Message-passing controller for a shared-memory multiprocessor

Although message-passing is a versatile communication paradigm in the multiprocessing area (AthSe88), a pure message-passing mechanism via special communication channels is inefficient. Shared-memory multiprocessor systems are usually much cheaper and efficient. Conventional approaches tend to implement message-passing on top of shared-memory architectures using a pure software approach. Even with special techniques (FinHe88), the performance of such systems is still worse than simple shared-memory communication systems. In this paper, the authors present a hardware approach and new message-passing mechanisms that the pure software approach does not support. Such an approach is quite cost effective. The resulting system is suitable for studying concurrent software, and scientific computations.
