Summary: Pull Request resolved: facebookresearch/FBGEMM#670 X-link: pytorch#3584 Seq INT4 -> INT4 STBE look up is supported in the diff stack: https://www.internalfb.com/diff/D61305978 . This diff supports: 1. The dequanitzation of INT4 -> INT4 STBE look up onto Cuda for all float types 2. Extends the dequantization of INT4 > INT4 STBE look up onto CPU for BF16 The main gap is to handle the dequant for the case when scale bias for INT4 quantized tensor is in the front. While for CPU, just need to add the dequantization for BF16 based on dtype. This will enable us to reduce the network overhead to remote embedding server as well as D2H data transfer from onto GPU host.
