--- _id: '50221' abstract: - lang: eng text: "Memory Gym presents a suite of 2D partially observable environments, namely\r\nMortar Mayhem, Mystery Path, and Searing Spotlights, designed to benchmark\r\nmemory capabilities in decision-making agents. These environments, originally\r\nwith finite tasks, are expanded into innovative, endless formats, mirroring the\r\nescalating challenges of cumulative memory games such as ``I packed my bag''.\r\nThis progression in task design shifts the focus from merely assessing sample\r\nefficiency to also probing the levels of memory effectiveness in dynamic,\r\nprolonged scenarios. To address the gap in available memory-based Deep\r\nReinforcement Learning baselines, we introduce an implementation that\r\nintegrates Transformer-XL (TrXL) with Proximal Policy Optimization. This\r\napproach utilizes TrXL as a form of episodic memory, employing a sliding window\r\ntechnique. Our comparative study between the Gated Recurrent Unit (GRU) and\r\nTrXL reveals varied performances across different settings. TrXL, on the finite\r\nenvironments, demonstrates superior sample efficiency in Mystery Path and\r\noutperforms in Mortar Mayhem. However, GRU is more efficient on Searing\r\nSpotlights. Most notably, in all endless tasks, GRU makes a remarkable\r\nresurgence, consistently outperforming TrXL by significant margins.

Julia leverages a unified and coordinated single-language and ecosystem paradigm and has a proven track record of achieving high performance without sacrificing user productivity. These aspects make Julia a viable alternative to high-performance computing's (HPC's) existing and increasingly costly many-body workflow composition strategy in which traditional HPC languages (e.g., Fortran, C, C++) are used for simulations, and higher-level languages (e.g., Python, R, MATLAB) are used for data analysis and interactive computing. Julia's rapid growth in language capabilities, package ecosystem, and community make it a promising universal language for HPC. This paper presents the views of a multidisciplinary group of researchers from academia, government, and industry that advocate for an HPC software development paradigm that emphasizes developer productivity, workflow portability, and low barriers for entry. We believe that the Julia programming language, its ecosystem, and its community provide modern and powerful capabilities that enable this group's objectives. Crucially, we believe that Julia can provide a feasible and less costly approach to programming scientific applications and workflows that target HPC facilities. In this work, we examine the current practice and role of Julia as a common, end-to-end programming model to address major challenges in scientific reproducibility, data-driven AI/machine learning, co-design and workflows, scalability and performance portability in heterogeneous computing, network communication, data management, and community education. As a result, the diversification of current investments to fulfill the needs of the upcoming decade is crucial as more supercomputing centers prepare for the exascale era. author: - first_name: Valentin full_name: Churavy, Valentin last_name: Churavy - first_name: William F full_name: Godoy, William F last_name: Godoy - first_name: Carsten full_name: Bauer, Carsten id: '90082' last_name: Bauer - first_name: Hendrik full_name: Ranocha, Hendrik last_name: Ranocha - first_name: Michael full_name: Schlottke-Lakemper, Michael last_name: Schlottke-Lakemper - first_name: Ludovic full_name: Räss, Ludovic last_name: Räss - first_name: Johannes full_name: Blaschke, Johannes last_name: Blaschke - first_name: Mosè full_name: Giordano, Mosè last_name: Giordano - first_name: Erik full_name: Schnetter, Erik last_name: Schnetter - first_name: Samuel full_name: Omlin, Samuel last_name: Omlin - first_name: Jeffrey S full_name: Vetter, Jeffrey S last_name: Vetter - first_name: Alan full_name: Edelman, Alan last_name: Edelman citation: ama: Churavy V, Godoy WF, Bauer C, et al.

