### Description Add stable diffusion CUDA kernel optimizations. The following are included: (1) GroupNorm operator. This kernel is from TensorRT 8.5. (2) BiasSplitGelu operator. This kernel is modified from SplitGelu of TensorRT 8.5. We added bias to the SplitGelu. (3) NhwcConv operator. This adds support of NHWC format (ONNX Conv operator uses NCHW format). (3) Update MultiHeadAttention (packed kv and no bias) for cross attention. This could avoid transpose of kv for TRT fused cross attention kernel. (4) Optimization and benchmark script Not included: (1) Script to convert Conv to NhwcConv in onnx graph. (2) Update symbolic shape inference for NhwcConv. (3) Add SeqLen2Spatial operator (4) Documents Limitations: GroupNorm, BiasSplitGelu and NhwcConv kernels are implemented based on stable diffusion usage. They might not be applicable to any input size or dimensions. For example, BiasSplitGelu requires hidden size to be 2560 | 5120 | 10240, and NhwcConv assumes 4D input/weight. There is minor increasement of binary size. For SM=75 only, python package wheel size adds (33757K - 33640K) = 117 KB. It is possible to move NHWC from template parameter to constructor to reduce binary size (with slight cost of performance). Note: for RTX 4090/4080/4070 Ti, need build with CUDA 11.8 and latest cuDNN to get best performance. |
