High-performance INMOS Transputers linked together form a
multicomputer system. The Transputer is designed to efficiently
execute OCCAM, a high-level parallel programming language. In
OCCAM, synchronous message-passing is the only means of interprocess
communication. A brief description of the Transputer and OCCAM will
be given in the first half of this seminar.
Despite its many good features, the Transputer system has two
major drawbacks. First, each Transputer node has only four external
communication links. When inter-node communication is heavy, these
links become the bottleneck. Second, it does not support
asynchronous communication; a feature which is favorable for a
certain class of application. To solve these problems a
communication system is proposed. The proposed design provides
asynchronous message-passing communication, message store-and-
forward, buffering and routing through the Transputer network. The
communication system's architecture will be presented. Schemes to
evaluate the performance of the communication system will also be
discussed.
