The level of parallelism Jean is talking about is possible without
parallelizing the interpreter (which would be a lot of work). This is
possible so long as all the parallel code is implemented in C or C++,
and not in Octave.
It should also be possible to make an octave forge package that
provides parallel implementations of functions like eig using PETSEC
or SLEPC. It looks like there are already packages in octave forge
that provide access to mpi in Octave (parallel and openmpi_ext).
