[mpich-discuss] New communicator from connect/accept primitives

[Francisco Javier García Blas]

Hello all,

I wondering the possibility of get a new inter-comunicator from N communicators, which are results from different calls of mpi_comm_connect or mpi_comm_accept.

My initial solution was first,  to get the group of each inter-communicator with mpi_comm_group, second, to join all the groups into one bigger and finally, to create a new communicator from the group with the mpi_comm_create primitive. 

Currently I am handling a pool of inter - communicators in order to keep the functionality. However this idea is not suitable for collective and MPI_ANY_SOURCE sends/recvs.

Exist another way to join all the inter-communicator into one?    

Any suggestion?

Best regards.
