Deprecation of CentOS 7 support

[jakirkham]

As of CUDA 12.4.0, CentOS 7 support is deprecated as noted in the CUDA 12.4.0 release notes. Have copied the relevant snippet below:

1.4.2. Deprecated Operating Systems

CUDA Toolkit 12.4 deprecates support for Red Hat Enterprise Linux 7 and CentOS 7. Support for these operating systems will be removed in an upcoming release.

Officially CUDA 12.5.0 and newer drop support for EL7; the NVIDIA 555 driver branch does not support the EL7 3.10 kernel, the minimum version changed to 4.15 kernel.

Thanks Kevin! 🙏

As we don't ship the driver in Conda, users are on their own to get it, which means they will encounter any errors installing or running the driver via the usual mechanisms

Think what is of most interest to conda-forge is GLIBC compatibility of binaries in these packages. Currently that has been GLIBC 2.17 (or older), which is consistent with EL7 compatibility. Having some insight on when this will change would be helpful for planning

Happy to discuss this more offline

To prepare for AlmaLinux 8 images, there are a couple CDTs we are using that are not available there. We have the following PRs to clean these up. They may need a bit of help to get across the line

• Use rdma-core package (instead of CDT) & add to linux_aarch64 libcufile-feedstock#14
• Replace CDTs with Conda packages & cleanup yum_requirements.txt nsight-compute-feedstock#32

Not seeing any other CDT usage in the CTK packages, but if I missed anything please add them to this issue so we can track them
