The course’s objectives are to familiarize architecture students with computational geometry, foster computational thinking that stays relevant over time, and promote democratized design tools through computation. Over a semester, we taught students to work directly on coordinates or numerical representations by utilizing 3- Dimensional (3D) computer graphics programming rather than learning 3D modeling software that rapidly goes out of style. This paper outlines our teaching methods to introduce the technology stack, design algorithm development, open-source or free tools implementation, and user experience – interface design. This paper also reviews the students’ final projects to deliver interactive web-browser applications for architectural design of varied scales and compares them according to four evaluation parameters. The paper culminates with the project's critical assessment and students' feedback to evaluate our approach and suggest an outlook for future development. https://puma.ub.uni-stuttgart.de/bibtex/22f5e7b42c3561b52990a8ffa938f13dc/dschwachhoferdschwachhofer2024-09-12T16:35:30+02:00Artificial Intelligence Emerging Programming sciences, Languages Technologies (cs.SE), FOS: Engineering sciences (cs.PL), and (cs.ET), Computer Software (cs.AI), information <span data-person-type="author" class="authorEditorList "><span><span itemtype="http://schema.org/Person" itemscope="itemscope" itemprop="author"><a title="Denis Schwachhofer" itemprop="url" href="/person/17bc3000dd843e1572c21bc0959fb0f75/author/0"><span itemprop="name">D.

Existing techniques restrict the application to relatively low dimensions since the discretizations typically suffer from the curse of dimensionality. In this paper we introduce a novel approximation technique for the value function of an infinite horizon optimal control. The method is based on solving optimal open loop control problems on a finite horizon with a sampling of the global value function along the generated trajectories. For the interpolation we choose a kernel orthogonal greedy strategy, because these methods are able to produce extreme sparse surrogates and enable rapid evaluations in high dimensions.

Compared to the traditional hybrid approach of MPI plus OpenMP, a new, but promising hybrid approach of MPI plus MPI-3 shared-memory extensions (MPI+MPI) is gaining attraction. We describe an algorithmic approach for collective operations (with allgather and broadcast as concrete examples) in the context of hybrid MPI+MPI, so as to minimize memory consumption and memory copies. With this approach, only one memory copy is maintained and shared by on-node processes. This allows the removal of unnecessary on-node copies of replicated data that are required between MPI processes when the collectives are invoked in the context of pure MPI. We compare our approach of collectives for hybrid MPI+MPI and the traditional one for pure MPI, and also have a discussion on the synchronization that is required to guarantee data integrity. The performance of our approach has been validated on a Cray XC40 system (Cray MPI) and NEC cluster (Open MPI), showing that it achieves comparable or better performance for allgather operations. We have further validated our approach with a standard computational kernel, namely distributed matrix multiplication, and a Bayesian Probabilistic Matrix Factorization code.https://puma.ub.uni-stuttgart.de/bibtex/288b6af3d8c052efd8b6d922f97e16038/huanzhouhuanzhou2020-07-28T11:45:45+02:00MPI collective communications hybrid myown programming <span data-person-type="author" class="authorEditorList "><span><span itemtype="http://schema.org/Person" itemscope="itemscope" itemprop="author"><a title="Huan Zhou" itemprop="url" href="/person/1aff8c6eff5f6e8afc7945834cb46afd3/author/0"><span itemprop="name">H.

In almost all cases the application program has the form of a text based source code, which has inherent drawbacks (in terms of complexity and ease of development) when compared to the graphical approaches seen in general purpose software engineering. These graphical programming approaches have not been developed, having industrial robots in mind. In this paper a behavior trees based approach for creating and representing source code for robotic applications is proposed. The software architecture and an experimental implementation of the developed programming method is presented and a validation using a common assembly task is shown.https://puma.ub.uni-stuttgart.de/bibtex/200e71607cd89c36f3f5bb856e79e7b39/c.niethammerc.niethammer2017-12-12T10:44:52+01:00debugging hlrs parallel performance programming spmt toosl <span data-person-type="editor" class="authorEditorList "><span><span itemtype="http://schema.org/Person" itemscope="itemscope" itemprop="editor"><a title="Andreas Knüpfer" itemprop="url" href="/person/1a34d7850fc52c43c6bb1a3e4548dbc6f/editor/0"><span itemprop="name">A.

Proceedings1--12591 TFLOPS Multi-trillion Particles Simulation on SuperMUC2013dynamics highly molecular parallel programming scalable simulation simulations vectorization Anticipating large-scale molecular dynamics simulations (MD) in nano-fluidics, we conduct performance and scalability studies of an optimized version of the code ls1 mardyn. We present our implementation requiring only 32 Bytes per molecule, which allows us to run the, to our knowledge, largest MD simulation to date. Our optimizations tailored to the Intel Sandy Bridge processor are explained, including vectorization as well as shared-memory parallelization to make use of Hyperthreading. Finally we present results for weak and strong scaling experiments on up to 146016 Cores of SuperMUC at the Leibniz Supercomputing Centre, achieving a speed-up of 133k times which corresponds to an absolute performance of 591.2 TFLOPS.
