[Host10] Upcoming webinar: Accelerating Numerical Software Libraries with Multi-Precision Algorithms

Fri Apr 17 05:59:30 CDT 2020

The next webinar in the HPC Best Practices (http://ideas-productivity.org/events/hpc-best-practices-webinars/) series is:
Accelerating Numerical Software Libraries with Multi-Precision Algorithms
1:00-2:00 ET
Wednesday May 13, 2020
Presenters: Hartwig Antz (Karlsruhe Institute of Technology), and Piotr Luszczek (University of Tennessee)

Description: With the rise of machine learning, more hardware manufacturers are introducing low-precision special function units in processor designs, often achieving up to an order or magnitude higher performance than in the IEEE double precision that is typically used as working precision in scientific computing. At the same time, a rapidly expanding landscape of mixed- and multi-precision methods generate high-quality solutions that leverage the higher compute power of reduced precision. This webinar will introduce the concept of floating point formats and the IEEE standard. We will demonstrate how using an iterative or direct solver in lower precision impacts the solution quality. We will outline several strategies that aim to preserve numerical stability and high solution quality while still computing, at least partially, in lower precision. We will present several multi-precision algorithms that have proven particularly successful and elaborate on their realization and usage. We also
will introduce open source production-quality multi-precision software packages and show their integration and efficiency for scientific applications. The webinar will focus on lessons learned and generally applicable strategies.
Participation is free, but registration is required.
