Basic Linear Algebra Subprograms (BLAS) are used everywhere in machine learning and deep learning applications today. OpenBLAS is an optimized BLAS open source library used widely in AI workloads that implement algebraic operations for specific processor types.
This talk covers recent optimization in the OpenBLAS library for the POWER10 processor. As part of this optimization, assembly code for matrix multiplication
kernels in OpenBLAS is converted to C code using new compiler builtins. A sample optimization for matrix multiplication for POWER hardware in OpenBLAS will be used to explain how builtins are used and show the impact of application performance.
