Generally, it's best to run 1 worker process per core, as the default is for
MDCS workers to run single-threaded (more precisely: with only a single
*computational* thread, there are plenty of other supporting threads). So, if
you have 2 8-core nodes, you could use up to 16 worker licences.

Cheers,

Edric.
