A HIGH-PERFORMANCE CLUSTER COMPUTING ENVIRONMENT BASED ON HYBRID SHARED-MEMORY MESSAGE-PASSING MODEL

We conducted research and development of Distributed Supercomputing En vironment (DSE) based on distributed shared memory model to serve as a cluster computing environment to provide parallel processing faciliti es. Shared memory model and message passing model are well-known typic al models of parallel processing. It is desired that hybrid programmin g environment will make the best use of the prominent features of both models. Consequently, we add a new message passing mechanism to prese nt DSE, and create a prototype called Hybrid DSE as a hybrid model bas ed cluster computing environment. In this paper, we describe the imple mentation of a message passing mechanism on DSE and performance evalua tion of Hybrid DSE.
