Submitting POE Interactive Jobs to LoadLeveler

Before you can submit jobs to LoadLeveler, please add the following path to your PATH: /usr/lpp/LoadL/full/bin, for man pages please add the man path to MANPATH: /usr/lpp/LoadL/full/man . All loadleverler commands are under /usr/lpp/LoadL/full/bin.

$ poe ./main -rmpool 1 -nodes 2 -tasks_per_node 2

(always specify "-rmpool 1" as this instructs loadleveler which nodes are can be used to execute this job)
