[Jayesh Krishna]

Hi,
 Did you try MPI_Intercomm_merge() ?

Regards,
Jayesh

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


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.
