The fastest, most powerful machine to solve a problem today.
A supercomputer is one that is only one generation behind what you really need.

HPC is a fairly generic term though. It does not have to be parallel. An exceptionally large, or parallel database server can also be called HPC, although some will call it High Throughput Computing (HTC).
I would consider just about anything with more than 4 processors HPC. Including a 16-way Itanium2 or a 32p SGI or an 8 processor Xeon cluster or a 33,000 processor vector machine. I would even include a single desktop equipped with several FPGA's.
The term "Beowulf" is slightly more specific in that it requires a cluster of commodity machines running an OpenSource operating system. It could be either HPC or HTC.
A dual Xeon workstation does not quite cut it though...
