I have been thinking about the same problem, AFAIK at present this is 
not covered by the standard, SGE_TASK_ID is another such example.

However, I think this can easily be implemented by the various DRM 
vendors through a small utility/script, e.g.

drmaa -t	# return task id
drmaa -n	# return number of procs/slots
etc.

then, in your script you would have

	NP=`drmaa -n`
	mpirun -np $NP ...
