‘Enabling mixed-precision with the help of tools: A Nekbone case study’ at PPAM24
—
by
If you’re going to PPAM24 September 8 – 11 in Ostrava, Czechia, make sure to check out the talk by Yanxiang Chen from our partner UMU on their progress implementing and optimizing mixed precision in Nekbone toward its integration in Neko and NekRS. The accompanying paper is also available as a pre-print online: https://arxiv.org/pdf/2405.11065

Energy to Solution Best Practice Guide
Measuring energy to solution isn’t just more complicated than measuring time to solution, it’s also less familiar and less top of mind for most users. Hence, CEEC has published our experience and some best practices to help the EuropeanHPC community learn more about measuring energy to solution across systems and applications.

Summer Round-Up
It’s been a while since our last update, and we’re still in the early days of our work. That said, we’ve been travelling to introduce ourselves and present some of the work we’ll be building on during our 4 project years. Maybe you’ve seen us? This summer we had various presentations both at ISC High-Performance…

VPREC to analyze the precision appetites and numerical abnormalities of several proxy applications
—
by
The third in a series of presentations from Roman Iakymchuk on work using tools to investigate mixed precision possibilities. He and his co-author Pablo de Oliveira Castro introduce an approach to address the issue of sustainable computations with computer arithmetic tools. They use the variable precision backend (VPREC) to identify parts of code that can…

Sustainable and Reliable Computing with Tools: Analyzing Precision Appetites of CFD Applications with VerifiCarlo
—
by
Energy consumption constraints for large-scale computing encourage scientists to revise the architecture design of hardware but also applications, algorithms, as well as the underlying working/ storage precision. I will introduce an approach to address the issue of sustainable, but still reliable, computations from the perspective of computer arithmetic tools. We employ VerifiCarlo and its variable…

What is Mixed Precision?
What is Mixed Precision? Computers have been getting faster for as long as they’ve existed. However, not every computer part has been speeding up at the same rate. For example, […]

Reliable and sustainable computations: An application-driven approach
—
by
In this talk, Roman Iakymchuk presents his work on accuracy and reproducibility assuring strategies for parallel iterative solvers that may not hold due to the non-associativity of floating-point operations. These strategies primarily rely on guarding every bit of result until final rounding, hence they can be costly. The energy consumption constraint for large-scale computing encourages…
