Control degree of parallelism? #141

Closed pancetta closed 7 years ago

pancetta commented 7 years ago

Is there a way to actually control the degree of parallelism? In particular, how do I control and/or change the number of processes used for e.g. runStencil?

ehsantn commented 7 years ago

ParallelAccelerator uses OpenMP as the parallel backend. You can change the number of threads using OMP_NUM_THREADS environment variable. Changing it for a specific region of the function is not provided.

Thanks for your answer! Are there any plans to include distributed memory parallelism?

ehsantn commented 7 years ago

Not for ParallelAccelerator. HPAT provides distributed-memory parallelism for data analytics workloads.

I'm going through and cleaning up some old open issues. It looks like this was sufficiently answered, but if not, feel free to re-open. Thanks!
