This code has been modified to work with the latest version of Metis (5.0.2 as if 2012-05-22). All functions except for one (NodeBisect) currently work.
The following instructions worked on Ubuntu Linux (10.10) and OSX 10.7.
Download and extract the 5.0.2 version of metis.
wget http://glaros.dtc.umn.edu/gkhome/fetch/sw/metis/metis-5.0.2.tar.gz tar xzvf metis-5.0.2.tar.gz cd metis-5.0.2/
Configure metis for 64-bit integers. This step is only required for 64-bit versions of Matlab. We need to edit
#define IDXTYPEWIDTH 32to
#define IDXTYPEWIDTH 64. On my system, this change was to line 33.
Make sure you have a working version of
cmakeinstalled. On OSX 10.7, I used the homebrew port.
brew install cmake
make config make all
Download and compile metismex. It is critical that this is in a subdirectory of metis otherwise the relative paths won't work.
# in the metis-5.0.2 directory git clone git://github.com/dgleich/metismex.git cd metismex matlab -nodisplay >> make
Check that it works
>> A = blkdiag(ones(5),ones(5)); A(1,10) = 1; A(10,1) = 1; A(5,6) = 1; A(6,5) = 1; >> [p1,p2] = metispart(sparse(A)) p1 = 1 2 3 4 5 p2 = 6 7 8 9 10
