## This patch sets up libmetis soname of libmetis
Patch0:  %{name}-libmetis.patch

## This patch sets up shared GKlib library 
Patch1:  %{name}-shared-GKlib.patch

## Specify the width (32 or 64 bits) of the elementary data type 
## used in METIS. This is controled by the IDXTYPEWIDTH
## constant.
## For now, on a 32 bit architecture you can only specify a width of 32, 
## whereas for a 64 bit architecture you can specify a width of either 
## 32 or 64 bits.
Patch2:  %{name}-width-datatype.patch

## This patch sets up GKREGEX, GKRAND, libsuffix options to the Makefiles 
Patch4:  %{name}-GKREGEX-GKRAND-LIBSUFFIX-fix.patch

%description
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.
