I think this is a question for the development community, so I'm moving it to 
the developers list.

For those unfamiliar with "parfor" is a parallel for loop.

        http://www.mathworks.com/help/toolbox/distcomp/parfor.html

There are other Matlab commands which may be used to enable parallel 
computation.

Might some of this be parsed by Octave and run on a single thread?
