GEMM with Microscaling
This example demonstrates a GEMM operation with microscaling, an advanced quantization technique that applies fine-grained scaling to small blocks of data. Microscaling enables more precise quantization than traditional methods by using different scale factors for small groups of elements, leading to better accuracy preservation in quantized neural network inference.
Source Code Organization
gemm_microscaling_xdl.cpp: The main example file. It sets up microscaled matrices with quantized data and scale factors, and instantiates theDeviceGemmMicroscalingoperation.../../include/ck/tensor_operation/gpu/device/device_gemm_microscaling.hpp: The device interface for GEMM with microscaling support.- The underlying kernel implements sophisticated block-wise dequantization integrated into the GEMM computation pipeline.