Several different approaches to realize solid-state quantum emitters with high performance have been pursued and different concepts for energy tuning have been established. However, the properties of the emitted photons are always defined by the individual quantum emitter and can therefore not be controlled with full flexibility. Here we introduce an all-optical nonlinear method to tailor and control the single photon emission. We demonstrate a laser-controlled down-conversion process from an excited state of a semiconductor quantum three-level system. Based on this concept, we realize energy tuning and polarization control of the single photon emission with a control-laser field. Our results mark an important step towards tailored single photon emission from a photonic quantum system based on quantum optical principles. article_number: '1387' author: - first_name: B. full_name: Jonas, B. last_name: Jonas - first_name: Dirk Florian full_name: Heinze, Dirk Florian id: '10904' last_name: Heinze - first_name: E. full_name: Schöll, E. last_name: Schöll - first_name: P. full_name: Kallert, P. last_name: Kallert - first_name: T. full_name: Langer, T. last_name: Langer - first_name: S. full_name: Krehs, S. last_name: Krehs - first_name: A. full_name: Widhalm, A. last_name: Widhalm - first_name: Klaus full_name: Jöns, Klaus id: '85353' last_name: Jöns - first_name: Dirk full_name: Reuter, Dirk id: '37763' last_name: Reuter - first_name: Stefan full_name: Schumacher, Stefan id: '27271' last_name: Schumacher orcid: 0000-0003-4042-4951 - first_name: Artur full_name: Zrenner, Artur id: '606' last_name: Zrenner orcid: 0000-0002-5190-0944 citation: ama: Jonas B, Heinze DF, Schöll E, et al.

This approach is based on the reduced density-matrix functional theory (RDMFT) formulation of the electronic structure problem. For that purpose, the density-matrix functional of the full system is decomposed into an indirectly coupled sum of density-matrix functionals for all its subsystems using the adaptive cluster approximation to RDMFT. The approximations involved in the decomposition and the adaptive cluster approximation itself can be systematically converged to the exact result. The solutions for the density-matrix functionals of the effective subsystems involves a constrained minimization over many-particle states that are approximated by parametrized trial states on the quantum computer similarly to the variational quantum eigensolver. The independence of the density-matrix functionals of the effective subsystems introduces a new level of parallelization and allows for the computational treatment of much larger molecules on a quantum computer with a given qubit count. In addition, for the proposed algorithm techniques are presented to reduce the qubit count, the number of quantum programs, as well as its depth. The evaluation of a density-matrix functional as the essential part of our approach is demonstrated for Hubbard-like systems on IBM quantum computers based on superconducting transmon qubits. article_type: original author: - first_name: Robert full_name: Schade, Robert id: '75963' last_name: Schade orcid: 0000-0002-6268-539 - first_name: Carsten full_name: Bauer, Carsten id: '90082' last_name: Bauer - first_name: Konstantin full_name: Tamoev, Konstantin id: '50177' last_name: Tamoev - first_name: Lukas full_name: Mazur, Lukas id: '90492' last_name: Mazur orcid: ' 0000-0001-6304-7082' - first_name: Christian full_name: Plessl, Christian id: '16153' last_name: Plessl orcid: 0000-0001-5728-9982 - first_name: Thomas full_name: Kühne, Thomas id: '49079' last_name: Kühne citation: ama: Schade R, Bauer C, Tamoev K, Mazur L, Plessl C, Kühne T.

Their importance to various fields,\r\nincluding materials science, chemical sciences, computational chemistry and\r\ndevice physics, is underscored by the large fraction of available public\r\nsupercomputing resources devoted to these calculations. As we enter the\r\nexascale era, exciting new opportunities to increase simulation numbers, sizes,\r\nand accuracies present themselves. In order to realize these promises, the\r\ncommunity of electronic structure software developers will however first have\r\nto tackle a number of challenges pertaining to the efficient use of new\r\narchitectures that will rely heavily on massive parallelism and hardware\r\naccelerators.

At this\r\nstage, it becomes increasingly important to also account for the effects of\r\nphysically inevitable environments. In particular, we study the transport\r\nproperties of the Hubbard-Holstein Hamiltonian that models a large class of\r\nmaterials characterized by strong electron-phonon coupling, in contact with a\r\ndissipative environment. Even in the one-dimensional and isolated case,\r\nsimulating the quantum dynamics of such a system with high accuracy is very\r\nchallenging due to the infinite dimensionality of the phononic Hilbert spaces.\r\nFor this reason, the effects of dissipation on the conductance properties of\r\nsuch systems have not been investigated systematically so far. We combine the\r\nnon-Markovian hierarchy of pure states method and the Markovian quantum jumps\r\nmethod with the newly introduced projected purified density-matrix\r\nrenormalization group, creating powerful tensor-network methods for dissipative\r\nquantum many-body systems. Investigating their numerical properties, we find a\r\nsignificant speedup up to a factor $\\sim 30$ compared to conventional\r\ntensor-network techniques. We apply these methods to study dissipative\r\nquenches, aiming for an in-depth understanding of the formation, stability, and\r\nquasi-particle properties of bipolarons. Surprisingly, our results show that in\r\nthe metallic phase dissipation localizes the bipolarons, which is reminiscent\r\nof an indirect quantum Zeno effect. However, the bipolaronic binding energy\r\nremains mainly unaffected, even in the presence of strong dissipation,\r\nexhibiting remarkable bipolaron stability. These findings shed light on the\r\nproblem of designing real materials exhibiting phonon-mediated\r\nhigh-$T_\\mathrm{C}$ superconductivity." author: - first_name: Mattia full_name: Moroder, Mattia last_name: Moroder - first_name: Martin full_name: Grundner, Martin last_name: Grundner - first_name: François full_name: Damanet, François last_name: Damanet - first_name: Ulrich full_name: Schollwöck, Ulrich last_name: Schollwöck - first_name: Sam full_name: Mardazad, Sam last_name: Mardazad - first_name: Stuart full_name: Flannigan, Stuart last_name: Flannigan - first_name: Thomas full_name: Köhler, Thomas last_name: Köhler - first_name: Sebastian full_name: Paeckel, Sebastian last_name: Paeckel citation: ama: Moroder M, Grundner M, Damanet F, et al.

