| 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).
BSD-3-Clause
* Tue Oct 03 2023 [email protected]
- Update splitmix to version 0.1.0.5.
Upstream has not updated the file "Changelog.md" since the last
release.
* Mon Nov 01 2021 [email protected]
- Update splitmix to version 0.1.0.4.
[#] 0.1.0.4
- Add TestU01 test-suite
* Thu Dec 17 2020 [email protected]
- disable %{ix86} build
* Fri Oct 23 2020 [email protected]
- Update splitmix to version 0.1.0.3.
[#] 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.
https://docs.microsoft.com/en-us/windows/win32/api/processthreadsapi/nf-processthreadsapi-getprocessid
- accidental `shiftL` vs `shiftR` mixup for 32-bit generator initialization.
Doesn't affect Linux.
* Tue Oct 20 2020 [email protected]
- 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).
* Tue Aug 18 2020 [email protected]
- Replace %setup -q with the more modern %autosetup macro.
* Fri Aug 07 2020 [email protected]
- Update splitmix to version 0.1.0.1.
[#] 0.1.0.1
- Add `INLINEABLE` pragmas to `bitmaskWithRejection*` functions
- Support GHC-9.0
* Tue Jul 07 2020 [email protected]
- Update splitmix to version 0.1.
[#] 0.1
- Drop `random` dependency unconditionally.

* Tue Jun 09 2020 [email protected]
- Update splitmix to version 0.0.5.
- Add `nextInteger`
- Use smaller range in `bitmaskWithRejection32` and `64`, when
upper bound is 2^n - 1. This changes generated values when they
were on the boundary.
* Thu Feb 27 2020 [email protected]
- Update splitmix to version 0.0.4.
- Add `bitmaskWithRejection32'` and `bitmaskWithRejection64'`
which generate numbers in closed range `[0, n]`.
- Unticked variants generate in closed-open range `[0, n)`.
* Fri Nov 08 2019 [email protected]
- Drop obsolete group attributes.
* Wed Jul 31 2019 [email protected]
- Update splitmix to version 0.0.3.
- Add `System.Random.SplitMix32` module
- Add `bitmaskWithRejection32` and `bitmaskWithRejection64` module
- Add `nextWord32`, `nextTwoWord32` and `nextFloat`
- Add `random` flag, dropping dependency on `random`
(breaks things, e.g. `QuickCheck`, when disabled).
* Thu Mar 28 2019 [email protected]
- Add splitmix at version 0.0.2.
