Introduction UMFPACK is Unsymmetric MultiFrontal direct solver for sparse matrices developed by Prof Timothy A. Davis: http://www.cise.ufl.edu/research/sparse/umfpack/ In this document I will explain how to modify configurations files in the UMFPACK distribution in order to compile it directly with Microsoft Visual C by using GNU Make under Cygwin. For simplicity I have limited myself to [...]

METIS is written in C by using int and when one uses a solver on a 64-bit system that employs 8-byte integers this must be changed. Recently I have compiled MUMPS with -i8 and this was exactly this case. The newest version of METIS seems have an option to compile METIS with long but it [...]
When solving a system of linear equations with a sparse matrix by the direct method, it is crucial to run a reordering algorithm to reduce fill-in in the factor. Without this, it just does not work. METIS is a reordering algorithm developed by Prof Karypis at the University of Minnesota – Karypis Lab. It is [...]
