%T Throughput of Existing Multiprocessor File Systems (An Informal Study) %A David Kotz %R Technical Report PCS-TR93-190 %I Dartmouth College, Computer Science %C Hanover, NH %D 1993 %U http://www.cs.dartmouth.edu/reports/TR93-190.ps.Z %X Fast file systems are critical for high-performance scientific computing, since many scientific applications have tremendous I/O requirements. 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. I do this by surveying the performance reported in the literature, summarized in an informal table.
