This DistributedReshape aims at supporting all sharding patterns encountered in llama 2. All patterns found are tested in `TestDistributedReshape` in `onnxruntime_test_distributed.py`. This PR implements algorithms to compute the categories below. - All inputs and outputs are replica, so it's computed like a normal Reshape. - Two-axis fusion (if any of the inputs and outputs are sharded). This category convers, e.g., `[batch, seq, hidden] -> [batch x seq, hidden]`. - Two-axis decomposition (if any of the inputs and outputs are sharded). This category convers, e.g., `[batch x seq, hidden] -> [batch, seq, hidden]`. Review guideline: - Ignore the changes in sharding_spec.h and sharding_spec.cc since they come from another PR #18025. - First, read onnxruntime_test_distributed.py to get familiar with the input/output of DistributedReshape. - Second, check the new APIs in reshape.h/reshape.cc to expose CUDA Reshape kernel to DistributedReshape. - For DistributedReshape, check its `ComputeInternal` for the 3 categories mentioned above. |

ONNX Runtime is a cross-platform inference and training machine-learning accelerator.
ONNX Runtime inference can enable faster customer experiences and lower costs, supporting models from deep learning frameworks such as PyTorch and TensorFlow/Keras as well as classical machine learning libraries such as scikit-learn, LightGBM, XGBoost, etc. ONNX Runtime is compatible with different hardware, drivers, and operating systems, and provides optimal performance by leveraging hardware accelerators where applicable alongside graph optimizations and transforms.
