-pe ib np Request np cores for parallel programs using MPI
-pe smp np Request np cores for parallel programs using OpenMP or threads
-l nodes=x[,ppn=y][,tpp=z] Specifies a job for parallel programs using MPI. Assigns whole compute nodes. x is the number of nodes, y is the number of processes per node, z is the number of threads per process. Recommended for parallel jobs. Not standard SGE option, added by University of Leeds.
