The Computational Science of Klaus Hasselmann
We review the work of Klaus Hasselmann, one of three recipients of the Nobel Prize in Physics 2021, from the perspective of computational science and engineering (CSE). In addition to highlighting Hasselmann’s extensive contributions to climate science, we shine a light on his groundbreaking work in ocean surface wave dynamics and prediction, which preceded his career in climate research. Early on, Hasselmann also gained a strong interest in elementary particle physics, which led him to develop, in his spare time, a unified theory of particles and fields, and which we outline here. With this review we hope to entice ...

Responsibly Reckless Matrix Algorithms for HPC Scientific Applications
High-performance computing (HPC) achieved an astonishing three orders of magnitude performance improvement per decade for three decades, thanks to hardware technology scaling resulting in an exponential improvement in the rate of floating point executions, though slowing in the most recent. Captured in the Top500 list, this hardware evolution cascaded through the software stack, triggering changes at all levels, including the redesign of numerical linear algebra libraries. HPC simulations on massively parallel systems are often driven by matrix computations, whose rate of execution depends on their floating point precision...

The Influence and Contribution of Jack Dongarra to Numerical Linear Algebra
This article is dedicated to Jack Dongarra on the occasion of him receiving the 2021 ACM Turing Award and concentrates primarily on his contributions to numerical linear algebra, particularly on the development of algorithms and software to reliably and efficiently solve linear algebra problems. We shall look at software projects, a number of them initiated by Jack, ranging from the BLAS and LINPACK through LAPACK to recent projects, such as SLATE, as well as some of his algorithmic contributions. Quoting from one of Jack’s own recent talks, his tenets have been “accuracy, community, innovation, performance, po...

Formal Modeling and Simulation for SARS-CoV-2 Containment Scenarios in Catalonia
We define interrelated models to simulate the spread of SARS-CoV-2 in Catalonia, which can be used to effectively build simulation applications and analyze the effects of nonpharmaceutical interventions. Due to the constant evolution of this pandemic, and the need to take a multidisciplinary approach, we use a formal specification to represent the model and to validate the model assumptions. We discuss the definition of the model using formal languages, and the Specification and Description Language to improve communication between stakeholders. We show formalization details, discuss implications in the validation process,...
