I have one very stupid question, but I want to be sure that I am right.
If you have 2 interconnected virtual machines running and let them
compute some problem in parallel (using message passing interface -
MPI), is it really a parallel computation? I mean, when the host machine
has only one

Thank you for your answers. It is as I thought. I tested performance of
2 VMs on one single core host computer, but as Stealth said, there has
been no increase in speed. I tried to parallely compute the
multiplication of two huge matrices, but the time spent on computation
was just the same as

That's because the way the multicore OS is designed. Basically, as far as
I know, the load is not shared in such a way that one application would run

We are talking here about VirtualBox, not about a hypervisor, so if you are
correct, I would be glad to see some documentation about this.
This has nothing to do with being a hypervisor or not. Just have a look
at the source code, it is freely

I mean if host computer has multiple cores - single VBox guest instance
will see ( and will be able to run multiple processes on them ) some of

Speaking of Christmas reminds me to wish you Merry Christmas. And many
thanks for bringing Virtualbox on Mac. This version 2.0 is really
good--I have replaced Parallels 3 (ie no more upgrade of
Parallels...). Peter
