Performance Evaluation of a Parallel I/O Mechanism on a Massively Parallel Processing System JUMP-1

摘要

A massively parallel processing system JUMP-1 has been developed for high performance computing with an efficient cache coherent distributed shared memory on a large system with more than 1000 processors. Considering a total design policy, a scalable I/O mechanism is implemented on JUMP-1. Every cluster board of JUMP-1 has a serial link called "STAFF-Link" (Serial Transparent Asynchronous First-in First-out Link). Each channel of STAFF-Link is connected to an independent I/O unit, and works in parallel to obtain the scalable I/O bandwidth. In this paper, performance evaluation results of JUMP-1 I/O mechanism using real experimental systems are shown.
