mpi_isend/4¶

mpi_isend(+ Data,+ Dest,+ Tag,- Handle)*

Non blocking communication predicate. The message in Data, with tag Tag, is sent whenever possible to the processor with rank Dest. An Handle to the message is returned to be used to check for the status of the message, using the mpi_wait or mpi_test predicates. Until mpi_wait is called, the memory allocated for the buffer containing the message is not released.
