[Networkit] Use of NetworKit in a Torque / PBS scheduling environment

Thank you Chris! This is exactly what I needed to learn. I hadn't realized
that it required shared-memory parallelism. Our center does have a
machine <http://www.carc.unm.edu/systems-software/systems.html>, 1 node, 64
cores (32+32), 256 GB shared memory. The center has an excellent
applications team and the NetworKit has excellent documentation, so I'm
guessing they'll be able to get it up and running for us.

Thank you again!

> arbitrary shell commands. NetworKit is a Python module that works with any
> Python interpreter. So if the system has Python installed, just submit a
> call to a Python script. If you have to do without Python, an executable
> written in C++ and linked against the NetworKit core library is also an
> option.
