Detailed Description

The collectives of a distributed run.

Both callables empty = a single rank (serial, or np = 1 without them). sumAll(data, n) replaces data[0..n) by its global sum on every rank (MPI_Allreduce SUM); broadcast(data, bytes) copies rank 0's bytes to every rank (MPI_Bcast). solver/anderson_mpi.hpp builds one from an MPI_Comm.
