Method Detail

Start

public void Start()
           throws MPIException

Activate a persistent communication request. Java binding of the MPI operation MPI_START. The communication is completed by using the request in one of the wait or test operations. On successful completion the request becomes inactive again. It can be reactivated by a further call to Start.

Startall

public static void Startall(Prequest[] array_of_request)
                     throws MPIException

Activate a list of communication requests.

array_of_requests

array of requests

Java binding of the MPI operation MPI_STARTALL.
