perun.coordination.getHostRankDict(comm: perun.comm.Comm, hostname: str) → Dict[str, List[int]]

Return a dictionary with all the host names with each MPI rank in them.

Parameters:

• comm (Comm) – MPI Communicator

• hostname (str) – Local rank Hostname

Returns:

Global host and mpi ranks dictionary.

Return type:

Dict[str, List[int]]

perun.coordination.assignSensors(host_rank_dict: Dict[str, List[int]], g_available_sensors: List[Dict[str, Tuple]]) → List[Dict[str, Tuple]]

Parameters:

• host_rank_dict (Dict[str, List[int]]) – Host to rank mapping.

• g_available_sensors (List[Dict[str, Tuple]]) – List of available sensors for each backend for each rank.

Returns:

List with apointed backend and sensors for each MPI rank.

Return type:

List[Dict[str, Tuple]]
