  Yes, when I noticed that block of code several years ago. Looks like it would be easy to switch to long int but sadly this include is misleading about the simplicity, turns out this typedef beasty is not used throughout the source code consistently. I sent email about the 64 bit int at that time and got back the response "in a few months". Note that his non-MPI codes may fully support the 64 bit (I'm guessing that is where the $ is so is all he cares about). That was like two years ago.  I consider Parmetis orphaned, not maintained, hence in the HPC world, dead.
