Summary
CI built against CUDA 13.2.1 and 12.8.1. It now builds against 13.4.1, the latest release, and 12.9.2, the last 12.x release.
The 12.9 row was commented out for NVIDIA/cccl#4967, a CCCL macro that overflowed on a long list of architectures. That row had no
cuda_arch, so mkmf-cu built every architecture in its list. The 12.9.2 row takes the architectures the 12.8.1 row used, and 12.8.1 is dropped. No code branches on a CUDA version between 12.4 and 13.0, so 12.6.3 and 12.9.2 cover the 12.x range, and 12.9.2 still builds sm_120.ðĪ Generated with Claude Code
