TITLE:    Mixed-precision algorithms: from ML to HPC


ABSTRACT:

IEEE 754 standard for floating-point precisions has served the 
scientific computing community for decades. The advent of deep learning 
marked the race to the bottom for the forever smaller bit 
representations that could still be successfully used in training of 
neural networks of increasing size and complexity. Yet shorter bit 
representations are applied for inference tasks that, unlike training, 
come at the speed of internet search queries. This first expanded and 
subsequently fractured the landscape of floating-point representations, 
reinvigorated the hardware startup scene, and applied pressure on the 
community to develop new mixed precision algorithms and their analysis 
methods. In this talk, I will focus on my contributions to the 
algorithmic side of this burgeoning new field. I will cover a range of 
numerical methods, their convergence properties, and performance 
considerations when applied to HPC benchmarking.
