The Steering Library was developed in part through DOE grant DE-FG05-95ER25266 (Partnerships in Computational Science ) which was administered through the Mathematical and Computer Sciences Department (MICS) to develop general purpose software tools for Computational Grand Challenge Problems. An initial design of this library was laid out by PICS personnel, particularly Dr. Joseph Pasciak, in Fall 1994 based on a previous prototype code, developed at Texas A&M which used the IPX library for message passing and permitted a non-interrupt tracking of array variables distributed by processor. The library in its current form was delivered to the Oak Ridge public groundwater repository in August 1995. Along with the library were the latex documentation, man pages, frequently asked questions, and 3 example programs on its use. In Spring 1996 we instrumented both Fortran, C, and Fortan/C coupled flow and transport codes with the library and the graphical user interface G3D. In Fall of 1996, the library was ported to MPI and the wavelet-based 3D data compression modules were added in Spring 1997.
