mpi_array.logging.get_root_logger¶

mpi_array.logging.get_root_logger(name, comm=None, root_rank=0)[source]¶

Returns a logging.Logger object with time-stamp, comm.Get_name() and comm.Get_rank() in the message. Logging output limited to the MPI rank specified by root_rank.

Parameters:	name (`str`) – Name of logger (note that the name of logger actually created will be `name + ".rank." + ("%04d" % comm.Get_rank())`). comm (`mpi4py.MPI.Comm`) – MPI communicator. Used for determining the rank of this process. If `None` uses `mpi4py.MPI.COMM_WORLD`. root_rank (`int`) – Logging output is limited to this rank, the returned `logging.Logger` objects on other ranks have a `logging.NullHandler`.
Return type:	`logging.Logger`
Returns:	Logger object.
