Abstract

Parallel execution of application programs on a multiprocessor system may lead to performance degradation if the workload of a parallel region is not large enough to amortize the overheads associated with the parallel execution. Furthermore, if too many processes are running on the system in a multiprogrammed environment, the performance of the parallel application may degrade due to resource contention. We propose a comprehensive dynamic processor allocation scheme that takes both program behavior and system load into consideration when dynamically allocating processors. We implemented this mechanism in the Java run-time system on Solaris to dynamically control the execution of parallel Java application programs. Performance results show the effectiveness of this scheme in dynamically adapting to the current execution environment and that it outperforms a conventional time-shared system.
