💫 Moore Threads（摩尔线程）mthreads (Triton 3.6)

  • Based on Triton 3.6, x64
  • Available for S4000/S5000

1. Build and run environment

1.1 Use the image (Triton 3.6, MTT-S5000)

If your network connection is available, you do not need to perform the later step 1.x, because dependencies will be fetched automatically during the build.

# Plan A: docker pull (60.5GB)
IMAGE=harbor.baai.ac.cn/flagtree/flagtree-mthreads3.6-py310-torch2.7.1-musa5.1.0-ubuntu22.04:202605-base

1.2 Manually download the FlagTree dependencies

mkdir -p ~/.flagtree/mthreads; cd ~/.flagtree/mthreads
wget https://baai-cp-web.ks3-cn-beijing.ksyuncs.com/trans/mthreads-llvm22-x64_v0.5.1.tar.gz
tar zxvf mthreads-llvm22-x64_v0.5.1.tar.gz

1.3 Manually download the Triton dependencies

The Triton dependencies are already downloaded and installed in the image. If you do not need to build FlagTree or Triton from source, you do not need to download the Triton dependencies.

cd ${YOUR_CODE_DIR}/FlagTree
# For Triton 3.6 (x64)
wget https://baai-cp-web.ks3-cn-beijing.ksyuncs.com/trans/build-deps-triton_3.6.x-linux-x64.tar.gz
sh python/scripts/unpack_triton_build_deps.sh ./build-deps-triton_3.6.x-linux-x64.tar.gz

After executing the above script, the original ~/.triton directory will be renamed, and a new ~/.triton directory will be created to store the pre-downloaded packages. Note that the script will prompt for manual confirmation during execution.

2. Installation Commands

2.1 Source-free Installation

# Note: First install PyTorch, then execute the following commands
python3 -m pip uninstall -y triton  # Repeat the cmd until fully uninstalled
RES="--index-url=https://resource.flagos.net/repository/flagos-pypi-hosted/simple"
python3.10 -m pip install flagtree===0.5.2rc1+mthreads3.6 $RES

After installing flagtree, you can check it with:

python3 -m pip show flagtree

2.2 Build from Source

cd ${YOUR_CODE_DIR}/FlagTree
git checkout -b triton_v3.6.x origin/triton_v3.6.x
export FLAGTREE_BACKEND=mthreads
MAX_JOBS=32 python3 -m pip install . --no-build-isolation -v

3. Testing and validation

Refer to Tests of mthreads3.2 backend

💫 Moore Threads（摩尔线程）mthreads (Triton 3.2)

  • Based on Triton 3.2, x64
  • Available for S4000/S5000

1. Build and run environment

1.1 Use the image (Triton 3.2, MTT-S5000)

If your network connection is available, you do not need to perform the later step 1.x, because dependencies will be fetched automatically during the build.

💫 Moore Threads（摩尔线程）mthreads (Triton 3.1)

  • Based on Triton 3.1, x64/aarch64

3. Testing and validation

Refer to Tests of mthreads3.1 backend

For triton 3.1 kernels that use tl.dot, setting the environment variable export MUSA_ENABLE_SQMMA=1 can improve performance.
