Abstract
An inter-processor communication approach is applicable to a message passing pattern called iterative exchange. In such patterns, two processors exchange messages, then perform a computation, and then this process is repeated. If two sets of send and receive buffers are used, then it is possible to guarantee that a receive buffer on the receiver's side is always available to receive the message. A message passing system controls which buffers are used for sending and receiving. These buffers are registered beforehand, thereby avoiding repeated registration at the time messages are sent. The sender is initially informed of all the possible receive buffers that the receiver will use, and the sender then uses these receive buffers alternately. Examples of this approach can avoid the use of multiple-step rendezvous protocols, memory copies, and memory registrations when a message needs to be sent.
