NAME
Smash::Utils::ClusterJob - General cluster job management module
SYNOPSIS
my %options = (
NAME => "testjob",
TYPE => "SGE",
MEMORY => 8000, #default 2000
WORKING_DIR => "mydir", #default cwd
EODIR => "eofiles", #default cwd
QUEUE => "all.q",
POLLING => 90, #default 60
CPUS => 4, #default 1
GROUP => 2, #default 1
LAMMPI => 1, #default 0
);
my $job = new Smash::Utils::ClusterJob(%options);
$job->submit_commands("echo first_command", "echo second_command", "echo last_command");
This will submit an array job with the three commands in the argument to submit_commands() to the queue called "all.q" in the SGE batch queuing system that is visible to the current host with the following options.
hard memory limit: 8000 MB
working directory: mydir/
error/output to : eofiles/
cpus allotted : 4
GROUP specifies if the commands should be grouped together at all. This is useful for very short jobs, where the cluster management overhead time is more than the actual run time of the job. In this example, commands are grouped in sets of two. Let's assume this was submitted as job array 100. Task 1 of Job 100 will execute the two lines:
echo first_command
echo second_command
Task 2 will execute the following line:
echo last_command
