FBGEMM (Facebook GEneral Matrix Multiplication) is a low-precision, high
performance matrix-matrix multiplications and convolution library for
server-side inference.

The library provides efficient low-precision general matrix multiplication for
small batch sizes and support for accuracy-loss minimizing techniques such as
row-wise quantization and outlier-aware quantization. FBGEMM also exploits
fusion opportunities in order to overcome the unique challenges of matrix
multiplication at lower precision with bandwidth-bound operations.}
