NAME ^

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

VERSION ^

This document describes MCE::Util version 1.515

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 $ncpu = 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 adopted from Test::Smoke::SysInfo.
