Fast file systems are critical for high-performance scientific computing, since many scientific applications have tremendous I/O requirements [MK91]. Many parallel supercomputers have only recently obtained fully parallel I/O architectures and file systems which are necessary for scalable I/O performance. Scalability aside, I show here that many systems lack sufficient absolute performance.
