At the suggestion of Linas Vepstas on the Gnu Scientific Library (GSL) list,
|
|
this GPL'd suite of random number tests will be named "Dieharder". 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.
