Add global MPI communicator and refactor some internals #1428

Closed sethrj closed 1 month ago

sethrj commented 1 month ago

This is in preparation for an "end run gather" and other possible synchronization points for multiprocess tallying using MPI in addition to OpenMP/CUDA. (See #261 ) I've adjusted the code to hide the dependence on MPI from downstream codes, and added a shared "comm_world()" as well as an MPI communicator that stays with the shared params.
