{lang}[foss/2025b] numba-cuda v0.20.0 w/ CUDA 12.9.1 by Thyre · Pull Request #24081 · easybuilders/easybuild-easyconfigs

Thyre · 2025-10-01T14:49:50Z

(created using eb --new-pr)

Requires:

{lib}[gfbf/2025b] CUDA-Python v12.9.2 w/ CUDA 12.9.1 #24080
{tools}[GCCcore/14.3.0] filecheck-python v1.0.3 #24077
{perf,tools}[GCCcore/14.3.0,gfbf/2025b] ml_dtypes v0.5.3, opt-einsum v3.4.0 #24076
enhance PythonPackage & PythonBundle easyblock to consider $EBPYTHONPREFIXES for test installs and path configuration files easybuild-easyblocks#3953

This EasyConfig adds modern CUDA support to the numba installation. The CUDA module in numba itself is pretty much dead, and will not properly work with the latest CUDA & NVIDIA drivers anymore. Instead, users are advised to use the numba-cuda package instead.

Installing numba-cuda has several additional dependencies. In addition, numba-cuda tries to override numba.cuda with a .pth file. While this typically works in a venv or a user/site-wide installation, this breaks with EasyBuild due to .pth files being ignored with PYTHONPATH. See here for more information.

To get this to work, we add a sitecustomize.py file in the installation directory which adds it to the site dirs. This lets Python pick up the .pth file again. The functionality is checked in the sanity check.

The test step will fail one test on systems where not much GPU memory is present. I can confirm that <4GB is certainly not enough, maybe even more is needed.

Hm, the test worked. Now we're failing the sanity check...

Argh, PythonBundle implements exactly the same code as PythonPackage, so the code to check for .pth files isn't run because it's using the PythonBundle one.

Need to adapt the PR a bit more...
