FocusCoE at EuroHPC Summit Week 2022
With the support of the FocusCoE project, almost all European HPC Centres of Excellence (CoEs) participated once again in the EuroHPC Summit Week (EHPCSW) this year in Paris, France: the first EHPCSW in person since 2019’s event in Poland. Hosted by the French HPC agency Grand équipement national de calcul intensif (GENCI), the conference was organised by Partnership for Advanced Computing in Europe (PRACE), the European Technology Platform for High-Performance Computing (ETP4HPC), The EuroHPC Joint Undertaking (EuroHPC JU), and the European Commission (EC).As usual, this year’s event gathered the main European HPC stakeholders from technology suppliers and HPC infrastructures to scientific and industrial HPC users in Europe.
At the workshop on the European HPC ecosystem on Tuesday 22 March at 14:45, where the diversity of the ecosystem was presented around the Infrastructure, Applications, and Technology pillars, project coordinator Dr. Guy Lonsdale from Scapos talked about FocusCoE and the CoEs’ common goal.
Later that day from 16:30 until 18:00h, the FocusCoE project hosted a session titled “European HPC CoEs: perspectives for a healthy HPC application eco-system and Exascale” involving most of the EU CoEs. The session discussed the key role of CoEs in the EuroHPC application pillar, focussing on their impact for building a vibrant, healthy HPC application eco-system and on perspectives for Exascale applications. As described by Dr. Andreas Wierse on behalf of EXCELLERAT, “The development is continuous. To prepare companies to make good use of this technology, it’s important to start early. Our task is to ensure continuity from using small systems up to the Exascale, regardless of whether the user comes from a big company or from an SME”.
Keen interest in the agenda was also demonstrated by attendees from HPC related academia and industry filling the hall to standing room only. In light of the call for new EU HPC Centres of Excellence and the increasing return to in-person events like EHPCSW, the high interest in preparing the EU for Exascale has a bright future.
FocusCoE Hosts Intel OneAPI Workshop for the EU HPC CoEs
On March 2, 2022 FocusCoE hosted Intel for a workshop introducing the oneAPI development environment. In all, over 40 researchers representing the EU HPC Centres of Excellence (CoEs)were able to attend the single day workshop to gain an overview of OneAPI. The 8 presenters from Intel gave presentations through the day covering the OneAPI vision, design, toolkits, a use case with GROMACS (which is already used by some of the EU HPC CoEs), and specific tools for migration and debugging.
Launched in 2019, the Intel OneAPI cross-industry, open, standards-based unified programming model is being designed to deliver a common developer experience across accelerator architectures. With the time saved designing for specific accelerators, OneAPI is intended to enable faster application performance, more productivity, and greater innovation. As summarized on Intel’s OneAPI website, “Apply your skills to the next innovation, and not to rewriting software for the next hardware platform.” Given the work that EU HPC CoEs are currently doing to optimise codes for Exascale HPC systems, any tools that make this process faster and more efficient can only boost CoEs capacity for innovation and preparedness for future heterogeneous systems.
The OneAPI industry initiative is also encouraging collaboration on the oneAPI specification and compatible oneAPI implementations. To that end, Intel is investing time and expertise into events like this workshop to give researchers the knowledge they need not only to use but help improve OneAPI. The presenters then also make themselves available after the workshop to answer questions from attendees on an ongoing basis. Throughout our event, participants were continuously able to ask questions and get real-time answers as well as offers for further support from software architects, technical consulting engineers, and the researcher who presented a use case. Lastly, the full video and slides from presentations are available below for any CoEs who were unable to attend or would like a second look at the detailed presentations.
SIMAI 2021
The 2020 edition of the bi-annual congress of the Italian Society of Applied and Industrial Mathematics (SIMAI) has been held in Parma, hosted by the University of Parma, from August 30 to September 3, 2021, in a hybrid format (physical and online). The conference aimed to bring together researchers and professionals from academia and industry that are active in the study of mathematical and numerical models and their application to industry and general real-life problems, stimulate interdisciplinary research in applied mathematics, and foster interactions between the scientific community and industry. Six plenary lectures have been covering a wide range of topics. In this edition, a posters session was also organized to broaden the opportunity to disseminate the results of interesting research. A large part of the conference was dedicated to minisymposia, autonomously organized around specific topics by their respective promoters. Furthermore, an Industrial Session gathering together both academic and industrial researchers was organized, particularly with more than 70 industry representatives focusing on mathematical problems encountered in R&D areas.
