Communication Modes

void Comm.bsend(Object buf, int offset, int count,
                Datatype datatype, int dest, int tag)
buf send buffer array
offset initial offset in send buffer
count number of items to send
datatype datatype of each item in send buffer
dest rank of destination
tag message tag



Send in buffered mode. Java binding of the MPI operation MPI_BSEND. Further comments as for send.

void Comm.ssend(Object buf, int offset, int count,
                Datatype datatype, int dest, int tag)
buf send buffer array
offset initial offset in send buffer
count number of items to send
datatype datatype of each item in send buffer
dest rank of destination
tag message tag



Send in synchronous mode. Java binding of the MPI operation MPI_SSEND. Further comments as for send.

void Comm.rsend(Object buf, int offset, int count,
                Datatype datatype, int dest, int tag)
buf send buffer array
offset initial offset in send buffer
count number of items to send
datatype datatype of each item in send buffer
dest rank of destination
tag message tag



Send in ready mode. Java binding of the MPI operation MPI_RSEND. Further comments as for send.
