About Batchelor

This web application is powered by Batchelor, a batch job queue manager written in PHP.

Using a batch queue manager allows jobs with long run times to be submitted to the web server and scheduled for later execution by its batch queue. Users (submitters) can monitor the state of their submitted jobs (pending, running or finished) and later download the result from the queue view.
