Introduction to Schedule::Load

Please note this tool is no longer being actively supported.

Written by Wilson Snyder <wsnyder@wsnyder.org>.

Summary

Schedule::Load provides the ability to determine the best CPU across many machines, and to determine running jobs across many machines in a network. It can also act as a free LSF or batch scheduler.

# Get per-host or per top process information
use Schedule::Load::Hosts;
foreach my $host ($hosts->hosts) {
    printf $host->hostname " is on our network\n";
}
