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