--- _id: '28099' abstract: - lang: eng text: N-body methods are one of the essential algorithmic building blocks of high-performance and parallel computing. Previous research has shown promising performance for implementing n-body simulations with pairwise force calculations on FPGAs. However, to avoid challenges with accumulation and memory access patterns, the presented designs calculate each pair of forces twice, along with both force sums of the involved particles. Also, they require large problem instances with hundreds of thousands of particles to reach their respective peak performance, limiting the applicability for strong scaling scenarios. This work addresses both issues by presenting a novel FPGA design that uses each calculated force twice and overlaps data transfers and computations in a way that allows to reach peak performance even for small problem instances, outperforming previous single precision results even in double precision, and scaling linearly over multiple interconnected FPGAs. For a comparison across architectures, we provide an equally optimized CPU reference, which for large problems actually achieves higher peak performance per device, however, given the strong scaling advantages of the FPGA design, in parallel setups with few thousand particles per device, the FPGA platform achieves highest performance and power efficiency. article_type: original author: - first_name: Johannes full_name: Menzel, Johannes last_name: Menzel - first_name: Christian full_name: Plessl, Christian id: '16153' last_name: Plessl orcid: 0000-0001-5728-9982 - first_name: Tobias full_name: Kenter, Tobias id: '3145' last_name: Kenter citation: ama: Menzel J, Plessl C, Kenter T.

It is especially aimed at massively parallel and linear-scaling electronic structure methods and state-of-theart ab initio molecular dynamics simulations. Excellent performance for electronic structure calculations is achieved using novel algorithms implemented for modern high-performance computing systems. This review revisits the main capabilities of CP2K to perform efficient and accurate electronic structure simulations. The emphasis is put on density functional theory and multiple post–Hartree–Fock methods using the Gaussian and plane wave approach and its augmented all-electron extension. article_number: '194103' author: - first_name: Thomas full_name: Kühne, Thomas id: '49079' last_name: Kühne - first_name: Marcella full_name: Iannuzzi, Marcella last_name: Iannuzzi - first_name: Mauro Del full_name: Ben, Mauro Del last_name: Ben - first_name: Vladimir V. full_name: Rybkin, Vladimir V. last_name: Rybkin - first_name: Patrick full_name: Seewald, Patrick last_name: Seewald - first_name: Frederick full_name: Stein, Frederick last_name: Stein - first_name: Teodoro full_name: Laino, Teodoro last_name: Laino - first_name: Rustam Z. full_name: Khaliullin, Rustam Z. last_name: Khaliullin - first_name: Ole full_name: Schütt, Ole last_name: Schütt - first_name: Florian full_name: Schiffmann, Florian last_name: Schiffmann - first_name: Dorothea full_name: Golze, Dorothea last_name: Golze - first_name: Jan full_name: Wilhelm, Jan last_name: Wilhelm - first_name: Sergey full_name: Chulkov, Sergey last_name: Chulkov - first_name: Mohammad Hossein Bani-Hashemian full_name: Mohammad Hossein Bani-Hashemian, Mohammad Hossein Bani-Hashemian last_name: Mohammad Hossein Bani-Hashemian - first_name: Valéry full_name: Weber, Valéry last_name: Weber - first_name: Urban full_name: Borstnik, Urban last_name: Borstnik - first_name: Mathieu full_name: Taillefumier, Mathieu last_name: Taillefumier - first_name: Alice Shoshana full_name: Jakobovits, Alice Shoshana last_name: Jakobovits - first_name: Alfio full_name: Lazzaro, Alfio last_name: Lazzaro - first_name: Hans full_name: Pabst, Hans last_name: Pabst - first_name: Tiziano full_name: Müller, Tiziano last_name: Müller - first_name: Robert full_name: Schade, Robert id: '75963' last_name: Schade orcid: 0000-0002-6268-539 - first_name: Manuel full_name: Guidon, Manuel last_name: Guidon - first_name: Samuel full_name: Andermatt, Samuel last_name: Andermatt - first_name: Nico full_name: Holmberg, Nico last_name: Holmberg - first_name: Gregory K. full_name: Schenter, Gregory K. last_name: Schenter - first_name: Anna full_name: Hehn, Anna last_name: Hehn - first_name: Augustin full_name: Bussy, Augustin last_name: Bussy - first_name: Fabian full_name: Belleflamme, Fabian last_name: Belleflamme - first_name: Gloria full_name: Tabacchi, Gloria last_name: Tabacchi - first_name: Andreas full_name: Glöß, Andreas last_name: Glöß - first_name: Michael full_name: Lass, Michael id: '24135' last_name: Lass orcid: 0000-0002-5708-7632 - first_name: Iain full_name: Bethune, Iain last_name: Bethune - first_name: Christopher J. full_name: Mundy, Christopher J. last_name: Mundy - first_name: Christian full_name: Plessl, Christian id: '16153' last_name: Plessl orcid: 0000-0001-5728-9982 - first_name: Matt full_name: Watkins, Matt last_name: Watkins - first_name: Joost full_name: VandeVondele, Joost last_name: VandeVondele - first_name: Matthias full_name: Krack, Matthias last_name: Krack - first_name: Jürg full_name: Hutter, Jürg last_name: Hutter citation: ama: 'Kühne T, Iannuzzi M, Ben MD, et al.
