ShARC/SGE Parallel Environments

The available SGE parallel environments (for ShARC only) can be found below:

ShARC SGE Parallel Environments Table

Parallel Environment Name <env>

Parallel Environment description

smp

Symmetric multiprocessing or ‘Shared Memory Parallel’ environment. Limited to a single node and therefore 16 cores on a normal ShARC node.

openmp

A ‘Shared Memory Parallel’ environment supporting OpenMP execution. Limited to a single node and therefore 16 cores on a normal ShARC node.

mpi

Message Passing interface. Can use as many nodes or cores as desired.

mpi-rsh

The same as the mpi parallel environment but configured to use RSH instead of SSH for certain software like ANSYS.

Other parallel environments not mentioned do exist for specific purposes. Those who require these will be informed directly or via signposting in other documentation.

A current list of environments on ShARC can be generated using the qconf -spl command.
