Custom hardware designs significantly accelerate the execution of these algorithms. In this article, we demonstrate a high-performance B&B implementation on FPGAs. First, we identify general elements of B&B algorithms and describe their implementation as a finite state machine. Then, we introduce workers that autonomously cooperate using work stealing to allow parallel execution and full utilization of the target FPGA. Finally, we explore advantages of instance-specific designs that target a specific problem instance to improve performance.\r\n\r\nWe evaluate our concepts by applying them to a branch and bound problem, the reconstruction of corrupted AES keys obtained from cold-boot attacks. The evaluation shows that our work stealing approach is scalable with the available resources and provides speedups proportional to the number of workers. Instance-specific designs allow us to achieve an overall speedup of 47 × compared to the fastest implementation of AES key reconstruction so far. Finally, we demonstrate how instance-specific designs can be generated just-in-time such that the provided speedups outweigh the additional time required for design synthesis."}],"publication":"ACM Transactions on Reconfigurable Technology and Systems (TRETS)","language":[{"iso":"eng"}],"keyword":["coldboot"],"ddc":["000"]},{"status":"public","type":"conference","file_date_updated":"2018-11-02T15:02:28Z","_id":"1592","project":[{"grant_number":"160364472","_id":"1","name":"SFB 901"},{"name":"SFB 901 - Project Area C","_id":"4"},{"_id":"14","name":"SFB 901 - Subproject C2","grant_number":"160364472"},{"_id":"33","name":"HighPerMeshes","grant_number":"01|H16005A"},{"name":"Performance and Efficiency in HPC with Custom Computing","_id":"32","grant_number":"PL 595/2-1 / 320898746"},{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"department":[{"_id":"27"},{"_id":"518"},{"_id":"61"}],"user_id":"15278","citation":{"chicago":"Kenter, Tobias, Jens Förstner, and Christian Plessl. “Flexible FPGA Design for FDTD Using OpenCL.” In <i>Proc.

In this work, we evaluate the extent of this promise. To this end, we present a parameterized FDTD implementation for photonic microcavity simulations. Our design can trade-off different forms of parallelism and works for two independent OpenCL-based FPGA design flows. Hence, we can target FPGAs from different vendors and different FPGA families. We describe how we used pre-processor macros to achieve this flexibility and to work around different shortcomings of the current tools. Choosing the right design configurations, we are able to present two extremely competitive solutions for very different FPGA targets, reaching up to 172 GFLOPS sustained performance. With the portability and flexibility demonstrated, code developers not only avoid vendor lock-in, but can even make best use of real trade-offs between different architectures.","lang":"eng"}],"file":[{"relation":"main_file","success":1,"content_type":"application/pdf","file_name":"08056844.pdf","access_level":"closed","file_id":"5291","file_size":230235,"creator":"ups","date_created":"2018-11-02T15:02:28Z","date_updated":"2018-11-02T15:02:28Z"}],"publication":"Proc.

The influence of different parametrizations of the exchange-correlation functional on the investigated properties is analyzed in detail, and the results are compared to available experimental data. We argue that the PBEsol and AM05 generalized gradient approximations as well as the RTPSS meta-generalized gradient approximation yield consistently accurate structural data for both the external and internal degrees of freedom and are overall superior to the local-density approximation or other conventional generalized gradient approximations for the structural characterization of KNbO3. Band-structure calculations using a HSE-type hybrid functional further indicate significant near degeneracies of band-edge states in all phases which are expected to be relevant for the optical response of the material.","lang":"eng"}],"file":[{"date_updated":"2020-08-30T14:37:31Z","date_created":"2020-08-28T09:27:19Z","title":"Consistent atomic geometries and electronic structure of five phases of potassium niobate from density-functional theory","description":"Creative Commons Attribution 4.0 International Public License (CC BY 4.0)","access_level":"open_access","file_id":"18538","relation":"main_file","creator":"schindlm","file_size":985948,"file_name":"3981317.pdf","content_type":"application/pdf"}],"publication":"Advances in Materials Science and Engineering","ddc":["530"],"language":[{"iso":"eng"}],"external_id":{"isi":["000394873300001"]},"year":"2017","quality_controlled":"1","title":"Consistent atomic geometries and electronic structure of five phases of potassium niobate from density-functional theory","publisher":"Hindawi","date_created":"2019-05-29T07:48:32Z","status":"public","type":"journal_article","article_type":"original","article_number":"3981317","isi":"1","file_date_updated":"2020-08-30T14:37:31Z","project":[{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"},{"_id":"53","name":"TRR 142"},{"name":"TRR 142 - Project Area B","_id":"55"},{"_id":"69","name":"TRR 142 - Subproject B4"},{"name":"Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"_id":"10023","user_id":"16199","department":[{"_id":"295"},{"_id":"296"},{"_id":"230"},{"_id":"429"},{"_id":"15"},{"_id":"35"},{"_id":"27"}],"citation":{"ama":"Schmidt F, Landmann M, Rauls E, et al.
