EXCELLERAT’s First Joint Technical Workshop with ChEESE and HiDALGO Centres of Excellence

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

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

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

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

High-performance computing challenge: How can engineers effectively leverage HPC technology?

High-performance computing challenge: How can engineers effectively leverage HPC technology? When developing or improving products, engineers face the challenge of analysing complex simulations to test their designs. High-performance computing (HPC) is used to solve major problems in engineering by performing demanding operations such as simulations relatively quickly. Also, by processing more precise operations, HPC can avoid the errors that might be introduced by humans. Engineers use HPC mainly for performing simulations: these digital models, comprising huge amounts of numbers and algorithms, can determine a product’s viability. When performing simulations, the experts can track the behaviour of the product by including

EXCELLERAT collaborates with the HiDALGO Centre of Excellence

EXCELLERAT collaborates with the HiDALGO Centre of Excellence The two Centres of Excellence (CoEs) HiDALGO – HPC and Big Data Technologies for Global Systems – and EXCELLERAT are successfully collaborating, for instance in the improvement of HiDALOGO’s Urban Air Pollution Pilot. HiDALGO developed the pilot and asked the EXCELLERAT team for support during the pilot’s application improvement phase. Together they pushed forward the pilot case, as they improved mesh quality, speed-up, and parallel efficiency of the Urban Air Pollution Pilot. This success was efficiently achieved within a few months thanks to the excellent exchange of knowledge and cooperation. Future collaboration

Nek5000 in EXCELLERAT: towards Exascale

Nek5000 in EXCELLERAT: towards Exascale One of EXCELLERAT’s tasks is improving Nek5000’s Exascale readiness, particularly with respect to accelerators. As a starting point, we used an OpenACC version of the proxy-app Nekbone and focused on further optimising the small matrix-matrix kernels which constitutes most of the work in the full Nek5000. By tuning the OpenACC directives, the performance of these kernels could be improved with almost a factor of two, however this was still far from the measured roofline of these kernels. This led to the development of a hybrid OpenACC + CUDA version of Nekbone, where the main part

New EXCELLERAT Service Portal is launched

New EXCELLERAT Service Portal is launched We are pleased to announce the launch of EXCELLERAT’s redesigned Service Portal. By presenting a wide variety of resources in an easily-accessible format, the Portal will play an essential role in EXCELLERAT’s mission to create a Centre of Excellence in Engineering. We have adopted a user-centric approach, and the Portal therefore offers separate dashboards tailored towards engineers, software developers, and the general engineering community. Each dashboard quickly directs users to relevant content, and delivers tailored information accordingly. Each page provides a quick route to any related content and offers an easy way to request

Dynamic Load balancing for Airplane simulations on Heterogeneous pre-Exascale architectures

Dynamic Load balancing for Airplane simulations on Heterogeneous pre-Exascale architectures We can affirm with quite a certainty that future Exascale systems will be heterogeneous, including accelerators such as GPUs. We can also expect higher variability on the performance of the various computing devices engaged in a simulation; due to the explosion of the parallelism, or other technical aspects such as the hardware-enforced mechanisms to preserve the thermal design limits. In this context, dynamic load balancing (DLB) becomes a must for the parallel efficiency of any simulation code. In the first year of the EXCELLERAT project, Alya has been provisioned with

EPCC develops new modelling techniques for the chemical and oil and gas industry ​

EPCC develops new modelling techniques for the chemical and oil and gas industry Global equipment manufacturers in the chemical and oil and gas industry, such as Sulzer Chemtech, often rely on commercial Computational Fluid Dynamics (CFD) software tools for the design of their equipment. These commercial codes are currently unable to handle complex twophase flows which exhibit challenging interfaces between gas and liquids such as travelling waves. The formation of interfacial waves, their frequency and amplitude are particularly difficult to model in industrial environments. Dr Prashant Valluri of the University of Edinburgh and his team accelerate the impact of world
