You do the exact same thing. You don't have to provide a hostfile (if
you do, LAM will simply ignore it). So your pbs script should look
something like:
---pbs.script---
cd $PBS_O_WORKDIR
lamboot -v
mpirun C application
lamhalt -v
---pbs.script---
The lamhalt isn't strictly necessary, but I would leave it in just in
case. Every now and then, PBS does something stupid and doesn't clean
up everyone very nicely. And it's always nice to have the complete
session output in your PBS output files :).
Hope this helps,
Brian
