This document isn't meant to be a tutorial on the Perl scripting language so we will assume administrators modifying this module in the following documentation already have a functional knowledge of Perl's syntax. Good online resources for learning Perl can be found at {+}http://www.perl.com+ there also many good published books such as Learning Perl published by O'Reilly which can get a beginning developer started with Perl scripting. path_to_script

To create a new queuing algorithmcustom supervisor policy, the developer must create a Perl module with the following Perl functionssubroutines:

1. qb_init()
2. qb_approve_modify($oldjob, $newjob)
3. qb_approve_submit($job)
4. qb_calcstatus($subjobstatus, $agendastatus)
5. qb_sudo_admin($username, $job)

A function, if not defined will, automatically be overridden with the "Default Policy".
Example scripts can be found here:

• Linux: /usr/local/pfx/qube/examples/supervisor
• Windows: C:\Program Files\pfx\qube\examples\supervisor
• OS X: /Applications/pfx/qube/examples/supervisor

...

Here are details on each subroutine.
