All of the code described here was developed the GNU C/C++ compiler and has been tested on a variety of Unix platforms that support the 2.72 or later versions of the GNU compiler (e.g. Silicon Graphics (IRIX 5.3, 6.1), SUN (SUN-OS 4.13), and Hewlett-Packard (HP-UX 9.05)). These packages and example applications are available at http://ndbserver.rutgers.edu/software/ or ftp://ndbserver.rutgers.edu/pub/programs/. Reference documentation is available in both Postscript and HTML format at this site.
