Disk I/O in High-Performance Computing Systems

There exists an increasing disparity between the performance of high-performance computers and disk I/O systems. This divergence in performance signifies that the I/O system will become an increasing bottleneck in future computer systems. With such a bottleneck, a program's execution time on these systems could approach the associated file access time in the limiting case. We review the evolution of I/O architectures and characterize the access patterns of requests to those I/O systems. We apply this information to investigate the I/O performance of a multiple disk system in a multiprocessor system.
