This shows my ability to dive into a new project and help fix linking and api issues. With the release of METIS 5.0, the support for 64-bit indices was added. This provided a promising future for direct matrix solvers such as SuiteSparse and MUMPS to solve bigger systems on a single machine but without each package adding support for this, it would be of no use to anyone. Therefore, I went ahead and did the work so that each solver package could take advantage of this feature. The patch for MUMPS was submitted here and the patch for SuiteSparse is on its homepage (search for my name).
Futhermore, I improved the packaging and installation for METIS / ParMETIS which can be seen below.
