NAME

HPC::Runner::Threads - Job submission using threads

VERSION

Version 0.01

SYNOPSIS

Use Parallel::ForkManager to run arbitrary bash commands

Attributes

twait

How frequently to test for a thread having exited the queue in seconds. Defaults to once every 60 seconds. If your jobs are very fast, you may want to decrease this number, or vice versa if they are very long.

threads

This uses Parallel::ForkManager to deploy the threads. If you wish to use something else you must redefine it here.

SUBROUTINES/METHODS

go

This is the main application. It starts the logging, build the threads, parses the file, runs the commands, and finishes logging.

parse_file_threads

Parse the file of commands and send each command off to the queue.

#TODO #Merge mce/threads subroutines

build_threads

This is the command to build the threads. To change this just add a build_threads method in your script.

    $self->threads->run_on_wait(
        sub {
            $self->log->debug("** Queue full. Waiting for one process to end ...");
        },
        $self->twait,
    );

or

    package Main;
    extends 'HPC::Runner::Threads';

    sub build_threads {

        $self->threads->run_on_wait(
            sub {
                $self->log->debug("** This is my custom message");
            },
            $self->twait,
        );
    }
