mpi.comm.free {Rmpi}

MPI_Comm_free API

Description

mpi.comm.free deallocates a communicator so it points to MPI_COMM_NULL.

Usage

  mpi.comm.free(comm=1)

Arguments

comm

a communicator number

Details

When members associated with a communicator finish jobs or exit, they have to call mpi.comm.free to release resource so mpi.comm.size will return 0. If the comm was created from an intercommunicator by mpi.intercomm.merge, use mpi.comm.disconnect instead.

Value

1 if success. Otherwise 0.
