ShARC Parallel Environments

The available parallel environments for ShARC only (Bessemer only has the SMP environment which is set by default) can be found below:

ShARC 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.
