Introduction

Pacific HiTech and COSMIC, NASA's official software repository and center for technology transfer, have teamed up to bring you source code from the US space program. The NASA Engineering Source Code series represents the first release of the NASA software archives on CD-ROM. These programs have been in actual use in designing and implementing key parts of America's space program, including the Apollo space craft, flights to Mars, and the Space Shuttle.

Most of the programs are written in Fortran, with a few in C, Pascal, Lisp and BASIC. Some of the programs have been implemented on specific computer architectures and will need modification to be used on other platforms. Although several of these were written over 10 years ago, the algorithms embedded in the programs should be as valid now as when they were first put into use.

Interface

We have provided an html interface to help you navigate the CD-ROM. It includes a search function for finding key words included in the abstracts of programs. The search function is a Java applet that is still in beta testing, and may not work with all browsers or platforms.

CD-ROM Contents

The top-level directory of this CD-ROM contains the following files and directories.

• programs: the source code for the programs
• abstracts: html abstracts for the programs for the entire series
• clustor: distributed computing program (see section below)
• images: gifs for the html interface
• search: Java applet files for searching via the html interface

• readme.txt plain text version of this file
• readme.html html version of this file
• program_index.html listing of the programs

Clustor: by Active Tools

As a bonus, we have included a pre-release version of Clustor, a state-of-the-art distributed computing interface from Active Tools, Inc. This program allows you to run multiple copies of a program with varied input data on a network of PCs, workstations or supercomputers. Clustor will prove particularly useful for simulation programs and other engineering applications in which the goal is to obtain optimal values or to test results for a wide range of input data. Active Tools can be reached at: www.activetools.com
