The talk introduces and extends an example related to some of the material from the tutorial itself. The slides from the talk are a little rough as the talk was somewhat ad-hoc: As session chair, I was confronted with a fairly last-minute cancellation and a 15 minute hole, and thought this would make a good little talk. It does show a nice trick for using littler with Open MPI (via snow) under the powerful slurm resource manager and batch/queue engine.
