Researchers at the University of Regensburg in Germany are expanding the exploration of the origins of the universe thanks to the new Fujitsu supercomputer, the PRIMEHPC FX700, supported by the new Arm-based processor Fujitsu A64FX. Thus, the university’s QPACE4 project (QCD Parallel Computing Engine 4) can now gain new insights, using the supercomputing technology developed by Fujitsu for the Fugaku supercomputer recently ranked No. 1 on the TOP500 list of world supercomputers.
Its scientists take advantage of the significant increase in computing power for numerical simulations as part of their exploration of quantum chromodynamics (QCD). This work aims to better understand the fundamental particles, including the internal structure of the proton, and ultimately 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, focusing on cancer research and immunology.
The University of Regensburg will employ the supercomputing technology developed by Fujitsu for the Fugaku supercomputer
The installation of QPACE4 makes the University of Regensburg the first user in Europe to use the Fujitsu PRIMEHPC FX700 with A64FX processors (CPUs), the latest in a long series of supercomputing milestones achieved by Fujitsu. These CPUs are compliant with the Armv8.2-A SVE, the latest instruction set architecture for high performance servers and which is particularly energy efficient.
QPACE4 is the fourth supercomputer under SFB / TRR-55, funded by the German Research Foundation (DFG). It uses the same processor as the Fugaku supercomputer , which has been jointly developed by Fujitsu with the world-renowned RIKEN, Center for Computer Science in Kobe, Japan.
In addition to superior performance per watt, the A64FX processor also incorporates Scalable Vector Extensions (SVEs). Developed for applications in high performance computing (HPC), accelerate complex calculations, allowing the same mathematical operation is carried out in parallel on large amounts of data. Likewise, the processor is coupled to an extremely fast main memory (High Bandwidth Memory, or HBM2), which for most applications is as important as pure computing power, providing a very balanced relationship between computing power, width band memory and network, avoiding performance bottlenecks. Another important difference is that the computing power of the Fujitsu system is not based on graphics cards. This makes it much easier to program, especially in the case of mass parallelization, which is essential for applications called “Grand Challenge”
The deployment of the new supercomputer in Regensburg is the latest example of the University’s extremely strong partnership with Fujitsu , based on HPC and on supercomputers in particular. In 2016, together with the University of Wuppertal, he took over the Fujitsu QPACE3 supercomputer – installed at the Jülich Supercomputing Center (JSC) near Cologne.
