We are happy to announce that our proposal for a SIAM PP22 Minisymposium was accepted. The SIAM Parallel Processing conference series is unique in its emphasis on the intersection between high performance scientific computing and scalable algorithms, architectures, and software. The conference provides a forum for communication among the applied mathematics, computer science, and computational science and engineering communities. SIAM PP22 takes place in a hybrid format from February 23-26, 2022, in Seattle, WA. The full program can be viewed at:

Our minisymposium, to take place on February 25, 2022, is titled “Advances in Performance Modeling of Parallel Code.” It is organized by Georg Hager (NHR@FAU) and Alexandru Calotoiu (ETH Zurich). Here’s the abstract:

Performance modeling is an indispensable tool for the assessment, analysis, prediction, and optimization of parallel code in scientific computing and computational science. Modeling approaches can take a variety of forms, from purely analytic, first-principle models to curve fitting, machine learning, and AI-based solutions. The goals of modeling are just as diverse: Identification of bottlenecks or scaling problems, extrapolation, architectural exploration, and even the prediction of power dissipation and energy consumption can all be supported be modeling procedures. This minisymposium tries to provide an overview of the current state of the art in performance, or more generally, resource modeling of parallel code. The hardware focus will be very broad, from the node to the massively parallel level, including standard multicore systems, GPUs, and reconfigurable hardware. Contributions will cover fundamental research as well as tools development and case studies. After the minisymposium, the organizers plan to issue an open call for a journal special issue.
