ozaki op• Data kinds: none → table (an op determined by its arguments alone — it takes no image or data input)
• Call: import fullseye as fs; fs.ledger.fp64_emulation_probe() (to call the implementation directly, import ozakimm; ozakimm.fp64_emulation_probe(); from the registry, opsdrive.get("fp64_emulation_probe"))
Returns a table showing whether cuBLAS FP64 emulation (CUDA 13.0 Update 2 or later) is usable on this machine.
> The detailed description below is the original text — the summary and the headings are translated.
例外を出さない: GPU・CUDA・cuBLAS 13 が無ければ available=False と理由を返す(重い依存は持たない。ctypes でライブラリを開いて版を読むだけ)。返り: available(bool)、rows(候補ごとの library・path・loaded・ cublas_version・emulation_api(cublasSetEmulationStrategy があるか)・gpu(ハンドルを作れたか)・ reason)、how(有効にする方法)、note。
有効にする方法は opt-in: math mode CUBLAS_FP64_EMULATED_FIXEDPOINT_MATH、またはコードを変えずに CUBLAS_EMULATE_DOUBLE_PRECISION=1。cuBLAS の文書はエミュレーション中はビット単位の再現の保証が外れると書く —— 再現が要るなら matmul_reproducible。
