Yes, the docs for PBS are somewhat complex, but definitely worth the
effort to understand.
PBS is probably your best bet -- some creative use of pbsnodes and the
$PBS_NODEFILE environment variable may give you what you describe. For
example:
- Number of free nodes currently under PBS control (from any node):
pbsnodes -a | grep "state = free" | wc -l
- Number of nodes in a PBS job (from the within the job itself):
wc -l < $PBS_NODEFILE
Hope that helps.
