[mpich-discuss] get several children of mpi_comm_spawn into one intracommunicator

[Jayesh Krishna]

Hi,
 Did you try MPI_Intercomm_merge() after spawn and using the resulting intracommunicator for further spawns?

Regards,
Jayesh

Hi, 
my program is a client/server application when the client connects to the server than the server starts to use mpi_comm_spawn to launch other clients(clients are launched, one after other not in the same time, when conditions are satisfied) and i need all clients and the server to be in the same intracommunicator. so, does anybody knows some tricks to do that? 
regards, 
Toufik
