Does the MPI standard implement the request-reply communication pattern?
Reading about MPI I found that there are point-to-point routines like:
- Synchronous send
- Blocking send / blocking receive
- Non-blocking send /non-blocking receive
- Buffered send
- Combined send/receive
- "Ready" send
Maybe a developer can implement the request-reply communication pattern using these routines, but it seems that MPI does not directly implement it.
Edit: For clarifying purposes the request-reply (request-response) is a message exchange pattern in which a requestor sends a request message to a replier system which receives and processes the request, ultimately returning a message in response. This is a simple, but powerful messaging pattern which allows two applications to have a two-way conversation with one another over a channel. This pattern is especially common in client–server architectures. It may be synchronous or asynchronous.
