I thought I was working on a parallel machine :)
If you're using message passing on a dedicated interconnection network, a
beowulf system is clearly an MIMD machine as is the original intention.
Though, you could use a beowulf class supercomputer for high availability,
etc. which is not in the interest of parallel programming.
A parallel computer is not necessarily a shared memory (or even SMP which is
not the same thing) machine, as a matter of fact beowulf is all about
constructing an open and affordable MIMD platform.
On the other hand, the boundary between distributed and parallel research is
rapidly narrowing. There are a lot of systems which could be described as
