EXECUBE-A New Architecture for Scaleable MPPs

The EXECUBE chip is a new single part type building block for MPP systems that scales seamlessly from a few chips (with a few hundred mips) to thousands of chips with petaop potential. Further, the chip architecture supports directly both SIMD and MIMD modes of processing, permitting not only the best of both current parallel computing modes but also new modes not possible with more conventional designs. This paper discusses the overall architecture of the EXECUBE chip, the new computational model it represents, some comparisons against the current state of the art, how it might be used for real applications, and some extrapolations into future developments.
