<div class="content">
<p>This batch system is based on a database (MySql), a script
language
(Perl)
and a scalable administrative tool (component of Taktuk framework). It
is composed of modules which interact only with database and are
executed as independant programs. So formally, there are no API,
the system
is mainly specified by tables and fields of database, and theirs
meaning. This extreme approach allows to develop specific module in
easely
manner. Indeed, each module (as scheduler) can be developed in
desired
language which have a database access library.<br>
</p>
<p>Main features (version 1.0 and greater) :
</p>
<ul>
<li>Batch and Interactive jobs<br>
</li>
<li>Admission rules</li>
<li>Walltime<br>
</li>
<li>Matching of resources (job/node properties)<br>
</li>
<li>Hold and resume jobs</li>
<li>Multi-schedulers support (simple fifo and fifo with matching)<br>
</li>
<li>Multi-queues with priority</li>
<li>Best-effort queues (for exploiting idle resources)</li>
<li>Check compute nodes before launching<br>
</li>
<li>Epilogue/Prologue scripts<br>
</li>
<li>No Daemon on compute nodes<br>
</li>
<li>rsh and ssh as remote execution protocols (managed by Taktuk) <br>
</li>
<li>Dynamic insertion/deletion of compute node<br>
</li>
<li>Logging</li>
<li>Backfiling<br>
</li>
<li>First-Fit Scheduler with matching resource

Burn me on a CD.<br>
(Note : This CD was created for a mexican presentation)<br>
Suggested operations:<br>
<ol>
<ol>
<li>Click on Linux penguin on the desktop (it sets up the right
hostname if you want to test mpich)</li>
<li>Type "oarnodesetting -s Alive" (to add a node)</li>
<li>You can see some informations in Mozilla and Konqueror (home
page)</li>
<li>Test "oarsub -I", OAR must work<br>
</li>
