Users expect immediate access to data while increasing the load on the system. Many database software systems in place today are reaching performance limits due to I/O constraints. Parallel I/O is an alternative to serial I/O systems that can offer a partial solution this problem of scalability. In this paper we evaluate the use of parallel I/O in a heterogeneous computing environment for performance impact on database applications. We created a database system that uses parallel database servers and parallel I/O. PVM and PIOUS provide the parallel services. We then ran a suite of benchmark tests including various parallel configurations and number of clients. When we tested the database using both parallel I/O and parallel database servers, total benchmark run time of eight clients was only slightly longer than that of a single client. When we removed either parallel I/O or parallel database servers from the test, the run times increased incrementally with additional clients. The resulting analysis shows that, in certain configurations, the combination of parallel I/O and parallel database servers makes the database system more scalable than its serial I/O counterparts. | |
