An aspect of particular interest is the active\r\ncontrol of such patterns. In nonlinear optical systems this can be used for\r\nall-optical switching with transistor-like performance, for example realized\r\nwith polaritons in a planar quantum-well semiconductor microcavity. Here we\r\nfocus on a specific configuration which takes advantage of the intricate\r\npolarization dependencies in the interacting optically driven polariton system.\r\nBesides detailed numerical simulations of the coupled light-field exciton\r\ndynamics, in the present paper we focus on the derivation of a simplified\r\npopulation competition model giving detailed insight into the underlying\r\nmechanisms from a nonlinear dynamical systems perspective. We show that such a\r\nmodel takes the form of a generalized Lotka-Volterra system for two competing\r\npopulations explicitly including a source term that enables external control.\r\nWe present a comprehensive analysis both of the existence and stability of\r\nstationary states in the parameter space spanned by spatial anisotropy and\r\nexternal control strength. We also construct phase boundaries in non-trivial\r\nregions and characterize emerging bifurcations. The population competition\r\nmodel reproduces all key features of the switching observed in full numerical\r\nsimulations of the rather complex semiconductor system and at the same time is\r\nsimple enough for a fully analytical understanding of the system dynamics.","lang":"eng"}],"status":"public"},{"type":"preprint","status":"public","abstract":[{"lang":"eng","text":"<jats:p>&lt;div&gt;\r\n\t\t\t&lt;div&gt;\r\n\t\t\t\t&lt;div&gt;\r\n\t\t\t\t\t&lt;p&gt;Molecular doping in conjugated polymers is a crucial process for their application in organic\r\nphotovoltaics and optoelectronics. In the present work we theoretically investigate p-type molecu-\r\nlar doping in a series of (poly[2,6-(4,4-bis(2-ethylhexyl)-4H-cyclopenta[2,1-b;3,4-b”]dithiophene)-alt-\r\n4,7-(2,1,3-benzothiadiazole)] (PCPDT-BT) conjugated oligomers with different lengths and three\r\nwidely-used dopants with different electron affinities, namely F4TCNQ, F6TCNNQ, and CN6-CP.\r\nWe study in detail the molecular geometry of possible oligomer-dopant complexes and its influence\r\non the doping mechanisms and electronic system properties. We find that the mechanisms of dop-\r\ning and charge transfer observed sensitively depend on the specific geometry of the oligomer-dopant\r\ncomplexes. For a given complex different geometries may exist, some of which show transfer of\r\nan entire electron from the oligomer chain onto the dopant molecule resulting in an integer-charge\r\ntransfer complex, leaving the system in a ground state with broken spin symmetry. In other ge-\r\nometries merely hybridization of oligomer and dopant frontier orbitals occurs with partial charge\r\ntransfer but spin-symmetric ground state.

One of the routines in the critical path of MD simulations is the three-dimensional Fast Fourier Transformation (FFT3d). The potential in accelerating FFT3d using hardware is usually bound by bandwidth and memory. Therefore, designing a high throughput solution for an FPGA that overcomes this problem is challenging.\r\nIn this thesis, the feasibility of offloading FFT3d computations to FPGA implemented using OpenCL is investigated. In order to mask the latency in memory access, an FFT3d that overlaps computation with communication is designed. The implementa- tion of this design is synthesized for the Arria 10 GX 1150 FPGA and evaluated with the FFTW benchmark. Analysis shows a better performance using FPGA over CPU for larger FFT sizes, with the 643 FFT showing a 70% improvement in runtime using FPGAs.\r\nThis FFT3d design is integrated with CP2K to explore the potential in accelerating molecular dynamic simulations. Evaluation of CP2K simulations using FPGA shows a 41% improvement in runtime in FFT3d computations over CPU for larger FFT3d designs."}],"date_created":"2018-11-07T16:08:32Z","publisher":"Universität Paderborn","title":"Accelerating Molecular Dynamic Simulations by Offloading Fast Fourier Transformations to FPGA","year":"2018"},{"type":"conference","status":"public","user_id":"15278","department":[{"_id":"27"},{"_id":"518"},{"_id":"61"}],"project":[{"name":"HighPerMeshes","_id":"33","grant_number":"01|H16005A"},{"grant_number":"160364472","name":"SFB 901","_id":"1"},{"_id":"4","name":"SFB 901 - Project Area C"},{"name":"SFB 901 - Subproject C2","_id":"14","grant_number":"160364472"}],"_id":"1588","file_date_updated":"2018-11-02T14:45:05Z","has_accepted_license":"1","citation":{"ama":"Kenter T, Mahale G, Alhaddad S, et al.

In computational sciences, often more advanced methods are employed that promise better stability, convergence, locality and scaling. Unstructured meshes are shown to be more effective and more accurate, compared to regular grids, in representing computation domains of various shapes. Using unstructured meshes, the discontinuous Galerkin method preserves the ability to perform explicit local update operations for simulations in the time domain. In this work, we investigate FPGAs as target platform for an implementation of the nodal discontinuous Galerkin method to find time-domain solutions of Maxwell's equations in an unstructured mesh. When maximizing data reuse and fitting constant coefficients into suitably partitioned on-chip memory, high computational intensity allows us to implement and feed wide data paths with hundreds of floating point operators. By decoupling off-chip memory accesses from the computations, high memory bandwidth can be sustained, even for the irregular access pattern required by parts of the application. Using the Intel/Altera OpenCL SDK for FPGAs, we present different implementation variants for different polynomial orders of the method. In different phases of the algorithm, either computational or bandwidth limits of the Arria 10 platform are almost reached, thus outperforming a highly multithreaded CPU implementation by around 2x.","lang":"eng"}],"language":[{"iso":"eng"}],"ddc":["000"],"keyword":["tet_topic_hpc"],"quality_controlled":"1","year":"2018","date_created":"2018-03-22T10:48:01Z","publisher":"IEEE","title":"OpenCL-based FPGA Design to Accelerate the Nodal Discontinuous Galerkin Method for Unstructured Meshes"},{"abstract":[{"lang":"eng","text":"We present the submatrix method, a highly parallelizable method for the approximate calculation of inverse p-th roots of large sparse symmetric matrices which are required in different scientific applications. Following the idea of Approximate Computing, we allow imprecision in the final result in order to utilize the sparsity of the input matrix and to allow massively parallel execution. For an n x n matrix, the proposed algorithm allows to distribute the calculations over n nodes with only little communication overhead. The result matrix exhibits the same sparsity pattern as the input matrix, allowing for efficient reuse of allocated data structures.\r\n\r\nWe evaluate the algorithm with respect to the error that it introduces into calculated results, as well as its performance and scalability. We demonstrate that the error is relatively limited for well-conditioned matrices and that results are still valuable for error-resilient applications like preconditioning even for ill-conditioned matrices. We discuss the execution time and scaling of the algorithm on a theoretical level and present a distributed implementation of the algorithm using MPI and OpenMP. We demonstrate the scalability of this implementation by running it on a high-performance compute cluster comprised of 1024 CPU cores, showing a speedup of 665x compared to single-threaded execution."}],"publication":"Proc.
