The approach to support the P&M multithreaded program execution model on workstation cluster

This paper presents the approach to support the P&M (Pipelining and Multithreading) program execution model on workstation cluster. The inter-node pipeline of communication and computation on workstation cluster is aimed to be constructed. The multithreaded program execution model employs both the incoming message handler and outgoing message handler to draw the distinction between real computation and communication. Low overhead communication is supported by the proposed communication protocol. The logical organization of one P&M node is developed which aims to support communication and computation by separate units. We further describe the P&M C language and the compilation technique. Emulation of the SPARC workstation based P&M platform convinces us that improved overall performance can be achieved, and more demanding applications can be feasibly solved by the P and M approach.
