Summary: Following pytorch#988 we added TP support for int4_weight_only quantization in torchao that's using TensorCoreTiledLayout Addresses one work item in pytorch#988 Also clarified docs based on pytorch#386 Also restructructured the tests in test/dtypes/test_affine_quantized_tensor_parallel.py to not depend on torchao/utils.py to reduce the jumps people have to do to understand what is tested Test Plan: python test/dtypes/test_affine_quantized_tensor_parallel.py Reviewers: Subscribers: Tasks: Tags:

Summary:
Following #939 we added TP support for int4_weight_only quantization in torchao that's using TensorCoreTiledLayout
Addresses one work item in #988
Also clarified docs based on #386
Also restructructured the tests in test/dtypes/test_affine_quantized_tensor_parallel.py to not depend on torchao/utils.py to reduce the jumps people have to do to understand what is tested
