These are some preliminary instructions for the 4.0 release of ParMetis. 1. You need to have a C compiler that supports the C99 standard. Gcc works just fine, but I have not tested it on many other architectures (any feedback/patches for different architectures are welcomed) 2. You need to have GNU make and CMake 2.8 (http://www.cmake.org/) installed. 3. Edit the file metis/include/metis.h and specify the width (32 or 64 bits) of the elementary data type used in ParMetis (and 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. 4. At the top of ParMetis' directory execute 'make' and follow the instructions. make config (usually without options) make
