New supercomputing record set by ANSYS, HLRS and Cray ​- 2017/02/17

New supercomputing record set by ANSYS, HLRS and Cray ​ ANSYS, the High Performance Computing Center (HLRS) of the University of Stuttgart and Cray Inc. have set a new supercomputing world record enabling organizations to create complete virtual prototypes of products faster than ever. ANSYS Fluent has been scaled to 172,032 computer cores on the HLRS supercomputer Hazel Hen, a Cray XC40 system, running at 82 percent efficiency. This is nearly a 5x increase over the record set two years ago when Fluent was scaled to 36,000 cores. By leveraging high performance computing (HPC), companies can rapidly iterate their products.

Scania cooperates with PDC to further improve its vehicles – 2017/02/23

Scania cooperates with PDC to further improve its vehicles Scania, “a very large and well-known Swedish automotive company“ establishes a partnership with PDC Center for High Performance Computing at the KTH Royal Institute of Technology to further improve the efficiency and performance of its vehicles using state of the art simulation and testing techniques. Simulation and testing are critical components of the product development process at Scania. Before the use of high performance computing technologies, developing new vehicle components and designs was a time-consuming and costly process as prototypes of new ideas had to be built and then tested to

CERFACS and CNRS perform first-ever Large Eddy Simulation of combustion instabilities in a rocket engine – 2017/05/09

CERFACS and CNRS perform first-ever Large Eddy Simulation of combustion instabilities in a rocket engine In a collaborative work with CERFACS, Institut de Mécanique des Fluides de Toulouse, Centralesupelec, ONERA, DLR and TU Munchen, researchers have been able to use the CERFACS LES code AVBP to simulate the instabilities which appear in certain rocket engines under extreme conditions. The simulation was performed thanks to a PRACE allocation of 80 M hours. The massively parallel capacities offered by AVBP have allowed the code to run on 65 536 processors in production mode (the code itself scales up to 200 000 cores) on the

A French SME boosts its offshore engineering service portfolio thanks to European HPC initiatives – 2017/05/10

A French SME boosts its offshore engineering service portfolio thanks to European HPC initiatives The French SME, PRINCIPIA, located in southern France, manages to add to its portfolio an innovative service that helps improve the control of the dynamical behaviour of offshore structures while strongly reducing computing time. The La Ciotat-based company, which specializes in applied engineering for the offshore sector (oil and gas and renewable marine energy) and is the main developer of reference software in this field, has successfully adapted one of its simulation codes, DEEPLINES, to run on a high performance computing (HPC) system. DEEPLINES is created

BSC and NVIDIA a step forward to the interactive simulation of humans – 2017/06/19

BSC and NVIDIA a step forward to the interactive simulation of humans ​ Due to the travel restrictions linked to the corona virus, we have successfully organised our first EXCELLERAT virtual All Hands Meeting with more than 40 participants. Instead of hosting it in Stockholm from 5th until 7th May, this was our team’s largest online conference so far. During this All Hands Meeting, the current status of all work packages were presented and our codes’ use cases were discussed. Moreover, we exchanged knowledge and experience on behalf of our working groups, and prepared our upcoming project review. To sum

HPC helps to make combustion plants safe and cost-efficient – 2018/03/02

HPC helps to make combustion plants safe and cost-efficient There’s no getting around High Performance Computing (HPC) for RECOM Services, a Stuttgart-based small and medium-sized enterprise (SME) for computational process optimization and problem analysis in industrial combustion. Their specifically developed 3D-simulationssoftware RECOM-AIOLOS is able to illustrate combustion processes in virtual reality without disturbing the ongoing operation. Naturally, both engineering and HPC know-how is needed in order to succeed. ©RECOM Natural Gas-Combustion Six codes to define success of EXCELLERAT In order to ensure that the processes visualized in virtual reality correspond to the real world, selected operating conditions are both simulated and measured.

EU-Project helps Engineering SME Improve Competitive Position – 2018/05/03

EU-Project helps Engineering SME Improve Competitive Position Current practice in the design of hydro-power plants is to determine empirically the most suitable design in a series of time-consuming experiments. However, SMEs in this sector have to face private and public tenders to sell their turbines in both national and global markets, where the competition is very strong and the development time is very short. The challenge facing Zeco was therefore to improve their design processes to remain competitive.  Their idea was to make extensive use of HPC-based high-fidelity simulations of flow in the turbines by using CFD-based tools. The development

New analysis methods facilitate the evaluation of complex engineering data – 2019/02/12

New analysis methods facilitate the evaluation of complex engineering data A further increase in the performance of supercomputers is expected over the next few years. So-called exascale computers will be able to deliver more precise simulations. This leads to considerably more data. Fraunhofer SCAI develops efficient data analysis methods for this purpose, which provide the engineer with detailed insights into the complex technical contexts. Simulations on supercomputers answer important industrial questions, such as how air flows behave in air conditioning systems, on rotor blades or for entire airplanes. In the coming years, new approaches to hardware design will make computers

Preparing Cloud Physics for Exascale – 2019/06/04

Preparing Cloud Physics for Exascale Cloud model (MONC) is an atmospheric model used throughout the weather and climate community to study clouds and turbulent flows. This is often coupled with the CASIM microphysics model, which provides the capability to investigate interactions at the millimetre scale and study the formation and development of moisture. One of the main targets of these models is the problem of fog, which is very hard to model due to the high resolution required – for context the main UK weather forecast resolves to 1km, whereas the fog problem requires 1metre or less. A major driver here
