Using a +movie sequel pun for the name is a double tribute to George Marsaglia, whose +"Diehard battery of tests" of random number generators has enjoyed years of +enduring usefulness as a test suite. + +The dieharder suite is more than just the diehard tests cleaned up and given a +pretty GPL'd source face in native C: tests from the Statistical Test Suite +(STS) developed by the National Institute for Standards and Technology (NIST) +are being incorporated, as are new tests developed by rgb. Where possible, +tests are parametrized and controllable so that failure, at least, is +unambiguous. + +A further design goal is to provide some indication of *why* a generator fails +a test, where such information can be extracted during the test process and +placed in usable form. For example, the bit-distribution tests should +(eventually) be able to display the actual histogram for the different bit +n-tuplets. + +Dieharder is by design extensible. It is intended to be the "Swiss army knife +of random number test suites", or if you prefer, "the last suite you'll ever +ware" for testing random numbers. + +WWW: http://www.phy.duke.edu/~rgb/General/dieharder.php |
