Abstract

This paper discusses the benefits of incorporating a separate processor into a processor node of Massively Parallel Architectures to handle messages and proposes hardware solutions to provide atomicity between the main processor and the processor dedicated to handle messages. The proposed design is aimed at improving the performance by relegating the responsibility of handling messages to a separate processor. The hardware modifications are kept to a minimum in order not to disturb the original functionality of a modern RISC processor.
