Pelops-distributed is a Python library providing matrix-free linear algebra and optimization on distributed systems. As much as numpy and scipy lie at the core of the parent project PyLops, PyLops-distributed heavily builds on top of Dask, a Python library for distributed computing. Doing so, linear operators can be distributed across several processes on a single node or even across multiple nodes. Their forward and adjoint are first lazily built as directed acyclic graphs and evaluated only when requested by the user (or automatically within one of our solvers).
