In the realm of parallel processing, several parallel file systems with interesting ideas have emerged [Kot94, DSE88, DS89, FBD94, CBF93, TBC 94] These systems are often geared toward matrix operations, and a number of descriptors to encapsulate typical access patterns are described [Kot94, CBF93] SPIFFI [FBD94] implements global shared file pointers of varying flavors (multiple clients access the ....

Scalable Concurrency Control for Parallel File Systems - Moyer, Sunderam (1995) (5 citations) (Correct)
....concurrency control that does not require either explicit synchronization between the processes of a parallel application, or cooperation among the I O node daemons. At the same time, the mechanism is general enough to be used in conjunction with collective operations and disk directed I O [Kot94], two complementary techniques for the efficient transfer of noncontiguous data to each process participating in a coordinated file operation. 5 Experimental Results PIOUS is a parallel file system that employs volatile transactions to provide sequential consistency of access. Performance results ....

Tuning STARFISH - Kotz (1996) (2 citations) Self-citation (Kotz) (Correct)
....gather scatter block transfer. We also present results of the experiments driving the tuning effort. 1 Introduction STARFISH is a parallel file system simulator, based on the Proteus simulator [BDCW91] It was originally developed by the author for research into the concept of disk directed I O [Kot94a, Kot94b, PEK96, Kot95b, KC95, Kot95c, Kot95a]. In the course of preparing a more complete paper about disk directed I O [Kot96] we made several modifications to both of the parallel file systems supported by STARFISH ( traditional caching, which we now call the traditional parallel file system, and disk directed I O ) This report ....

Dynamic File-Access Characteristics of a Production Parallel .. - Kotz, Nieuwejaar (1994) (44 citations) Self-citation (Kotz) (Correct)
....effectively increasing the request size, lowering overhead, and perhaps eliminating the need for compute node buffers. Strided requests are available in some file system interfaces [CFPB93, DdR92, Kot93] For some applications, collective I O requests can lead to even better performance [Kot94] Dependence on Intel CFS. We caution that some of our results may be specific to workloads on Intel CFS file systems, or to NASA Ames s workload (computational fluid dynamics) Although the exact numbers are workload specific, we believe that the conclusions above are applicable to scientific ....
