mpi test calls in sequential to improve latency hiding #201

Closed reguly closed 3 years ago

gihanmudalige commented 3 years ago

Do we need to merge this in. Is this important for the OP2-Hydra work ?

reguly commented 3 years ago

@gihanmudalige this now includes partial halo exhcnages, enabled with the OP_PARTIAL_EXCHANGES runtime flag, and the MPI_Test calls, enabled by the OP_TEST_FREQ=XXX runtime flag, which enables test calls every XXX iterations. Fortran + C MPI sequential codegens are updated for test calls Partial halo exchanges only involve changes in the backend

Oh and it would be good to remember the flags for activating these in the docs.
