Abstract

Modern multicore processor technology can fairly easily deliver special accelerator processors dedicated to fast optimised execution of critical computational functions. Multi CMP (Chip Multi-Processor) systems can be composed as a set of dedicated and general purpose computational modules interconnected by a global data exchange network. The paper proposes special program scheduling algorithms for such systems. Dedicated CMP modules assumed in the paper are based on a new data communication model called communication on the fly. It enables strong reduction of inter---process and inter---core communication overheads for intensively shared data.
