pylops_mpi.MPIStackedLinearOperator#
- class pylops_mpi.MPIStackedLinearOperator(shape=None, dtype=None, base_comm=<mpi4py.MPI.Intracomm object>)[source]#
Stack of MPI-enabled PyLops Linear Operators
Common interface for performing matrix-vector products in distributed fashion for a stack of
pylops_mpi.MPILinearOperatoroperators.In practice, this class provides methods to perform matrix-vector and adjoint matrix-vector products on a stack of
pylops_mpi.MPILinearOperatoroperators, allowing the actual execution of each operator to be distributed, whilst dispatching the execution of the different operators in sequential order.Note
End users of pylops-mpi should not use this class directly but simply use operators that are already implemented as extensions of this class. This class is meant for developers only, it has to be used as the parent class of any new stacked operator developed within pylops-mpi.
