  • floats v0.10.0: drop the max/min zero fallback and the moved sum/elementwise assembly by @​tannevaled in #​100

Full Changelog: v0.37.1...v0.37.2

v0.37.1

Compare Source

SumP runs on several cores again, with the bits of floats.SumPairwise (NumPy order) whatever the core count: it cuts the NumPy pairwise tree where NumPy cuts it and adds the subtrees back up the same tree (#​99). Results are unchanged from v0.37.0.

v0.37.0

Compare Source

K1 of the go-scikit performance campaign (go-scikit/roadmap#27): ndarray imports go-simd/floats v0.9.0.

Changed result: Sum (and mean, var, std built on it) is now NumPy's pairwise sum (floats.SumPairwise), bit-identical to np.sum of a contiguous 1-D float64 array on every architecture. It replaces lane-parallel sums whose last bits differed from NumPy's and between architectures; it is serial at every size.

Exp, Log and the correctly rounded float32 Exp/Log, and on amd64/arm64 the float64 add/sub/mul/div/sqrt/max/min/clip kernels, are go-simd/floats' (the AVX2 and NEON exp/log kernels written here moved down: #​94, #​95, #​96).

Several references per case

Step 1 of #​15. A case can now be measured against several reference implementations, not only one (usually SciPy). The design is in docs/design/multiref.md.

  • Case.Refs: each reference has an ID, a licence, a Timer and an Eval. Each gets its own verdict, and there is a headline verdict against the fastest side.
  • Rotated rounds: rounds follow a Williams (balanced Latin square) order, so every side runs equally often in each position and before or after each other side.
  • Accuracy per reference: the worst ulp against the same mpmath fixtures, with special-value disagreements counted apart.
  • Labels:
    • ahead requires Go to be at least as accurate as the reference, with no special-value disagreement and no lower coverage.
    • Otherwise a faster Go row reads faster-less-accurate.
    • A slower Go row reads behind or tradeoff.
  • Issues: a perf issue is drafted against any faster reference, including a less accurate one.
  • rbw1 worker protocol:
    • plain text, with a fixed function table: nothing read from the pipe is evaluated;
    • float64 input files verified by SHA-256, and a key whose last load did not verify cannot be timed or evaluated;
    • an untimed warm-up call before Calibrate, for JIT runtimes;
    • a single thread, checked against what the worker reports;
    • lines bounded to 4 KiB, a fuzzed parser, and a committed corpus.
  • Julia worker: Julia through a pinned pkgx binary. The version and the Manifest tree hashes are recorded in ref_versions.
  • Compiled-worker skeleton for C++ and Fortran: it reports threads_source, and assumed means unverified.
  • Schema 2 is written only when a case uses several references, and its reader is strict. Without them the output stays schema 1, byte for byte, pinned by golden files. An older refbench refuses a schema 2 file with a clear error.

Not yet (step 2):

  • The SciPy fixture column is not yet checked to reproduce bit for bit.
  • No R worker; R will run through Rscript only.
  • No CI lane runs the Julia worker. An opt-in test is available with REFBENCH_JULIA=1.

Smoke test (one core, 9 rounds, load 7.55–7.69), in ns per element and worst ulp against mpmath:

Go SpecialFunctions.jl Bessels.jl
Gamma 16.1 (0.50) 22.2 13.3
Kv 1201 (3.82) 185 41.7

Testing:

  • CI coverage now uses the covblocks gate, which names every uncovered block.
  • mutsweep v0.8.0 over the changed files, run on the final head:
    • default mode: 95 mutations, 68 caught, 0 caught by PANIC, 27 not mutants, 0 survived, 0 hung;
    • boundary mode: 29 mutations, 29 caught.
