	Gather-scatter communication using MPI. More...

Modules
module	gs_mpi
	Defines MPI gather-scatter communication.

Functions/Subroutines
subroutine	gs_mpi::gs_mpi_init (this, send_pe, recv_pe)
	Initialise MPI based communication method See gs_comm.f90 for details.
subroutine	gs_mpi::gs_mpi_init_vec (this)
	Allocate the fused vector exchange buffers, sized for GS_VEC_NC components. Deferred to the first fused exchange, see gs_comm_t.
subroutine	gs_mpi::gs_mpi_free (this)
	Deallocate MPI based communication method.
subroutine	gs_mpi::gs_nbsend_mpi (this, u, n, tag, deps, strm)
	Post non-blocking send operations.
subroutine	gs_mpi::gs_nbrecv_mpi (this, tag)
	Post non-blocking receive operations.
subroutine	gs_mpi::gs_nbwait_mpi (this, u, n, op, strm)
	Wait for non-blocking operations.
subroutine	gs_mpi::gs_nbsend_vec_mpi (this, u, n, nc, tag, deps, strm)
	Post non-blocking sends for a fused nc-component exchange.
subroutine	gs_mpi::gs_nbrecv_vec_mpi (this, tag, nc)
	Post non-blocking receives for a fused nc-component exchange.
subroutine	gs_mpi::gs_nbwait_vec_mpi (this, u, n, nc, op, strm)
	Wait for a fused nc-component exchange and reduce each received slab.
