From 3d9f4dc2018ff9e2069b37a13ed89f3d190fdc91 Mon Sep 17 00:00:00 2001 From: Harwinder Date: Thu, 7 May 2026 22:22:21 -0400 Subject: [PATCH] =?UTF-8?q?Enable=20GPU=20scoring=20via=20CuPy=20=E2=80=94?= =?UTF-8?q?=20RTX=204070=20SUPER=20confirmed=206.3x=20speedup?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Install nvidia pip packages for CUDA 12 runtime DLLs (no full toolkit needed): nvidia-cuda-nvrtc-cu12, nvidia-cuda-runtime-cu12, nvidia-curand-cu12, nvidia-cublas-cu12 Add _register_nvidia_dlls() in backtest_gpu.py that auto-discovers and registers nvidia package DLL directories (site-packages/nvidia/*/bin/) via os.add_dll_directory() before CuPy is imported. Suppresses the spurious "CUDA path could not be detected" warning from cupy._environment. Backend line now reads: CuPy 14.0.1 (RTX GPU) Benchmark: scoring pass on 100k bars — NumPy 1.1ms vs CuPy 0.18ms = 6.3x. Results are identical to CPU path (deterministic).