Within the SIMAI conference, the minisymposium on HPC, European High-Performance Scientific Computing: Opportunities and Challenges for Applied Mathematics” was organized by ENEA within the framework of project FocusCoE, and a contribution to the aforementioned Industrial Session was given through a talk on results on Hydropower production modelling obtained by project EoCoE. In the minisymposium agenda of 3th of September (9:30-12:00), five presentations (20 min + 5 min Q) have been made from CoEs representatives: Ignatio Pagonabarraga (CoE: E-CAM), Alfredo Buttari (CoE: EoCoE), Francesco Buonocore (CoE: EoCoE), Pasqua D’Ambra (CoEs: EoCoE. EUROHPC project:TEXTAROSSA), Tomaso Esposti Ongaro (CoE: ChEESE). The number of sustained participants has been ca. 25.
The FocusCoE contribution within the industrial session of September 1 (17:50-18:15) has been made through a talk of prof. Bruno Majone (CoEs: EoCoE) presented by Andrea Galletti (CoEs: EoCoE) titled “Detailed hydropower production modelling over large-scale domains: the HYPERstreamHS framework”.

Workflow
The workflow of this pilot is shown in Figure 1.
To use the SeisSol code to run fully non-linear dynamic rupture simulations, accounting for various fault geometries, 3D velocity structures, off-fault plasticity, and model parameters uncertainties, to build a fully physics-based dynamic rupture database of mechanically plausible scenarios.
Then the linked post-processing python codes are used to extract ground shakings (PGD, PGV, PGA and SA in different periods) from the surface output of SeisSol simulations to build a ground shaking database.
SHERIFS uses a logic tree method, with the input of the fault to fault ruptures from dynamic rupture database, converting the slip rate to the annual seismic rate given the geometry of the fault system.
With the rupture probability estimation from SHERIFS, and ground shakings from the SeisSol simulations, we can generate the hazard curves for selected site locations and hazard maps for the study region.
In addition, the OpenQuake can use the physics-based ground motion models/prediction equations, established with the ground shaking database from fully dynamic rupture simulations. And the Cybershake, which is based on the kinematic simulations, to perform the PSHA and complement the fully physics-based PSHA.

Faster Than Real-Time Tsunami Simulations
A Use Case by
Short description
Results & Achievements
Objectives
Technologies
Workflow
The Faster-Than-Real-Time (FTRT) prototype for extremely fast and robust tsunami simulations is based upon GPU/multi-GPU (NVIDIA) architectures and is able to use earthquake information from different locations and with heterogeneous content (full Okada parameter set, hypocenter and magnitude plus Wells and Coppersmith (1994)). Using these inhomogeneous inputs, and according to the FTRT workflow (see Fig. 1), tsunami computations are launched for a single scenario or a set of related scenarios for the same event. Basically, the automated retrieval of earthquake information is sent to the system and on-the-fly simulations are automatically launched. Therefore, several scenarios are computed at the same time. As updated information about the source is provided, new simulations should be launched. As output, several options are available tailored to the end-user needs, selecting among: sea surface height and its maximum, simulated isochrones and arrival times to the coastal areas, estimated tsunami coastal wave height, times series at Points of Interest (POIs) and oceanographic sensors.
A first successful implementation has been done for the Emergency Response Coordination Centre (ERCC), a service provided by the ARISTOTLE-ENHSP Project. The system implemented for ARISTOTLE follows the general workflow presented in Figure 1. Currently, in this system, a single source is used to assess the hazard and the computational grids are predefined. The computed wall-clock time is provided for each experiment and the outputs of the simulation are maximum water height and arrival times on the whole domain, and water height time-series on a set of selected POIs, predefined for each domain.
A library of Python codes are used to generate the input data required to run HySEA codes and to extract the topo-bathymetric data and construct the grids used by HySEA codes.
Software involved
Tsunami-HySEA has been successfully tested with the following tools and versions:
Compilers: GNU C++ compiler 7.3.0 or 8.4.0, OpenMPI 4.0.1, Spectrum MPI 10.3.1, CUDA 10.1 or 10.2
Management tools: CMake 3.9.6 or 3.11.4
External/third party libraries: NetCDF 4.6.1 or 4.7.3, PnetCDF 1.11.2 or 1.12.0
