source: https://github.com/NVIDIA/cutlass.git
vendored: 2026-09-04

Only include/ (cutlass + cute headers, header-only) and LICENSE.txt are
vendored -- not the full upstream repo (examples/, test/, tools/, media/,
python/ are not needed to consume CUTLASS as a header-only dependency and
would multiply this directory's size many times over for no benefit here).
Flat-vendored as a plain committed directory, not a git submodule, for the
same reason third_party/ggml is vendored this way rather than as a
submodule: a submodule pointing at a large public or private repo adds a
real clone-ergonomics cost for anyone who runs `git submodule update
--init --recursive` out of habit, even if they never touch the code that
needs it (see issues.md / docs/architecture.md's discussion of exactly
this tradeoff on the amir_neowise_q8 branch, which does use a submodule
for its own out-of-tree kernel and pays this cost deliberately, as an
explicitly opt-in branch -- master does not carry that tradeoff for
anything, and this vendoring choice keeps it that way).
