MSk - the package for a dense matrix approximation in the mosaic-skeleton format

P. 20–27.

Valiakhmetov B., Tyrtyshnikov E.

In this paper we present the package for approximation dense matrices in mosaic-skeleton format. It is flexible in terms of matrix appearance, ambient domain decomposition and approximation method. A user can choose default implemented methods or replace any of them with his own code without any compatibility issues. The package is extensible for any other block-independent approximation formats. MSk is written on C++ and supports parallel execution on shared and distributed memory with OpenMP, C++ threads and MPI standard.

Keywords: mosaic-skeleton method, hierarchical matrix, low-rank, matrix cross approximation
