Blackwell Notes

This repository targets a Blackwell-style workflow, but keeps the build configuration explicit because local toolchain support may differ across systems.

Build Guidance

• Prefer explicit architecture selection over hidden defaults.
• Use KERNEL_LAB_CUDA_ARCH=120 for Python-side build helpers when your local environment supports it.
• Use -DCMAKE_CUDA_ARCHITECTURES=120 with CMake for direct native builds.
• If your toolkit does not yet accept the exact architecture value you want, adjust the build flag rather than editing the kernels.

What To Watch On A New GPU Generation

• compiler support for the target architecture
• PyTorch wheel compatibility
• Triton support level
• driver/toolkit mismatch
• profiler tool compatibility

Treat environment validation as part of the lab, not as a one-time setup nuisance.
