The Berkeley Motifs and an Integral Parallel Architecture
Abstract. The Integral Parallel Architecture (IPA) developed by
BrightScale is a low-power & low-area one-chip solution to solve intense
computational problems using data-parallel, time-parallel and
speculative-parallel mechanisms. BrightScale technology is presented and
analyzed from the point of view of each of the 13 computational motifs proposed
in The Berkeley's View [1]. IPA emerges from the Stephen Kleene's computational
model of the partial recursive functions [3] as the simplest parallel
architecture, a good starting point for a true science of parallel computation.
We briefly investigate how such an elementary parallel architecture performs,
for the main computational motifs, in solving the problems of programmability,
portability, flexibility, data movement between computational cells, and between
cells and the main memory.
