hypercube machines (e.g., nCube) |
Hypercube architectures typically utilise off-the-shelf processors coupled via proprietary networks (both hardware and message-passing software); |
IBM SPx |
Utilising standard RS6000-type processors coupled via a very high speed, high bandwidth switch networking architecture, the nodes within an SPx system use a special very low-level message-passing library for the lowest-level (i.e., most efficient, fastest) mechanism for communicating with one another. |
