Researchers at the University of Regensburg in Germany are extending their exploration of the origins of the universe boosted by a new Fujitsu supercomputer, the PrimeHPC FX700 underpinned by the new Arm-based Fujitsu A64FX processor.

The universitys QPace4 (QCD Parallel Computing Engine 4) project can now reach new insights, using a supercomputer based on technology developed by Fujitsu for the supercomputer Fugaku, recently ranked number one in the TOP500 list of the worlds supercomputers.

The installation of QPace4 makes the University of Regensburg the first user in Europe to use Fujitsus PrimeHPC FX700 with A64FX processors (CPUs) the latest in a long series of supercomputer first-to-market milestones achieved by Fujitsu.

These CPUs are compliant with Arms Armv8.2-A SVE, the newest instruction set architecture for high-performance servers, and are particularly energy efficient.

Scientists at the University of Regensburg are leveraging the significant increase in compute capability for numerical simulations as part of its exploration of quantum chromodynamics (QCD).

This work aims to understand fundamental particles better, including the inner structure of the proton, and ultimately to determine the state of the universe immediately after the Big Bang.

The supercomputer will also be used by the University of Regensburg in the field of bioinformatics, with a focus on cancer research and immunology.

QPace4 is the fourth supercomputer in the framework of SFB/TRR-55, funded by the German Research Foundation (DFG). It utilises the same processor as the supercomputer Fugaku, which was jointly developed by Fujitsu with the world-renowned Riken Center for Computational Science in Kobe, Japan.

As well as superior performance per watt, the A64FX processor also incorporates Scalable Vector Extensions (SVEs). Developed for applications in high performance computing (HPC), this speeds up complex calculations by allowing the same mathematical operation to be carried out in parallel on large amounts of data.

In addition, the processor is coupled to an extremely fast main memory (high bandwidth memory, or HBM2), which for most applications is just as important as pure computing power, delivering a highly balanced ratio of computing power, memory bandwidth and network bandwidth, and avoiding performance bottlenecks.

A further important difference is that the Fujitsu systems computing power is not based on graphics cards. This makes it easier to program, especially in the case of massive parallelisation, which is essential for so-called grand challenge applications.

The deployment of a new supercomputer in Regensburg is the latest example of the Universitys partnership with Fujitsu, based on HPC and supercomputers in particular. In 2016 it took ownership, together with the University of Wuppertal, of the Fujitsu QPace3 supercomputer, installed at the Jlich Supercomputing Centre (JSC) near Cologne.

Professor Tilo Wettig, PhD, professor of physics at the University of Regensburg, says: Again Fujitsu has provided the University of Regensburg with the ultimate supercomputer to progress our work on fundamental physics and research into vital aspects of human health, such as cancer and immunology.

This partnership has proven highly successful over many years. We applaud Fujitsus commitment to maximizing compute power and minimising energy consumption, we have been particularly impressed with Fujitsus flexibility and responsiveness to us as a customer. The time taken to deliver, install, configure and deploy such advanced technology has been nothing short of outstanding.

Rupert Lehner, head of Central and Eastern Europe: Products Europe at Fujitsu, comments: Fujitsu not only has a distinguished track record developing the worlds fastest supercomputers, we also really understand our HPC customers specific needs around performance, applications and service. Our partnership with the University of Regensburg exemplifies that approach and we are proud to be helping the research team there take another step forward using Fujitsu technology.
