I/O Performance of X-Y Routing in 2-D Meshes under Various Node-to-Disk Assignments

Abstract

High-performance parallel computers with 2-D mesh topologies axe beginning to be used as media-on-demand (MOD) servers. Multimedia data such as audio and video are stored on disks and the server needs to serve as many clients as possible, while satisfying the data requests of the clients in a timely fashion. Different patterns of mesh nodes-to-disk assignments emerge over time as the requests from clients are served, which affect the I/O performance. This paper studies the performance of I/O transfers in a 2-D mesh using X-Y routing under various node-to-disk assignments. The transfers are done using wormhole routing. The data transfers under various node-to-disk assignments are simulated and the results are presented.
