Hmm, the docs don't seem to be all that enlightening. Here is another way.<div>init_node is called for every node in the run method of a starcluster plugin</div><div>as well as in the on_add_node method of the plugin. HTH.</div>

I've been digging through SGE/OGS docs for the last hour or so trying to<br>
sort out the easiest way to enforce a one job per host restriction, does<br>
anyone have a suggestion on how to do this? My hosts are coming up with<br>
8 slots, so I tried launching with -l slots=8 but it complained about<br>
wanting me to use parallel environments which looks even more complicated..<br>
<br>
Thanks,<br>
