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.
