View-Oriented Parallel Programming is based on Distributed Shared Memory which is friendly and easy for programmers to use. It requires the programmer to divide shared data into views according to the memory access pattern of the parallel algorithm. One of the advantages of this programming style is that it offers the performance potential for the underlying Distributed Shared Memory system to optimize consistency maintenance. Also it allows the programmer to participate in performance optimization of a program through wise partitioning of the shared data into views. In this paper, we compare the performance of View- Oriented Parallel Programming against Message Passing Interface. Our experimental results demonstrate a performance gap between View-Oriented Parallel Programming and Message Passing Interface. The contributing overheads behind the performance gap are discussed and analyzed, which sheds much light on further performance improvement of View-Oriented Parallel Programming. Key Words: Distributed Shared Memory, View-based Consistency, View-Oriented Parallel Programming, Cluster Computing, Message Passing Interface
