MPI_Send(3OpenMPI)														MPI_Send(3OpenMPI)

NAME
MPI_Send - Performs a standard-mode blocking send. SYNTAX
C Syntax #include <mpi.h> int MPI_Send(void *buf, int count, MPI_Datatype datatype, int dest, int tag, MPI_Comm comm) Fortran Syntax INCLUDE 'mpif.h' MPI_SEND(BUF, COUNT, DATATYPE, DEST, TAG, COMM, IERROR) <type> BUF(*) INTEGER COUNT, DATATYPE, DEST, TAG, COMM, IERROR C++ Syntax #include <mpi.h> void Comm::Send(const void* buf, int count, const Datatype& datatype, int dest, int tag) const INPUT PARAMETERS
buf Initial address of send buffer (choice). count Number of elements send (nonnegative integer). datatype Datatype of each send buffer element (handle). dest Rank of destination (integer). tag Message tag (integer). comm Communicator (handle). OUTPUT PARAMETER
IERROR Fortran only: Error status (integer). DESCRIPTION
MPI_Send performs a standard-mode, blocking send. NOTE
This routine will block until the message is sent to the destination. For an in-depth explanation of the semantics of the standard-mode send, refer to the MPI-1 Standard. ERRORS
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ func- tions do not return errors. If the default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism will be used to throw an MPI:Exception object. Before the error value is returned, the current MPI error handler is called. By default, this error handler aborts the MPI job, except for I/O function errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error. SEE ALSO

NAME
MPI_Ssend_init - Builds a handle for a synchronous send. SYNTAX
C Syntax #include <mpi.h> int MPI_Ssend_init(void *buf, int count, MPI_Datatype datatype, int dest, int tag, MPI_Comm comm, MPI_Request *request) Fortran Syntax INCLUDE 'mpif.h' MPI_SSEND_INIT(BUF, COUNT, DATATYPE, DEST, TAG, COMM, REQUEST, IERROR) <type> BUF(*) INTEGER COUNT, DATATYPE, DEST, TAG, COMM, REQUEST, IERROR C++ Syntax #include <mpi.h> Prequest Comm::Ssend_init(const void* buf, int count, const Datatype& datatype, int dest, int tag) const INPUT PARAMETERS
buf Initial address of send buffer (choice). count Number of elements to send (integer). datatype Type of each element (handle). dest Rank of destination (integer). tag Message tag (integer). comm Communicator (handle). OUTPUT PARAMETERS
request Communication request (handle). IERROR Fortran only: Error status (integer). DESCRIPTION
Creates a persistent communication object for a synchronous mode send operation, and binds to it all the arguments of a send operation. A communication (send or receive) that uses a persistent request is initiated by the function MPI_Start. ERRORS
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ func- tions do not return errors. If the default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism will be used to throw an MPI:Exception object. Before the error value is returned, the current MPI error handler is called. By default, this error handler aborts the MPI job, except for I/O function errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be returned.
