MPI Communicator wrapper

class fipy.solvers.trilinos.comms.parallelEpetraCommWrapper.ParallelEpetraCommWrapper¶

Bases: EpetraCommWrapper

MPI Communicator wrapper

Encapsulates capabilities needed for both Epetra and mpi4py.

MaxAll(obj)¶: return max across all processes

MinAll(obj)¶: return min across all processes

__getstate__()¶: Helper for pickle.

__repr__()¶: Return repr(self).

allgather(obj)¶

mpi4py allgather

Communicates copies of each sendobj to every rank in the comm, creating a rank-dimensional list of sendobj objects.

>>> m4count = self.mpi4py_comm.allgather(self.mpi4py_comm.Get_rank())
>>> from builtins import range
>>> for i in range(self.mpi4py_comm.Get_size()):
...     assert m4count[i] == i
