source code

Instance Variables
	emptykvs self.emptykvs holds an empty KVS needed by map_once, map_on_rank_zero, read_files_reassemble, and read_file_by_segments.
	nprocs self.nprocs holds an nprocs of MPI.
	rank self.rank holds a rank of MPI.

Method Details

init(self, comm, info=None)
(Constructor)

source code

Makes a KMR context with a given MPI communicator (comm), which is used in succeeding operations. Info specifies its options by MPI_Info. Arguments of comm/info are passed as a long integer (assuming either an integer (int) or a pointer in C). It also accepts a string "dummy" or "world" as a comm argument.
