Metis¶
Metis provides programs and a library for partitioning graphs and meshes.
Metis is available as a module on Apocrita.
Usage¶
To use the default installed version of the Metis programs and library,
simply load the metis module:
module load metis
Each of the Metis programs provides a help page, accessed with the -h
command-line option, for example
gpmetis -h
Metis provides an API with C, C++ and Fortran bindings. The module
provides the environment variable ${METIS} which can be used in specifying
search paths when compiling and linking programs:
gcc -o metis-test metis-test.c -I${METIS}/include -L${METIS}/lib -lmetis
The installed autoconf-archive contains a
macro AX_LIB_METIS which can be used in an Autoconf script to determine
the appropriate compiler flags for building against the Metis library.
Example jobs¶
The following job uses gpgmetis to partition a graph into two parts. The
input graph is given in the file 1.gph and the resulting output file will
be called 1.gph.part.2.
#!/bin/bash
#$ -cwd
#$ -j y
#$ -pe smp 1
#$ -l h_rt=1:0:0
#$ -l h_vmem=1G
module load metis
