PFIO is the Parallel File I/O library.
The PFIO library provides a pair of highly optimized Fortran I/O routines for moving 32- and 64-bit data between memory and disk devices. Cray Floating Point data may also be converted on the fly to or from 32-bit IEEE or 64-bit Cray IEEE formats.
The PFIO_IEEE library includes a similar interface for the Cray Parallel Vector Platforms as well as a number of 32-bit IEEE and Cray 64-bit IEEE data conversion routines.
PFIO was written by D. C. O'Neal and R. Reddy, PSC Parallel Applications Group (oneal@psc.edu and rreddy@psc.edu).
Installed on the T3D/T3E and J90/C90.
