I have not investigated really deeply, but matlab, at least the version
I tried, had the choice between multi-core and mono-core (at runtime).
Personally, I have not been really impressed by the speed enhancement:
nothing scientific, but I tried it on several of my old matlab scripts
(I rarely use matlab since I am using numpy), and for some things it was
a bit faster, for some a bit slower. But the multi-core support was said
to be experimental for that version (it was not enabled by default for
