Sustainable and Reliable Computing with Tools: Analyzing Precision Appetites of CFD Applications with VerifiCarlo
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, processors have been speeding up much faster than memory, what you may know as RAM in your laptop. It started in the 1980s when central…

Reliable and sustainable computations: An application-driven approach
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…
