TuringAs

An open source SASS assembler for NVIDIA Volta, Turing, and Ampere GPUs.

Requirements:

Python >= 3.6

Supported hardware:

All NVIDIA Volta (SM70), Turing (SM75), and Ampere (SM80) GPUs.

Other features:

Include files.
Inline python code.

Install the library

python setup.py install

Use the library

python -m turingas.main -i <input.sass> -o <output.cubin> -arch <arch>

# E.g.
python -m turingas.main -i input.sass -o output.cubin -arch 75 # 75 for Turing
                                                               # or 70 (Volta), 80 (Ampere)
