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.
Success Story: In situ VR visualisation of Nek5000 simulations with Vistle
Nek5000 cases that use Exascale level performance compute data on very large grids. Writing this data to disk frequently becomes a major run time bottleneck, while handling all the data on disk comes with its own challenges. With increasing data sizes and complexity analysing the usually 3D data with conventional 2D methods becomes even harder. Running large simulations is also costly, therefore errors should better be identified rather sooner than later.
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.
Success Story: Running AVBP Industrial code on Arm architectures
With the diversification of the micro-processor catalogue for High-Performance systems, porting and evaluating software performance on Arm-based architectures has become an imperative step for code developers. For core performance to multi-node scalability, real application benchmarks remain elusive. Given the myriad of Arm flavours available, a comprehensive real case benchmark would give developers and users a first look for the future usage of the European Processor Initiative (EPI) and Arm-based leadership class systems.
In collaboration with Arm Ltd., CERFACS has performed a first benchmark using the AVBP code, a state-of-the-art Navier Stokes solver on unstructured grids for reactive compressible flows written in Fortran and based on MPI for parallelism.

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.
