_workers calls MCE::Util::get_ncpu automatically.

use MCE;

my $mce = MCE->new(
  max_workers => 'auto-1',        ## MCE::Util::get_ncpu() - 1
  max_workers => 'auto+3',        ## MCE::Util::get_ncpu() + 3
  max_workers => 'auto',          ## MCE::Util::get_ncpu()
);

ACKNOWLEDGEMENTS

The portable code for detecting the number of processors was borrowed from Test::Smoke::SysInfo.
