Línea de trabajo

Start with csrc/selective_scan/reverse_scan.cuh, where the three errors occur at lines 132 (cub::LaneId()) and 335 and 353 (cub::CTA_SYNC()), and with the hard-coded -gencode architectures in setup.py. Reproduce the build in a container on the 25.11 base image. Done means the extension compiles there, which likely requires updating the architecture list and replacing the removed CUB APIs. The fix belongs to the external varlen_mamba repo, so confirm with maintainers which project should receive it.

🐞 Describe the Bug

We cannot compile the varlen implementation of Mamba from https://github.com/jxiw/varlen_mamba in the new base image 25.11. setup.py hard-codes some cuda architectures which are no longer supported, which is easily fixable, but then I'm getting cpp compile errors, ex.
