Enim, Before going into all these efforts to implement a new function, let me describe what is there already and that you can use to achieve something similar. It will not be exactly what you describe, because changing a particular collective algorithm dynamically on a communicator might is not as

[OMPI devel] MPI_Bcast algorithm

Hi, I want to create broadcast function which allow me to select algorithm in application layer. For example : MPI_Bcast_alg(void *buffer, int count, MPI_Datatype datatype, int root, MPI_Comm comm, int alg) Same arguments as MPI_Bcast() and plus algorithm's id. *coll_tune_bcast_decision.c* fil
