Short answer: Not possible. At least not what you are asking for.
If you used some sort of SSI-style clustering with *very* fast
inter-connects (10Gb Ethernet, Infiniband, etc...), with a lot of luck,
hard work, and man-hours it may be possible. Although, I'm not sure how
thread-friendly VMware Server is, or exactly how it will behave in that
kind of environment.
Beowulf style clusters require the program that is to be running on it
programmed in a certain way utilizing an MPI library. By far, the
most common High Performance Clusters utilize grid-style computing
(think SETI, cloud computing, etc...) where things are broken down into
tasks and organized to be run in discreet parts.
VMware's ESX clustering capabilities are *very* limited in this
regard (and also expensive), which it is really coordinating loads
across multiple ESX servers, that are usually pretty powerful
in-of-themselves, and not distributing the load of a single guest across
multiple physical machines.
I've spent a lot of time thinking about this very thing...
