ChEESE organises a session called “Towards Exascale Supercomputing in Solid Earth Geoscience and Geohazards” at EGU21, which takes place on 19-30 April 2020. This session is covened by Arnau Folch, Steven J. Gibbons, Marisol Monterrubio-Velasco, Jean-Pierre Vilotte and Sara Aniko Wirp.
More about the session:
The leading-edge computational and data facilities of the forthcoming Exascale era will bring a variety of currently inaccessible Solid Earth computational challenges within reach. Firstly, many Geoscience calculations that are currently unaffordable due to the size of the computational domain, necessary model resolution, or insurmountable data requirements, will become increasingly tractable. Secondly, Exascale supercomputing will facilitate probabilistic framework approaches to ever larger and more complex problems, through larger ensembles of model realizations and incorporating high-end data inversion, model data assimilation, and uncertainty quantification. Finally, Urgent High Performance Computing will become a reality with complex numerical simulations, potentially with large model ensembles, becoming possible in near real-time. Numerous natural hazards which pose a direct threat to human life and critical infrastructure (e.g. earthquakes, volcanic eruptions, wildfire, landslides, and tsunamis) can require rapid and well-informed decision making in the emergency management process. The basis for these decisions is often provided by complex and data-intensive numerical models and we face a challenge of designing and implementing robust and powerful workflows (including computing, data management, sharing and logistics, and post processing) which present stakeholders with relevant and accurate results in a timely manner. This transdisciplinary session seeks contributions related to the preparation of codes for Exascale, geoscience workflows and services, adapting codes for emerging hybrid hardware architectures, e-services demanding Urgent HPC, early warning and forecasts for geohazards, hazard assessment, and high-performance data analytics. Examples include codes and workflows for near real-time seismic simulations, full-waveform seismic inversion, ensemble-based forecasts, faster than real-time tsunami simulation, magneto-hydrodynamics simulations, and physics-based hazard assessment.
This session is organized by the Center of Excellence for Exascale in Solid Earth (ChEESE) with the support of the European Plate Observatory System (EPOS), the EUDAT Collaborative Data Infrastructure (EUDAT CDI) and the Partnership for Advanced Computing in Europe (PRACE). The organisers plan to submit a proposal for an Advances in Geosciences (ADGEO) EGU General Assembly special volume on one or more EGU Divisions.

The Platform for Advanced Scientific Computing (PASC) Conference, co-sponsored by the Association for Computing Machinery (ACM) and the Swiss National Supercomputing Centre (CSCS), will be held from July 5 to 8, 2021 at the University of Geneva (Uni Mail), in Geneva, Switzerland.
The 14th annual Oil and Gas High Performance Computing (OG-HPC) Conference, hosted annually at Rice University by the Ken Kennedy Institute, is the premier meeting place for the energy industry to engage in conversations about challenges and opportunities in high performance computing, computational science and engineering, machine learning, and data science. Attended by more than 500 leaders and experts from the energy industry, academia, national labs, and IT industry, this is a unique opportunity for key stakeholders to engage and network to help advance HPC in the energy industry.
The agenda for the conference includes invited keynote speakers, technical program, virtual networking reception, student poster session, and pre and post-conference workshops. This year’s virtual conference will have an online venue for networking, collaborating, and building partnerships focused on high performance computing, computational science and engineering, machine learning, and data science.
Technical themes for conference sessions are developed based on current challenges and the diversity and strengths of the abstracts received.
This conference has become the key venue for planners and practitioners alike. This is a forum for taking the pulse of industry needs and discussing challenges, opportunities and new development at the interface of the energy industry, the IT industry, and the academic and research community.
Co-organised by HPC centres from Singapore, Japan and Australia, SupercomputingAsia (SCA) 2021 is an annual conference that encompasses an umbrella of notable supercomputing and allied events in Asia. SCA21 will be held as a virtual conference from 2 to 4 March 2021. The key objective of SupercomputingAsia conference is to promote a vibrant and relevant HPC ecosystem in Asia. Delegates will be able to gain access to visionary insights from thought leaders in academia and industry, optimum networking opportunities and the Supercomputing community in Asia.
Scalability of parallel applications depends on a number of characteristics, among which is efficient communication, equal distribution of work or efficient data lay-out. Especially for methods based on domain decomposition, as it is standard for, e.g., molecular dynamics, dissipative particle dynamics or particle-in-cell methods, unequal load is to be expected for cases where particles are not distributed homogeneously, different costs of interaction calculations are present or heterogeneous architectures are invoked, to name a few. For these scenarios the code has to decide how to redistribute the work among processes according to a work sharing protocol or to dynamically adjust computational domains, to balance the workload.
The seminar will provide an overview about motivation, ideas for various methods and implementations on the level of tensor product decomposition, staggered grids, non-homogeneous mesh decomposition and a recently developed phase field approach. An implementation of several methods into the load balancing library ALL, which has been developed in the Centre of Excellence E-CAM, is presented. A use case is shown for the Materials Point Method (MPM), which is an Euler-Lagrange method for materials simulations on the macroscopic level, solving continuous materials equations.
The goals of NAFEMS are to:
- Be the recognised independent authority and trusted source for communicating engineering simulation knowledge, and for sharing best engineering modelling, analysis, and overall simulation practices in developing reliable products and innovative solutions.
- Facilitate unbiased worldwide communication and collaboration between industries, academia, and government organisations for the advancement of best practice in multidisciplinary engineering simulation expertise.
- Develop and deliver training and personal educational opportunities that are aligned with the rapidly-advancing engineering simulation technologies.
- Have a strong impact on product quality, development efficiency and safety
PoP will participate in this event on Tuesday afternoon presenting “Parallel Engineering Codes: Performance Optimisation with the POP Methodology” and visit them on their virtual booth.
On 7 – 11 December 2020, POP experts will give an overview of the VI-HPS programming tools suite, explain the functionality of individual tools, and how to use them effectively, and offer hands-on experience and expert assistance using the tools at the 37th VI-HPS Tuning Workshop at Frankfurt, Germany. The workshop will be held online using the Zoom platform.
