pylops_mpi.basicoperators.MPIStackedVStack

class pylops_mpi.basicoperators.MPIStackedVStack(ops, base_comm=<mpi4py.MPI.Intracomm object>, dtype=None)

MPI Stacked VStack Operator

Create a vertical stack of pylops_mpi.MPILinearOperator operators.

Parameters:

opslist

One or more pylops_mpi.MPILinearOperator to be vertically stacked.

Attributes:

shapetuple

Operator shape

Raises:

ValueError

If ops have different number of columns

Notes

An MPIStackedVStack is composed of N pylops_mpi.MPILinearOperator stacked vertically. These MPI operators will be applied sequentially, however distributed computations will be performed within each operator.
