Gravitational wave science requires high-fidelity numerical simulations of the expected merger events. The Simulating eXtreme Spacetimes (SXS) collaboration has managed the development of two distinct codes for this purpose: (i) the Spectral Einstein Code (SpEC) based on pseudospectral methods, and (ii) an open-source code SpECTRE, an hp-adaptive discontinuous Galerkin scheme that also includes a sub-cell finite volume scheme in regions of strong shock formation that is ideally suited for multi-scale, multi-physics problems. SpECTRE targets problems in multi-messenger astrophysics, including neutron star mergers, core-collapse supernovae, and gamma-ray bursts. It runs at petascale and is designed for future exascale computers. Our weeklong program includes two contemporaneous activities: (i) a focused SpEC and SpECTRE code developers meeting and (ii) a SpECTRE workshop. The code developers' meeting will bring together researchers who are actively developing these codebases. The SpECTRE workshop aims to provide graduate students, postdocs, and faculty with the tools needed to install, run, and contribute to the open-source code SpECTRE. Our SpECTRE workshop will cover topics such as the generalized harmonic formulation of the Einstein field equation, general relativistic hydrodynamics, the discontinuous Galerkin method with finite volume sub-cells, the Cauchy characteristic extraction method, installing, running, and visualizing numerical simulations, and how to get involved with code development.

This symposium brings together mathematicians, computer scientists, chemists and physicist to address a truly multidisciplinary issue of enabling large-scale atomistically-resolved, ab initio materials modeling. Such modeling capabilities are required for understanding and rational design of materials ranging from alloys to solid electrolytes for fuel cells. There is a substantial gap in theory and computing techniques which on one hand would be able to model phenomena intrinsically requiring models with millions of atoms and on the other hand provide accuracy and insight which is today routinely achievable only for unrealistically small model systems . This is a gap between a model and a reality. To bridge it, this symposium makes brains from different research fields pull in one direction. Progress that this symposium will help accelerate will mean better computational support for the development of functional materials, with more of the development moved from time-, manpower-, and $-costly lab experimentation to in-silico design.

Emergent phenomena are the essence of condensed-matter physics and at the same time what makes the behavior of correlated materials appealing for applications. They are, however, hard to understand at a fundamental level. It is the interplay of several competing interactions — none of which can be treated as a mere perturbation, leading to the emergence of effective interactions — that makes their description a grand challenge. Addressing this problem requires mastery of a wide spectrum of theoretical concepts, ranging from materials modeling using first-principles approaches to advanced many-body methods based on dynamical mean-fields, stochastic simulations and renormalization techniques. The concepts of symmetry, topological invariance and the classification of transitions between phases are of crucial importance to bring order to the plethora of observed phenomena.

The goal of this year’s school is to provide students with an overview of the state-of-the-art in the field of emergent phases in strongly correlated systems and the many techniques used to investigate them. The program will start with fundamental models and concepts, introducing the Hubbard and Anderson Hamiltonians and their physics, and providing an overview of field-theoretical aspects of condensed-matter physics. More advanced lectures will introduce symmetries, Berry phases and topological quantum matter. The focus will then turn to emergent phenomena: superconductivity, conventional and non-conventional, Kondo and heavy-fermion behavior, Kosterlitz-Thouless transitions, Mott phases, orbital-ordering, and quantum phase transitions. The topics will be treated both from the view point of simple models and that of real materials, with an outlook on materials design from the theoretical and experimental viewpoint. The theoretical approaches covered will go from density-functional-theory-based methods to dynamical mean-field theory and quantum Monte Carlo. Experimental lectures will cover phenomena under normal and extreme conditions.

MODE (for Machine-learning Optimized Design of Experiments) is a collaboration of physicists and computer scientists who target the use of differentiable programming in design optimization of detectors for particle physics applications, extending from fundamental research at accelerators, in space, and in nuclear physics and neutrino facilities, to industrial applications employing the technology of radiation detection. Our aim to develop modular, customizable, and scalable, fully differentiable pipelines for the end-to-end optimization of articulated objective functions that model in full the true goals of experimental particle physics endeavours, to ensure optimal detector performance, analysis potential, and cost-effectiveness.

The CHEP conference series addresses the computing, networking and software issues for the world’s leading data‐intensive science experiments that currently analyse hundreds of petabytes of data using worldwide computing resources.

The National Centre for Atmospheric Science is a world leading research centre, supported by the Natural Environment Research Council.

The Model for Prediction Across Scales – Atmosphere (MPAS-A) is next-generation numerical atmospheric model that employs state-of-the-art numerics and software engineering, while incorporating physical parameterization schemes from the WRF-ARW model. MPAS-A solves the compressible non-hydrostatic equations, supporting applications from global scales to the explicit simulation of clouds, and it uses horizontally unstructured meshes that permit continuous mesh refinement in both global and regional configurations. Leading scientists from the US National Center for Atmospheric Research (NSF-NCAR) will introduce you to MPAS-A and MPAS-JEDI.
