BRL-CAD

Write program comparing performance of bn_randmt vs C++ random

The goal of this task is to create a simple little test program that compares the performance of BRL-CAD's merzenne twister random number generator (bn_randmt) with C++;s rand_mt implementation. Although there are usage examples all throughout the BRL-CAD codebase, you can find bn_randmt's API header in:

  • include/bn

Examples of C++'s are all over the web:

You should use bu_gettime() as a stopwatch timer: e.g., int64_t start = bu_gettime(); printf("elapsed is %lf\n", bu_gettime() - start);

Compare performance drawing random numbers. Do they match if you use the same or a nearby seed? You can use any build system you want (e.g., CMake) or rely on direct compilation, or just provide a compile-line that will work if we assume BRL-CAD is installed.

SUBMIT your program sourcecode with instructions on how to compile and run.
