Introduction

LoadLeveler is a job management system. The idea is that given a network of CPU and storage resources, you should simply be able to specify a job you'd like to run, and leave it to LoadLeveler to find the appropriate resources to run the job on, and then to execute and supervise the job, while you can lay back, twitch your thumbs and watch the blinkenlights.

It is not only for your convenience, as a user, that job management systems are deployed at supercomputer centres and often even in smaller computing laboratories or departments. Job management systems ensure that resources are used optimally and that users don't step on each other's toes.

LoadLeveler serves as a job scheduler and provides additional facilities for building, submitting, and processing jobs in a distributed computing environment. It runs on the SP, but can be installed on nearly all desktop machines, MPI farms, even on mainframes. It interacts with NQS (Network Queuing System), and supports submit-only machines too.

LoadLeveler documentation can be found on the

OVPIT AFS cell WWW page
or in
/afs/ovpit.indiana.edu/common/www/htdocs/gustav/SP-docs/LoadL
On the SP itself you'll find it in
/usr/lpp/LoadL/postscript
