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.

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.

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.

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 HiDALOG’s Urban Air Pollution Pilot. HiDALGO developed the pilot and asked the EXCELLERAT team for support during the pilot’s application improvement phase. 

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.

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 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.

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.
