Results of empirical testing #2
Description
This is not an issue - this is just to record the results of testing the RANLUXPP output with PractRand
TL;DR: RANLUXPP has passed PractRand test. Tested up to 32TiB of the output.
Results of testing with PractRand-RNG_test version 0.95
./ranluxpp_test 6 outputs 9 (nine) 64-bit unsigned integers at each RANLUX step. See code
Tested on Intel i7-8650U CPU @ 1.90GHz with 32GiB RAM.
