"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I would suppose, if by trend you mean testing, development and the such, then using it to compute Asynchronous Cryptography would be a start, having 2 CPU's encrypt/decrypt a string within nanoseconds of each other.

Other than that I'm not too sure.
The recent trend in multicore cpus on a single chip are a form of parallel processing.  Clock speeds ran into physical limitations, so the other way to increase computation power is to put more cpus in a chip.  Quad cores are commonplace, and eight cores are probably just around the corner.
