I think you're asking how long MPI_RECV will wait for a matching send,
right?
If so, MPI_RECV is a "blocking" receive, meaning that it will not
return until a matching send has been received and the user buffer is
loaded with the message. There is no timeout; it'll effectively block
forever until a matching message is received.
