White Paper: Empowering Large-Scale Turbulent Flow Simulations With Uncertainty Quantification Techniques
An effective, robust simulation must account for potential sources of uncertainty. Computational fluid dynamics (CFD), in particular, has to deal with many uncertainties from various sources. The real world, after all, forces many kinds of uncertainties upon engineering components – everything from changes in numerical and computational parameters to uncertainty in initial and boundary conditions and geometry. No matter how expensive a flow simulation is, the uncertainties have to be assessed. In CFD, uncertainty is inevitable. But it presents us with a question: how do you know which uncertainties to expect and quantify without using an enormous amount of computing power?
EXCELLERAT Conference: Impressions, Takeaways, and How to Watch
Nearing the end of its 3.5 year run, EXCELLERAT hosted a two-day online conference last week to present the industrial and broader European perspective on the project’s first run. Called “EXCELLERAT: Enabling Exascale potentials for engineering applications,” it showcased the impact, innovations, and tools that resulted from the work of the European Centre of Excellence for Engineering Applications.
White Paper: Enabling High-Performance Collaboration – A Data exchange platform for high-performance computing
As part of the EXCELLERAT project, SSC is developing a secure data exchange and transfer platform to facilitate the use of High-Performance Computing (HPC) in industry and to make data transfer more efficient.
Data management workflow for HPC – SSC Data Management Workflow Portal
Organisations and smaller industry partners today face various problems in dealing with high performance computing (HPC) computations, HPC in general, or even access to HPC resources. Hence, the EXCELLERAT Data Management Service develops best practices and provides support for managing the large amounts of data generated and used in technical HPC applications.
On the technical debt of high-performance scientific software
High-performance scientific software must overcome two specific challenges: scientific validation, and performance on bleeding-edge and short-lived hardware. Success in each requires time, expertise, and cumulative experience over many failed attempts. Thus, engineering software developers are mostly experts in physical modelling or in high-performance computing (HPC) and rarely experts in the management of technical debt.
Key points and take-outs from the FORTRAN webinar organised by EXCELLERAT
The EXCELLERAT Centre of Excellence held a Webinar with Wadud Miah on the topic “Fortran for High Performance Computing” on the 4th of May 2021. Following this event, CERFACS created a COOP blog article with the objective to further share the answers to the questions discussed during the webinar with the HPC ecosystem.
EXCELLERAT’s Fourth All-Hands Meeting
From 30 November to 1 December 2021, our project meeting was once again hosted as a digital event due to the continuing pandemic situation. About 30 partner representatives per day presented the EXCELLERAT project tasks’ good progress, some minor 2021 challenges, and the requirements for the project’s extension and great final results.
EXCELLERAT Exploitation Strategy Seminar with Horizon Results Booster for Vistle, Alya and Uqit
In collaboration with experts from Horizon Results Booster (HRB), EXCELLERAT has completed its first internal Exploitation Strategy Seminar for three selected Key Exploitable Results (KERs): Vistle, Alya and UQit. After an introduction by Dr. Péter Mogyorósi, the HRB expert, partners presented and discussed each KER and its exploitation strategy with HRB experts.
How can SMEs benefit from using High Performance Computing (HPC) Cloud
European growth is unthinkable without its 23 million small and medium-sized enterprises (SMEs). Representing 99.8 percent of European companies, they form the foundation for innovation, competition, and jobs. It’s important to support these SMEs in sustainable development through innovation, processes optimisation, and increased competitiveness: e.g. through the software and data processing support of HPC.
Road and Scouts: a versioning strategy for large Research software.
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.
