- 7. 7 READ ARTICLE Back in June, the EuroHPC Joint Undertaking – which serves as the EU’s concerted supercomputing play – announced its first exascale system: JUPITER, set to be installed by the Jülich Supercomputing Centre (FZJ) in 2023. But EuroHPC has been preparing for the exascale era for a much longer time: eight months before the JU issued its call for exascale host sites, it announced 13 research projects mostly aimed at readiness for extreme- scale computing. Three of those 13 are the “SEA” projects – DEEP-SEA, IO-SEA and RED-SEA – which, respectively, are aimed at preparing programming environments, data management and storage, and interconnects for the imminent arrival of European exascale computing. SEA CHANGES: HOW EUROHPC IS PREPARING FOR EXASCALE
- 8. 8 LEARN MORE The U.S. Department of Energy’s Oak Ridge National Laboratory celebrated the debut of Frontier, the world’s fastest supercomputer and the dawn of the exascale computing era. ORNL CELEBRATES LAUNCH OF FRONTIER THE WORLD’S FASTEST SUPERCOMPUTER “Research that might once have taken weeks to complete, Frontier will tear through in hours, even seconds. Oak Ridge has positioned the United States to lead the world in solving massive scientific challenges across the board.” David Turk Deputy Secretary of Energy
- 9. 9 READ ARTICLE The National Quantum Office of Singapore, VTT Technical Research Centre of Finland, IQM Quantum Computers, and CSC - IT Center for Science (Finland) agree to explore and promote research and development collaboration in the areas of quantum technologies. Under the Memorandum of Understanding, the parties aim to accelerate the development of quantum technology hardware components, algorithms and applications, and collaborate in the areas of quantum- accelerated high-performance computing and both terrestrial and satellite quantum communications. FINLAND AND SINGAPORE’S NATIONAL QUANTUM OFFICE SIGN MOU
- 10. 10 LEARN MORE Polaris, the newest supercomputer at the U.S. Department of Energy’s (DOE) Argonne National Laboratory, is now open to the research community. The system, which is housed at the Argonne Leadership Computing Facility (ALCF), a DOE Office of Science user facility, provides a platform for researchers to prepare codes and workloads for Argonne’s upcoming Aurora exascale supercomputer. Polaris will also support several projects focused on using artificial intelligence (AI) for science and the integration of large-scale research instruments with high performance computing.

- 11. 11 RESOURCES We present an implementation and scaling analysis of a GPU-accelerated kernel for HemeLB, a high-performance Lattice Boltzmann code for sparse complex geometries. We describe the structure of the GPU implementation and we study the scalability of HemeLB on a GPU cluster under normal operating conditions and with real-world application cases. We investigate the effect of CUDA block size and GPU over- subscription on the single-GPU performance, and we present a strong-scaling analysis of multi-GPU parallel simulations using two different hardware models (P100 and V100) and a variety of large cerebral aneurysm geometries. We find that HemeLB-GPU achieves single-GPU speedups of 50x (P100) and 100x (V100) compared to a single CPU core, with good scalability up to 32 GPUs. We also discuss strategies to improve both the kernel performance as well as the scalability of HemeLB-GPU to a larger number of GPUs. The GPU implementation supports the LBGK collision kernel, boundary conditions for walls and inlets/outlets, and several lattice types (D3Q15, D3Q19, D3Q27), and it integrates seamlessly with the existing infrastructure in HemeLB for graph partitioning and parallelization via MPI. It is expected that the GPU implementation will enable users of the HemeLB code to make better utilization of heterogeneous high-performance computing systems for large-scale lattice Boltzmann simulations.
