Subject: [OMPI users] multithreaded jobs

Hi all,

The FAQ has excellent entries on how to schedule on a SGE cluster non-MPI
jobs, yet only simple jobs are exemplified. But wnat about jobs that can be
run in multithreaded mode, say specifying option -t number_of_threads? In
other words, consider a command an esample qsub script:
..........
#$ -pe openmpi 16
..........

mpirun -np $NSLOTS my_program -t 16 > out_file

Will that launch a program to run in 16 threads (as desired) or will this
launch 16 instances of a program wiith each instance trying to run in 16
threads (certainly not desired)?
