runmetal: call Apple Metal Framework from Python (or YAML-recipe)

• numpy array -> GPU buffer -> compute -> copy result into numpy array

requirements

• macOS
• Xcode (or CommandLineTools)
  • Metal Framework
• Python 3.x

install

(python)

• brew install pyenv
• pyenv install 3.7.1

(venv)

• python -m venv .
• ./bin/pip install -r requirements.txt
• ./bin/python setup.py install
• ./bin/runmetal run example/xxx.yaml

examples(YAML)

• pi
  • calculate π by monte carlo
    • numpy.random.random()
    • -> copy numpy to GPU buffer
    • -> compute sqrt(xx+yy) < 1.0
    • -> copy GPU buffer to numpy bool8 array
    • numpy.sum(result == True)/len(result)*4
  • runmetal run example/pi.yaml
• rand
  • random number generator (LCG)
