Performance evaluation of a massively parallel I/O subsystem

Published: 01 September 1994 Publication History

Abstract

Presented are the trace-driven simulation results of a study conducted to evaluate the performance of the internal parallel I/O subsystem of the Vulcan MPP architecture. The system sizes evaluated vary from 16 to 512 nodes. The results show that a compute node to I/O node ratio of four is the most cost effective for all system sizes, showing high scalability. Also, processor-to-processor communication effects are negligible for small message sizes and the greater the fraction of I/O reads, the better the I/O performance. Worse case I/O node placement is within 13% of more efficient placement strategies. Introducing parallelism into the internal I/O subsystem improves I/O performance significantly.
