| Description | In Proceedings of International Parallel Processing Symposium The significant difference between the speeds of the I/O system (e.g. disks) and compute processors in parallel systems creates a bottleneck that lowers the performance of an application that does a considerable amount of disk accesses. A major portion of the compute processors' time is wasted on waiting for I/O to complete. This problem can be addressed to a certain extent, if the necessary data can be fetched from the disk before the I/O call to the disk is issued. Fetching data ahead of time, known as prefetching in a multiprocessor environment depends a great deal on the application's access pattern. The subject of this paper is implementation and performance evaluation of a prefetching prototype in a production parallel file system on the Intel Paragon. Specifically, this paper presents a) design and implementation of a prefetching strategy in the parallel file system and b) performance measurements and evaluation of the file system with and without prefetching. The prototype is d... |
