Since you have only one generator, I'm afraid the || switch is not going to help.
It only parallelizes up to the number
of generators. I have not parallelized
the praxis method itself but there are
a few places we might be opportunistic
when it needs to evaluate the fitness
function two or three times to do its
basic line search. And I believe that
in some cases it can do more than
one line search at once such as when
it is calculating conjugate gradients.
The other direction is to parallelize an
individual run. I'm guessing you are using
a single cell and it is now possible to
split it into many pieces and harder to
arrange that the pieces are nearly the
same size. See

You may want my help on this and if you send me enough code to do a single run
I'll take a look at the degree to which multisplit is applicable. In any case, be aware that presently the -mpi argument means that there is no gui and you are running in batch mode. (the MultiRunFitter still works in this mode but you must start it using hoc code
since nothing will appear on your screen.)
