Abstract
In this paper, we introduce a Java implementation of the Bulk Synchronous P arallel (BSP) model. JBSP (a Java-based BSP system) uses a two-daemon archi tecture which makes a clear separation Of the computation and communication involved in parallel programs. Java threads are used in the implementation of the JBSP system to realize User defined JBSP tasks as well as to carry out system activities. The JBSP library provides programmers with both expl icit message-passing and remote memory access communication methods. In add ition, a set of benchmark experiments was also carried out to compare the p erformance of JBSP with that of BSPlib. Results show that there is consider able overhead in communications in the Current implementation of JBSP due t o the use of Java's Object Serialization. It was also found that although B SPlib outperforms JBSP in all the cases, JBSP is more scalable in terms of the BSP machine-parameters. (C) 2001 Academic Press.
