Description:
PARMETIS is an MPI-based parallel library that implements a variety of
algorithms for partitioning and repartitioning
unstructured graphs and for computing fill-reducing orderings of sparse
matrices. PARMETIS is particularly suited for
parallel numerical simulations involving large unstructured meshes. In this
type of computation, PARMETIS dramati-
cally reduces the time spent in communication by computing mesh decompositions
such that the numbers of interface
elements are minimized.
The algorithms in PARMETIS are based on the multilevel partitioning and
fill-reducing ordering algorithms that are
implemented in the widely-used serial package METIS. However, PARMETIS extends
the functionality provided by
METIS and includes routines that are especially suited for parallel
computations and large-scale numerical simulations.
In particular, PARMETIS provides the following functionality:
• Partition unstructured graphs and meshes.
• Repartition graphs that correspond to adaptively refined meshes.
• Partition graphs for multi-phase and multi-physics simulations.
• Improve the quality of existing partitionings.
• Compute fill-reducing orderings for sparse direct factorization.
• Construct the dual graphs of meshes

Notes.
- This package is for EPEL6/7 and Fedora.
- Althought ParMetis provides Metis source, it has been patched to use the
'metis' library already packaged on Fedora.
- In this package I tried to compile ParMetis with 64-bit integers (against
Metis64), however I can't complete all related tests which look exhaust all
memory. Needs investigation.