Up to thousands of specific cytidines are converted into uridines in plant chloroplasts and mitochondria whereas up to millions of adenosines are converted into inosines in animal nucleo-cytosolic RNAs. It is unknown whether these two different RNA editing machineries are mutually incompatible. RNA-binding pentatricopeptide repeat (PPR) proteins are the key factors of plant organelle cytidine-to-uridine RNA editing. The complete absence of PPR mediated editing of cytosolic RNAs might be due to a yet unknown barrier that prevents its activity in the cytosol. Here, we transferred two plant mitochondrial PPR-type editing factors into human cell lines to explore whether they could operate in the nucleo-cytosolic environment. PPR56 and PPR65 not only faithfully edited their native, co-transcribed targets but also different sets of off-targets in the human background transcriptome. More than 900 of such off-targets with editing efficiencies up to 91%, largely explained by known PPR-RNA binding properties, were identified for PPR56. Engineering two crucial amino acid positions in its PPR array led to predictable shifts in target recognition. We conclude that plant PPR editing factors can operate in the entirely different genetic environment of the human nucleo-cytosol and can be intentionally re-engineered towards new targets." author: - first_name: Elena full_name: Lesch, Elena last_name: Lesch - first_name: Maximilian T full_name: Schilling, Maximilian T last_name: Schilling - first_name: Sarah full_name: Brenner, Sarah last_name: Brenner - first_name: Yingying full_name: Yang, Yingying last_name: Yang - first_name: Oliver J full_name: Gruss, Oliver J last_name: Gruss - first_name: Volker full_name: Knoop, Volker last_name: Knoop - first_name: Mareike full_name: Schallenberg-Rüdinger, Mareike last_name: Schallenberg-Rüdinger citation: ama: Lesch E, Schilling MT, Brenner S, et al.

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.

This active self-propulsion prevents them from equilibrating with their thermal environment (e.g. an aqueous solution), thus keeping them permanently out of equilibrium. Nevertheless, the spatial dynamics of active particles might share certain equilibrium features, in particular in the steady state. We here focus on the time-reversal symmetry of individual spatial trajectories as a distinct equilibrium characteristic. We investigate to what extent the steady-state trajectories of a trapped active particle obey or break this time-reversal symmetry. Within the framework of active Ornstein–Uhlenbeck particles we find that the steady-state trajectories in a harmonic potential fulfill path-wise time-reversal symmetry exactly, while this symmetry is typically broken in anharmonic potentials." article_number: '033216' author: - first_name: Lennart full_name: Dabelow, Lennart last_name: Dabelow - first_name: Stefano full_name: Bo, Stefano last_name: Bo - first_name: Ralf full_name: Eichhorn, Ralf last_name: Eichhorn citation: ama: 'Dabelow L, Bo S, Eichhorn R.

The mechanism of formation of such steady states can be understood on\r\nthe basis of the equations of motion. Analytical expressions for steady states\r\nand their numerical simulations are presented and discussed." author: - first_name: H. full_name: Rose, H. last_name: Rose - first_name: O.

