A Graph and Mesh Partitioning and Sparse Matrix Ordering Program


ParMETIS is a program designed to compute graph and mesh partitionings in parallel as well as fill-reducing orderings for sparse matrices. The program provides a variety of different algorithms to compute such partitionings and orderings and is ideal for large-scale numerical computations and simulations.

Using ParMETIS on RCC Resources

ParMETIS requires the GNU OpenMPI module to access the main executable. To run ParMETIS, simply type the following commands:

module load gnu-openmpi
parmetis [ARGS]

There are numerous arguments that go into a ParMETIS run along with several required inputs. ParMETIS, however, is usually used in its API format. In order to run in either mode, please refer to the main website which contains a PDF usage manual.
