1/*
2 * Sample code for the DIS Update Stressmark
3 *
4 * This source code is the completely correct source code based on
5 * the example codes provided by Atlantic Aerospace Division, Titan
6 * Systems Corporation, 2000.
7 *
8 * If you just compile and generate the executables from this source
9 * code, this code would be enough. However, if you wish to get a complete
10 * understanding of this stressmark, it is strongly suggested that you
11 * read the Benchmark Analysis and Specifications Document Version 1.0
12 * before going on since the detailed comments are given in this documents.
13 * the comments are not repeated here.
