Submatrix Method

This repository contains a prototypic implementation of the submatrix method, used to approximately calculate inverse p-th roots of large sparse matrices, distributing the workload over many compute nodes using MPI.

Details about the method, its applicability in different applications and an evaluation of its performance and scalability can be found in our scientific publication:
