Design of a file system for a message-passing MIMD multiprocessor to be used for scientific computing. Separate I/O nodes from compute nodes; I/O nodes and disks are viewed as a data-staging area. File system runs on I/O nodes only. Files declustered by record, among physical partitions, each residing on a separate disk, and each separately growable. Then the user maps logical partitions, one per process, on the file at open time. These are designed to be two-dimensional, so that mapping arrays of various strides and contiguities, with records as the basic unit, is easy. Various consistency and atomicity requirements. File checkpointing, really snapshotting, is built in. No client caching, no redundancy for reliability. See also corbett:vesta2, corbett:vesta3, feitelson:pario.} }
