I would include DSM, DFS, etc., as parallel computing tools, but I certainly wouldn't call them a "true 'parallel cluster'". Many current supercomputers are logically equivalent to a cluster of workstations with high speed interconnect, where tasks in a program communicate by passing messages (e.g. MPI). In my research for high performance computing, I develop the most efficient algorithms which dictate use of message passing, rather than virtual shared memory, for performance. This category should be inclusive -- *ANY* tools (above and beyond standard OS and networking infrastructure) which enable multiple CPUs to cooperate together to solve a computational problem. -david -- David A.
