cuda-pathfinder 1.6.0 Release notes#

Highlights#

  • find_nvidia_binary_utility() now probes configured binary directories directly instead of delegating to shutil.which, avoiding implicit current-working-directory lookup on Windows. If those locations miss, a new CTK-root canary fallback resolves cudart through the OS dynamic loader, derives its CUDA Toolkit root, and searches that root’s bin layout. With multiple visible toolkits, the result follows the cudart selected by the dynamic loader and may differ from the executable selected by a shell. (PR #2196)

  • Add dynamic-library loading and header discovery for the cuQuantum libraries cudensitymat, cupauliprop, cutensornet, custabilizer, and custatevec on Linux. (PR #2376)

  • Add dynamic-library loading support for cutensorMp on Linux, including preloading the packaged CUDA runtime in CUDA 12 wheel-only environments. (PR #2374)

  • Add Windows Arm64 discovery for cudla.dll, enabling load_nvidia_dynamic_lib("cudla") to find cuDLA in the CUDA Toolkit’s architecture-specific bin directories. (PR #2274)

Internal maintenance#

  • Clean up dead and misleading error-handling code in the Linux and Windows dynamic-library loaders; runtime behavior is unchanged. (PR #2239)
