Exclusive Access File Library

An exclusive access file is a file which is generated and/or read by a single process of a distributed parallel application. Files are not shared between different processes. The library is an abstract high-performance file system which provides a common interface for a variety of architecture specific parallel storage systems. The library also makes available features like asynchronous input and output to Fortran. EAF's syntax is similar to the standard Unix C file operations, differences indicate new semantics or extended features available through EAF.
