EXCELLERAT’s Fourth Digital All-Hands Meeting Our project meeting took place from 30 November to 1 December 2021. For the fourth time in a row, it was hosted as a digital event, given the continuing pandemic situation. Representatives from all partners, a total of about 30 participants on each day, presented the EXCELLERAT project tasks’ good progress, some minor challenges they faced in 2021, as well as the requirements for the project’s extension and great final results. The focus of Tuesday’s meeting (first day) was on the communication and dissemination activities undertaken to promote the project and its achievements, business development

How can SMEs benefit from using High Performance Computing (HPC) Cloud? How can SMEs benefit from using High Performance Computing (HPC) Cloud? Growth in Europe is unthinkable without the 23 million small and medium-sized enterprises (SMEs). They represent 99.8 percent of all European companies and form the foundation for innovation, competition and jobs. SMEs provide two thirds of private sector jobs (almost 90 million) and contribute to more than half of the total added value created by businesses in the EU. Nine out of ten SMEs are actually micro enterprises with fewer than 10 employees. They account for nearly 30%
Success Story: Enabling Nek5000 on GPU systems Success story # Highlights: Keywords: GPU NVIDIA AMD OpenACC OpenMP SEM Nek5000 Industry sector: Automotive, Aerospace Key codes used: Nek5000 Fig. 2: Speedup of the OpenACC/CUDA version for a pipe simulation performed on JUWELS Booster at JSC Organisations & Codes Involved: The Swedish e-Science Research Centre (SeRC) is a national e-science initiative, funded by the Swedish government Strategic Research Area Initiative, dedicated to provide e-infrastructure support and to improve important e-science software on future HPC platforms. The largest part of this support is provided by giving researchers access to the national computational experts and
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.
EXCELLERAT’s Third Virtual All-Hands Meeting Our project meeting took place from 8 to 9 June 2021. For the third time in a row, it was hosted as a virtual event, given the continuing pandemic situation. Representatives from all partners, a total of more than 30 participants on both days, presented the EXCELLERAT project tasks’ good progress, some challenges they faced in the first half of 2021 and expect for the rest of this project phase, as well as the needs for a continuous evolution and for mastering the final project months (including its extension by three months). On the first
