2 | * Sample code for the DIS Transitive 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. | ||
14 | * | ||
15 | * CHANGELOG: | ||
16 | * Joshua Bakita, 05/30/2020: Fixed out-of-bounds randInt call | ||
