Re: HPL low performance result.

Sure you can use mpitb for benchmarking. I have a few academic papers that do just this, see below. The MPITB site has additional references. On Pelican, after setting up the cluster,  if you open a terminal, enter octave, and type "parallel_performance" you'll get some results that could be used to make a simple benchmark.

I strongly encourage you to see the MPITB page for a broader perspective - my own work is biased towards certain types of models and is certainly not representative of the general nature of applications of MPITB for Octave. I only cite the papers as examples that can give clues about how things can be done.
