NAME

LSF::JobManager - submit and wait for a set of LSF Jobs

SYNOPSIS

use LSF RaiseError => 0, PrintError => 1, PrintOutput => 0;
use LSF::JobManager;

my $m = LSF::JobManager->new(-q=>'small');

my $job = $m->submit("echo hello");
$m->submit("echo world");

for my $job ($m->jobs){
    $job->top;
}

$m->wait_all_children;
print "All children have completed!\n";

for ($m->jobs_with_status('EXIT') ){
    print "Job with id $_ exited non zero\n";
}

DESCRIPTION

LSF::JobManager provides a simple mechanism to submit a set of command lines to the LSF Batch system and then wait for them all to finish in a blocking (efficient) manner. Additionally, the LSF Batch system can be polled for jobs of particular status and those jobs are returned as LSF::Job objects; This is an inefficient way to wait for all jobs to complete but can be used to determine which jobs have a particular status.

INHERITS FROM

LSF

CONSTRUCTOR

new ( [ ARGS ] )

$manager = LSF::JobManager->new(-q=>'small' ,-m=>'mymachine');

Creates a new LSF::JobManager object.

Any parameters are used as defaults passed to the submit method.

METHODS

$manager->submit( [ [ ARGS ] ], [CMD] )

Submits a command line to LSF. This is a wrapper around the LSF::Job->submit call. The required argument is the command line to submit. Optional arguments override the defaults given to new. The submitted LSF::Job object is returned on success, otherwise undef is returned, $? and $@ set. See LSF::Job

$manager->wait_all_children()

Waits for all previously submitted LSF Jobs to complete in a blocking manner

$manager->jobs_with_status( [ [ STATUS_FLAGS ] ] )

Returns an array of jobs matching the given status flags (see LSF documentation) The default flag is 'EXIT', returning an array of LSF::Job objects representing command lines that exited non zero.

$manager->params()

Returns an array of the parameters that were passed to new

$manager->jobs()

Returns an array of the submitted LSF::Job objects.

HISTORY

The LSF::Batch module on cpan didn't compile easily on all platforms i wanted. The LSF API didn't seem very perlish either. As a quick fix I knocked these modules together which wrap the LSF command line interface. It was enough for my simple usage. Hopefully they work in a much more perly manner.
