Subject: [OMPI users] MPI_Comm_spawn query
From: Blesson Varghese (b.varghese_at_[hidden])
Date: 2009-09-22 08:20:43



I am fairly new to MPI.I have a few queries regarding spawning processes
that I am listing below:

a. How can processes send data to a spawned process?

b. Can any process (that is not a parent process) send data to a
spawned process?

c. Can MPI_Send or MPI_Recv be used to communicate with a spawned

d. Would it be possible in MPI to tell which processor of a cluster a
process should be spawned?


Looking forward to your reply. Would much appreciate if you could please
include code snippets for the same.


Many thanks and best regards,