Nowadays, heterogeneous parallel platforms with CPUs, GPUs, and FPGAs enable energy-efficient and computationally demanding simulations. We developed the HighPerMeshes C++-embedded Domain-Specific Language (DSL) for bridging the abstraction gap between the mathematical and algorithmic formulation of mesh-based algorithms for PDE problems on the one hand and an increasing number of heterogeneous platforms with their different parallel programming and runtime models on the other hand. Thus, the HighPerMeshes DSL aims at higher productivity in the code development process for multiple target platforms. We introduce the concepts as well as the basic structure of the HighPerMeshes DSL, and demonstrate its usage with three examples, a Poisson and monodomain problem, respectively, solved by the continuous finite element method, and the discontinuous Galerkin method for Maxwell’s equation. The mapping of the abstract algorithmic description onto parallel hardware, including distributed memory compute clusters, is presented. Finally, the achievable performance and scalability are demonstrated for a typical example problem on a multi-core CPU cluster. author: - first_name: Samer full_name: Alhaddad, Samer id: '42456' last_name: Alhaddad - first_name: Jens full_name: Förstner, Jens id: '158' last_name: Förstner orcid: 0000-0001-7059-9862 - first_name: Stefan full_name: Groth, Stefan last_name: Groth - first_name: Daniel full_name: Grünewald, Daniel last_name: Grünewald - first_name: Yevgen full_name: Grynko, Yevgen id: '26059' last_name: Grynko - first_name: Frank full_name: Hannig, Frank last_name: Hannig - first_name: Tobias full_name: Kenter, Tobias id: '3145' last_name: Kenter - first_name: Franz-Josef full_name: Pfreundt, Franz-Josef last_name: Pfreundt - first_name: Christian full_name: Plessl, Christian id: '16153' last_name: Plessl orcid: 0000-0001-5728-9982 - first_name: Merlind full_name: Schotte, Merlind last_name: Schotte - first_name: Thomas full_name: Steinke, Thomas last_name: Steinke - first_name: Jürgen full_name: Teich, Jürgen last_name: Teich - first_name: Martin full_name: Weiser, Martin last_name: Weiser - first_name: Florian full_name: Wende, Florian last_name: Wende citation: ama: 'Alhaddad S, Förstner J, Groth S, et al.

It then observes a corresponding (random) reward, provided the (random)\r\namount of consumed resources remains below the limit. Otherwise, the\r\nobservation is censored, i.e., no reward is obtained. For this problem setting,\r\nwe introduce a measure of regret, which incorporates the actual amount of\r\nallocated resources of each learning round as well as the optimality of\r\nrealizable rewards. Thus, to minimize regret, the learner needs to set a\r\nresource limit and choose an arm in such a way that the chance to realize a\r\nhigh reward within the predefined resource limit is high, while the resource\r\nlimit itself should be kept as low as possible. We derive the theoretical lower\r\nbound on the cumulative regret and propose a learning algorithm having a regret\r\nupper bound that matches the lower bound. In a simulation study, we show that\r\nour learning algorithm outperforms straightforward extensions of standard\r\nmulti-armed bandit algorithms." author: - first_name: Viktor full_name: Bengs, Viktor last_name: Bengs - first_name: Eyke full_name: Hüllermeier, Eyke last_name: Hüllermeier citation: ama: Bengs V, Hüllermeier E.

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.

The high level synthesis of OpenCL codes can play a fundamental role for FPGAs in HPC, because it allows to implement different designs with lower development effort compared to hand optimized HDL. However, Stratix 10 cards are still hard to fully exploit using the Intel FPGA SDK for OpenCL. The implementation of designs with thousands of concurrent arithmetic operations often suffers from place and route problems that limit the maximum frequency or entirely prevent a successful synthesis. In order to overcome these issues for the implementation of the matrix multiplication, we formulate Cannon's matrix multiplication algorithm with regard to its efficient synthesis within the FPGA logic. We obtain a two-level block algorithm, where the lower level sub-matrices are multiplied using our Cannon's algorithm implementation. Following this design approach with multiple compute units, we are able to get maximum frequencies close to and above 300 MHz with high utilization of DSP and memory blocks. This allows for performance results above 1 TeraFLOPS. author: - first_name: Paolo full_name: Gorlani, Paolo id: '72045' last_name: Gorlani - first_name: Tobias full_name: Kenter, Tobias id: '3145' last_name: Kenter - first_name: Christian full_name: Plessl, Christian id: '16153' last_name: Plessl orcid: 0000-0001-5728-9982 citation: ama: 'Gorlani P, Kenter T, Plessl C.
