Abstract

The processor industry has reached the point where sequential improvements have plateaued and we are being flooded with parallel hardware we don't know how to utilise. An efficient, general-purpose and easy-touse parallel model is urgently needed to replace the von Neumann model. We introduce and discuss the selfmodifying dataflow graph, an unusual model of computation which combines the naturally parallel dataflow model with local graph transformations to eliminate the need for a global memory. We justify why it is a promising candidate.
