triton-utlx 3.8.0

uTLX: Triton Language Extensions distributed as a Plugin (Triton 3.8)

uTLX — Triton Language Extensions (Plugin), Triton 3.8 build

triton-utlx ships a Triton plugin (libutlx.so) plus the utlx Python DSL exposing the TLX dialect (async loads, warp-group MMA, shared/tensor-memory buffers, etc.), built from triton-lang/triton-ext (extensions/utlx) for Triton 3.8 (the create_utlx_* binding).

Compatibility

Self-contained plugin: libutlx.so depends only on libtriton.so (MLIR symbols resolve from libtriton at load). It works with a Triton 3.8 built from source with a static LLVM and TRITON_EXT_ENABLED=ON (the same model as the 3.7 build):

git clone https://github.com/triton-lang/triton && cd triton && git checkout <3.8 commit>
pip install -r python/requirements.txt
TRITON_EXT_ENABLED=ON pip install -e . --no-build-isolation
pip install triton-utlx
export TRITON_PLUGIN_PATHS=$(python -c 'import utlx_plugin,os;print(os.path.join(os.path.dirname(utlx_plugin.__file__),"libutlx.so"))')

It does not work with a stock statically-linked PyPI triton (built without TRITON_EXT_ENABLED, so it does not export the MLIR symbols the plugin resolves).
