The most important functions of this type are piece-wise linear. For optimization problems with uniform sparsity of corresponding linear operators, we suggest a very efficient implementation of subgradient iterations, which total cost depends logarithmically in the dimension. This technique is based on a recursive update of the results of matrix\/vector products and the values of symmetric functions. It works well, for example, for matrices with few nonzero diagonals and for max-type functions.\u003C\/p\u003E\u003Cp\u003EWe show that the updating technique can be efficiently coupled with the simplest subgradient methods, the unconstrained minimization method by B. Polyak, and the constrained minimization scheme by N. Shor. Similar results can be obtained for a new non- smooth random variant of a coordinate descent scheme.

I will describe a sustainable software stack for parallel analysis of very large graphs. The layered software architecture combines performance, customizability, and conceptual simplicity though separation of concerns. I will first focus on the parallel backend, the Combinatorial BLAS, which implements state-of-the-art algorithms for sparse matrix primitives that serve as parallel building blocks for tightly-coupled graph computations. I will present the algorithmic innovations that make the primitives scalable, and the algebraic semiring model that is fundamental to the customizability of the Combinatorial BLAS. Several graph kernels that are implemented by composing a handful of the Combinatorial BLAS primitives scale up to tens of thousands of cores on distributed memory architectures, surpassing specialized implementations. I will then outline the architecture and capabilities of the Python based frontend, the Knowledge Discovery Toolbox, and describe several applications.

Based upon a vast number of experimental data, constantly improving research tools, and deepening theoretical understanding of the structure of crystalline materials no revolution was anticipated in our understanding the atomic order of solids.\u003C\/p\u003E\u003Cp\u003EHowever, such revolution did happen with the discovery of the Icosahedral phase, the first quasi-periodic crystal (QC) in 1982, and its announcement in 1984 [1, 2].\u0026nbsp; QCs are ordered materials, but their atomic order is quasiperiodic rather than periodic, enabling formation of crystal symmetries, such as icosahedral symmetry, which cannot exist in peri-odic materials.\u0026nbsp; The discovery created deep cracks in this paradigm, but the acceptance by the crystallographers\u0027 community of the new class of ordered crystals did not happen in one day.\u0026nbsp; In fact it took almost a decade for QC order to be accepted by most crystallographers. The official stamp of approval came in a form of a new definition of \u201cCrystal\u201d by the International Union of Crystallographers. The paradigm that all crystals are periodic has thus been changed. It is clear now that although most crystals are ordered and periodic, a good number of them are ordered and quasi-periodic. \u003C\/p\u003E\u003Cp\u003EWhile believers and nonbelievers were debating, a large volume of experimental and the-oretical studies was published, a result of a relentless effort of many groups around the world.

To identify the optimal lattice structures and the\noptimal algorithm combinations, we use several statistical tools to\nmodel the unknown response functions of the tuning parameters. Tools\narising in design and analysis of computer experiments will be\ndiscussed to show the details of the schemes. Promising numerical\nresults will also be presented to justify the proposed schemes.\n\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Parameters Auto-Tuning in Three Dimensional Photonic Crystal Simulations"}],"uid":"27187","created_gmt":"2012-02-08 16:43:58","changed_gmt":"2016-10-08 01:58:00","author":"Anita Race","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2012-02-13T10:00:00-05:00","event_time_end":"2012-02-13T11:00:00-05:00","event_time_end_last":"2012-02-13T11:00:00-05:00","gmt_time_start":"2012-02-13 15:00:00","gmt_time_end":"2012-02-13 16:00:00","gmt_time_end_last":"2012-02-13 16:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"1242","name":"School of Industrial and Systems Engineering (ISYE)"}],"categories":[],"keywords":[],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003EHost: Jeff Wu \u003Ca href=\u0022mailto:jeffwu@isye.gatech.edu\u0022\u003E\u0026lt;jeffwu@isye.gatech.edu\u0026gt;\u003C\/a\u003E\n\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
