tandem-ml

OCaml implementation of Tandem8x32. It produces the stream of the specification bit for bit. Fills run a vendored tandem-c through C stubs, with a pure OCaml fallback in Tandem.Pure.

• API: the generator, its draws and fills, Tandem.State and parallel use.
• Design: the C fills, bounded integers, normals and exponentials.
• Tests: what the suites check, the fixtures, and what CI runs.
• Performance: Apple M4 figures against Random.State.

Install

git clone git@github.com:tandem-rng/tandem-ml && cd tandem-ml
opam install . --deps-only --with-test && dune build

Needs OCaml 5.3 or newer and a C compiler. The fills run a vendored copy of tandem-c at 121db59. Not published to opam.

AI assistance

This port was written with the help of large language models under human direction. The design and the specification are human work, as is much of the Julia implementation. The code is tested bit for bit against every vector of the specification and against long stream dumps from the Julia implementation, and every value must match. The output does not depend on who or what wrote the code.
