pylops_mpi.MPILinearOperator

class pylops_mpi.MPILinearOperator(Op=None, shape=None, dtype=None, base_comm=<mpi4py.MPI.Intracomm object>)

Common interface for performing matrix-vector products in distributed fashion.

This class provides methods to perform matrix-vector product and adjoint matrix-vector products using MPI.

Note

End users of pylops-mpi should not use this class directly but simply use operators that are already implemented. This class is meant for developers only, it has to be used as the parent class of any new operator developed within pylops-mpi.

Parameters:

Oppylops.LinearOperator, optional

Linear Operator. Defaults to None.

shapetuple(int, int), optional

Shape of the MPI Linear Operator. Defaults to None.

dtypestr, optional

Type of elements in input array. Defaults to None.

base_commmpi4py.MPI.Comm, optional

MPI Base Communicator. Defaults to mpi4py.MPI.COMM_WORLD.

Methods

__init__([Op, shape, dtype, base_comm])
adjoint()	Adjoint MPI LinearOperator
conj()	Complex conjugate operator
dot(x)	Matrix Vector Multiplication
matvec(x)	Matrix-vector multiplication.
rmatvec(x)	Adjoint Matrix-vector multiplication.
transpose()	Transposition of MPI LinearOperator
