== Introduction ==
WIth most perl binaries compiled with a version of GCC that [https://gcc.gnu.org/projects/gomp/ supports OpenMP] in some form, it make a lot of sense to explore the use of OpenMP with Perl programs - and to make it much easier. This is where the Perl+OpenMP Project comes into play. The following page is really meant to be an overview of what is possible and the resources available to those interested in such efforts.

==== See Also ====
See main project site, https://github.com/Perl-OpenMP/ for more information.

== Quick Start ==
#!/usr/bin/env perl
use strict;
use warnings;

use OpenMP;

use Inline (
C => 'DATA',
with => qw/OpenMP::Simple/,
);

my $omp = OpenMP->new;

for my $want_num_threads ( 1 .. 8 ) {
$omp->env->omp_num_threads($want_num_threads);

$omp->env->assert_omp_environment; # (optional) validates %ENV

# call parallelized C function
my $got_num_threads = _check_num_threads();

printf "%0d threads spawned in ".
"the OpenMP runtime, expecting %0d\n",
$got_num_threads, $want_num_threads;

Alternate Compiler Support

This section will cover using Perl+OpenMP on compilers other than GCC. The trick is to adapt `Alien::OpenMP` to support other compilers that can be used to compile `perl` and also support OpenMP.
