[mpich-discuss] MPI_Comm: Accept and connect comunicators

[Francisco Javier García Blas]

Hi all,

I am writing a simple test that use MPI_Comm_Accept/Connect primitives. 
What is the difference between using MPI_COMM_WORLD or MPI_COMM_SELF in 
this primitives?  The aim of the test consists of creating communicators 
to connect each of clients to all servers and vice versa.

Thanks a lot.
Javier
