METIS - Serial Graph Partitioning and Fill-reducing Matrix Ordering

METIS

METIS is a set of serial programs for partitioning graphs, partitioning finite element meshes, and producing fill reducing orderings for sparse matrices. The algorithms implemented in METIS are based on the multilevel recursive-bisection, multilevel k-way, and multi-constraint partitioning schemes developed in our lab.

Downloading METIS

METIS uses Git submodules to manage external dependencies. Hence, please specify the --recursive option while cloning the repo as follow:

git clone --recursive https://github.com/KarypisLab/METIS.git

Building standalone METIS binaries and library

To build METIS you can follow the instructions below:

Dependencies

General dependencies for building slim are: gcc, cmake, build-essential. In Ubuntu systems these can be obtained from the apt package manager (e.g., apt-get install cmake, etc)

sudo apt-get install build-essential
sudo apt-get install cmake

Building and installing METIS

METIS is primarily configured by passing options to make config. For example:

make config shared=1 cc=gcc prefix=~/local
make install

will configure metis to be built as a shared library using GCC and then install the binaries, header files, and libraries at

~/local/bin
~/local/include
~/local/lib

directories, respectively.

Common configuration options are:

cc=[compiler]   - The C compiler to use [default is determined by CMake]
shared=1        - Build a shared library instead of a static one [off by default]
prefix=[PATH]   - Set the installation prefix [~/local by default]
i64=1           - Sets to 64 bits the width of the datatype that will store information
                  about the vertices and their adjacency lists. 
r64=1           - Sets to 64 bits the width of the datatype that will store information 
                  about floating point numbers.

Advanced debugging related options:

gdb=1           - Build with support for GDB [off by default]
debug=1         - Enable debugging support [off by default]
assert=1        - Enable asserts [off by default]
assert2=1       - Enable very expensive asserts [off by default]

Other make commands

make uninstall
     Removes all files installed by 'make install'.

make clean
     Removes all object files but retains the configuration options.

make distclean
     Performs clean and completely removes the build directory.
