Abstract

The authors propose a library providing Unix file system support for highly parallel distributed-memory computers. CMMD I/O supports Unix I/O commands on the CM-5 supercomputer. The overall objective of the library is to provide the node level parallel programmer with routines for opening, reading, writing a file, and so forth. The default behavior mimics standard Unix running on each node; individual nodes can independently perform file system operations. New extensions to the standard Unix file descriptor semantics provide for co-operative parallel I/O. New functions provide access to very large (multi-gigabyte) files
