EXCELLERAT Partners at SC23: Nominations, Collaborations, and Cutting-Edge HPC
From November 12 to 17, 2023, the high-performance computing (HPC) world converged at the International Conference for High-Performance Computing, Networking, Storage, and Analysis – SC23 and EXCELLERAT was no exception. With a record over 14,000 attendees and 438 exhibitors, SC23 lived up to its reputation as the premier event for scientists, engineers, researchers, educators, programmers, and developers in the HPC community.
While EXCELLERAT didn’t have a physical booth of its own, its activities were well-represented by project partners: BSC, HLRS, and SiPearl were exhibitors, and KTH was involved in the technical programme.
EXCELLERAT CoE presented at the Day of the Slovenian Supercomputer Network
On Thursday, November 16, 2023, the “Day of the Slovenian Supercomputer Network” was organized by the National Competence Center SLING in Ljubljana, Slovenia. One of the biggest HPC events in Slovenia gathered visitors from the entire HPC value chain.
The varied program included presentations on the activities of the National Competence Center (NCC) and Centers of Excellence (CoEs). Furthermore, examples of the effective use of powerful supercomputers in industry and academia were presented by research institutions and companies, and the possibilities of accessing HPC infrastructure were explained.
EXCELLERAT P2 at SOR23
EXCELLERAT P2 was successfully represented at the 17th International Symposium on Operations Research in Slovenia – SOR’23, held in Bled, Slovenia, September 20-22, 2023.

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.
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.
Press release: EXCELLERAT CoE supports COVID-19-related research
A group of researchers from EXCELLERAT’s consortium partner SSC-Services GmbH, an IT service provider in Böblingen, Germany and the High-Performance Computing Center Stuttgart (HLRS) is supporting the German Federal Institute for Population Research (Bundesinstitut für Bevölkerungsforschung, BiB). SSC has developed an intelligent data transfer platform, which enables the BiB to upload data, start simulations and download results. The platform supports the work of BiB researchers in predicting the demand for intensive care units during the COVID-19 pandemic.
