===Learn to love tcsh===
One preliminary note is that GEOS-5 is, in many ways, a collection of csh/tcsh scripts. If things start going wrong, the answer can often be "change your shell to tcsh and try". Yes, it's not bash/fish/zsh, but it is what it is. I don't think it's entirely necessary for just this automated work, but it could happen.

The full benchmark run is a run of 5-days using a portable version of the GEOS-5 boundary conditions. This will use space and cores. For effective benchmarking of I/O, it's recommended to run on less congested than nobackup.
