Editing Portal:Perl+OpenMP

== 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 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;
 }
  
 __DATA__
 __C__
  
 /* C function parallelized with OpenMP */
 int _check_num_threads() {
   int ret = 0;
     
   PerlOMP_GETENV_BASIC
    
   #pragma omp parallel
   {
     #pragma omp single
     ret = omp_get_num_threads();
   }
  
   return ret;
 }

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.
