Multiprocessor file system interfaces

Abstract

The difficulties faced when using the conventional (UNIX-like) interface in parallel applications are described. Ways to extend the conventional interface to provide convenient access to the file for parallel programs, while retaining the traditional interface for programs that have no need to explicitly parallel file access, are described. The interface includes a single naming scheme, a multiopen operation, local and global file pointers, mapped file pointers, logical records, multifiles, and logical coercion for backward compatibility.<>
