Parallel::Runner Description
An object to manage running things in parallel processes There are several other modules to do this, you probably want one of them. The Parallel::Runner module exists as a super specialized parallel task manager. You create the object with a proces limit and callbacks for what to do while waiting for a free process slot, as well as a callback for what a process shoudl do just before exiting.You must explicetly call $runner->finish() when you are done. If the runner is destroyed before it's children are finished a warning will be generated and your child processes will be killed, by force if necessary.If you specify a maximum of 1 then no forking will occur, and run() will block until the coderef returns. You can force a fork by providing a boolean true value as the second argument to run(), this will force the runner to fork before running the coderef, however run() will still block until it the child exits.SYNOPSYS #!/usr/bin/perl use strict; use warnings; use Parallel::Runner; my $runner = Parallel::Runner->new(4); $runner->run( sub { ... } ); $runner->run( sub { ... } ); $runner->run( sub { ... } ); $runner->run( sub { ... } ); # This will block until one of the previous 4 finishes $runner->run( sub { ... } ); # Do not forget this. $runner->finish; Requirements: · Perl
