The largest part of this support is provided by giving researchers access to the national computational experts and
Versioning of large research software applications for industry can be sloppy because audiences have different needs. End-users require a clear official version, while research asks for many exploratory versions.
Born in the 1990s, AVBP is combustion software used and developed today by dozens of industrial users and researchers simultaneously. This post will consider whether it is suitable for a semantic versioning strategy.
EXCELLERAT’s Third Virtual All-Hands Meeting Our project meeting took place from 8 to 9 June 2021. For the third time in a row, it was hosted as a virtual event, given the continuing pandemic situation. Representatives from all partners, a total of more than 30 participants on both days, presented the EXCELLERAT project tasks’ good progress, some challenges they faced in the first half of 2021 and expect for the rest of this project phase, as well as the needs for a continuous evolution and for mastering the final project months (including its extension by three months). On the first
EXCELLERAT Training Workshop: Using Machine Learning To Analyse Engineering Data EXCELLERAT’s latest workshop dealt with data analysis for engineering data, particularly simulation data. Partners from Fraunhofer SCAI conducted this one-day online training course with sessions dedicated to the topics of Clustering, Dimensionality Reduction, Pre-processing of Simulation Data, and two hands-on tutorials with exemplary use-cases from car crash analysis and aeroacoustics. The eight workshop participants were partners and guests from HLRS, KTH, SSC-Services, and University of Trier, who actively contributed to the workshop by eagerly asking questions, initiating important discussions, and experimenting with the introduced data analysis tools in the hands-on
Monitoring High-Performance Computing at scale -introduction and worked example Antoine Dauptain and Elsa Gullaud Foreword Managing massive numbers of HPC engineering simulations Takeaway A worked example of a feedback process Acknowledgements Foreword (Photo Kevin Ku ). There is still a long way to go to before using Tier-O High Performance Computers for engineering design every day. Moving from a handful of demonstration runs to the desired mass production will require special pair of glasses to get insights on how end-users actually used each software on each machine.

The use of in-situ analysis tools by EXCELLERAT Paraview-Catalyst is widely used to perform in-situ visualisation, for example the OpenFOAM and Code-Saturne HPC codes have successfully used this software. In order to use Catalyst, a given code should be prepared. First, an appropriate version of Paraview-Catalyst must be available on the computer system on which the code will be executed. Then the code must be instrumented to transfer its data towards Catalyst. Finally, in most cases, a Python script automatically produced by Paraview must be prepared. This script contains the instructions which will be executed during the run time of
EXCELLERAT’s First Joint Technical Workshop with ChEESE and HiDALGO Centres of Excellence In collaboration with ChEESE and HiDALGO, EXCELLERAT has completed its first joint technical workshop. ChEESE is active in the domain of Solid Earth, targeting the preparation of 10 Community flagship European codes for the upcoming pre-Exascale and Exascale supercomputers. HiDALGO is developing novel methods, algorithms and software to accurately model and simulate the complex processes that arise in connection with major global challenges. The event included a session on each of these topics: Load Balancing, In situ & remote visualisation, Co-design, and GPU Porting. Partners and guests from
Gauging High Performance Computing needs for industrial applications: a worked example Foreword 2020: a tipping point for Computer-aided-design and High performance Computing. Existing monitoring tools on an HPC cluster What is missing for the engineer? for the software developer? Retrieving the missing data What did we learn on this batch of simulations? Conclusion Foreword High performance Computing (HPC) has uses in a wide variety of fields, ranging from fundamental research to industrial design, as measured e.g. by the Technology Readiness Level. It involves actors in both scientific and the engineering communities. This document focuses on the latter, i.e. uses of HPC in industrial applications. The hardships of
EXCELLERAT goes digital: 36th International CAE Conference and Exhibition In partnership with FocusCoE and MaX, EXCELLERAT took part in the CAE2020 International Conference and Exhibition digital event. EXCELLERAT and MaX shared a virtual booth “HPC-COES: MAX & EXCELLERAT” in the Exhibition area. On this booth, visitors could read the prepared flyers, videos, websites, and EXCELLERAT’s social media channels. This digital booth also allowed visitors to interact in a one-to-one video/chat, and to share their contact details or request a meeting. In addition to this digital booth, EXCELLERAT also had a talk in a collateral event: High Performance Computing, a key
EXCELLERAT’s Second Virtual All-Hands Meeting Our second virtual project meeting took place from 9 to 11 December 2020. Representatives from all partners, a total of more than 30 participants on each of the three days, presented the EXCELLERAT project tasks’ progress and challenges they faced throughout this year, as well as the need for a continuous evolution and mastering this final project year. On the first day, the focus was on the general management, communication and dissemination activities on behalf of EXCELLERAT, the services and respectively the updates on the Service Portal, as well as the market context and sustainability
