Session II: Leveraging Mixed Precision and Emerging Low Precision Operators in HPC Applications

With ever-increasing need for computation of scientific applications, major energy constraints, and new application domains such as machine learning, general purpose processor arithmetic is entering a new burst of evolution. Novel hardware and software solutions are explored to leverage emerging low precision operators. Indeed, a better fit in precision usage can provide higher flops, higher energy efficiency, lower communication bandwidth and volume needs. To fully exploit this potential for optimization, all the application design ecosystem needs profound evolution with new numerical, low and mixed precision libraries, and dedicated tools for optimizing and debugging computer arithmetic precision. This presentation will focus on VPREC, our most recent extension of Verificarlo to automatically explore mixed and variable precision in existing applications.
