| Summary: Fast Splittable PRNG | |
Pure Haskell implementation of SplitMix described in Guy L. Steele, Jr., Doug Lea, and Christine H. Flood. 2014. Fast splittable pseudorandom number generators. In Proceedings of the 2014 ACM International Conference on Object Oriented Programming Systems Languages & Applications (OOPSLA '14). ACM, New York, NY, USA, 453-472. DOI: <https://doi.org/10.1145/2660193.2660195> The paper describes a new algorithm /SplitMix/ for /splittable/ pseudorandom number generator that is quite fast: 9 64 bit arithmetic/logical operations per 64 bits generated. /SplitMix/ is tested with two standard statistical test suites (DieHarder and TestU01, this implementation only using the former) and it appears to be adequate for "everyday" use, such as Monte Carlo algorithms and randomized data structures where speed is important. In particular, it __should not be used for cryptographic or security applications__, because generated sequences of pseudorandom values are too predictable (the mixing functions are easily inverted, and two successive outputs suffice to reconstruct the internal state).

[#] 0.1.0.3
- Fix oops bugs in 0.1.0.2
- It's lowercase `windows.h`.
I blame Microsoft docs for using capital case `Windows.h` in the docs.

- accidental `shiftL` vs `shiftR` mixup for 32-bit generator initialization.
Doesn't affect Linux.
* Tue Oct 20 2020 psimons@suse.com
- Update splitmix to version 0.1.0.2.
[#] 0.1.0.2
- Drop `time` dependency in favour of handcoded initialization
- On Unix platforms we use `/dev/urandom` if it exists,
otherwise use `gettimeofday`, `clock` and `getpid`.
- On Windows we use `GetCurrentProcessID`, `GetCurrentThreadId()`,
`GetTickCount`, `GetSystemTime` and `QueryPerformanceCounter`.
- On GHCJS use `Math.random()`
- Using `time` is a fallback option (e.g. for Hugs).
