This year, we and the other seven NHR centers were part of the\u202f<a href=\"https:\/\/www.nhr-verein.de\/\">NHR Alliance<\/a> booth. The NHR Alliance was one of 158 exhibitors, with 147 exhibiting onsite. 3.015 participants attended this year\u2019s ISC, setting a new post-pandemic record. ISC 2024 will be held May 12-17 in Hamburg, Germany.<\/p>\n<p>In addition to the booth, we contributed tutorials, paper presentations and our so-called Sofa Talks. We established the Sofa Talks at ISC last year and continued these talks this year. We invited guests to discuss relevant topics with them in a relaxed, personal atmosphere in our Sofa Corner.<\/p>\n<p><!--more--><\/p>\n<h3><span style=\"color: #00549f;\"><strong><br \/>\nOur Activities<\/strong>\u00a0<\/span><\/h3>\n<p>On Sunday, <a href=\"https:\/\/www.itc.rwth-aachen.de\/cms\/it-center\/IT-Center\/Profil\/Team\/~epvp\/Mitarbeiter-CAMPUS-\/?allou=1&amp;gguid=0xAAB88A63E195DA4E98AE006286D9839F&amp;lidx=1\">Dr. Christian Terboven<\/a> from our <a href=\"https:\/\/www.nhr4ces.de\/cross-sectional-groups\/csg-parallelism-and-performance\/\">CSG Parallelism and Performance<\/a> presented the tutorial Advanced OpenMP: Performance and 5.2 Features, which explored the implications of possible OpenMP parallelization strategies, both in terms of correctness and performance. It reviewed the basics of OpenMP programming and discussed language features in-depth, with emphasis on advanced features like vectorization and compute acceleration.<\/p>\n<p>And while Dmytro Povaliaiev was part of the Workshop \u2013 HPC I\/O in the Data Center \u2013 Transfer Learning Workflow for I\/O Bandwidth Prediction on Thursday, Marcel Kr\u00fcger\u202fpresented the work\u202f&#8221;A Case Study on Providing Accessbility-Focused In-Transit Architectures for Neural Network Simulation and Analysis\u201c at the Workshop on In Situ Visualization (#WOIV).\u202fThe paper describes how\u202four <a href=\"https:\/\/www.nhr4ces.de\/cross-sectional-groups\/csg-visualization\/\">CSG\u202fVisualization<\/a>\u202fprovides in-situ\/in-transit capabilities for analysis and visualization of simulation data which allows users to get early feedback, steering possibilities and efficient access to analysis and visualization. In addition to presenting the paper, Marcel also participated in the panel discussion with other experts to discuss the future of In Situ solutions.<\/p>\n<h3><span style=\"color: #00549f;\"><strong><br \/>\nThe Sofa Talks Were a Great Success<\/strong>\u00a0<\/span><\/h3>\n<p>On Monday, <a href=\"https:\/\/www.itc.rwth-aachen.de\/cms\/it-center\/IT-Center\/Profil\/Team\/~epvp\/Mitarbeiter-CAMPUS-\/?allou=1&amp;gguid=0xAF982E757988F54C8174F49392D637D9&amp;lidx=1\">Dr. Tim Gerrits<\/a> from our CSG Visualization kicked off the Sofa Talks on the NHR booth. He talked about\u202frecent challenges in visualization for HPC\u202fwith his guests\u202fFrancois Mazen (Kitware),\u202fDave Pugmire,\u202fMichael B\u00f6ttinger,\u202fJens Henrik G\u00f6bbert,\u202fMarcel Kr\u00fcger,\u202fMartin Aum\u00fcller,\u202fJames Kress, and\u202fUwe W\u00f6ssner.\u202fIn a relaxed atmosphere, the visualization experts discussed various strategies for simplifying access to visualization. New connections were made and the discussions continued beyond this Sofa Talk.,\u202fMichael B\u00f6ttinger,\u202fJens Henrik G\u00f6bbert,\u202fMarcel Kr\u00fcger,\u202fMartin Aum\u00fcller,\u202fJames Kress, and\u202fUwe W\u00f6ssner.\u202fIn a relaxed atmosphere, the visualization experts discussed various strategies for simplifying access to visualization. New connections were made, and the discussions continued beyond this Sofa Talk.<\/p>\n<p>Dr. Christian Terboven hosted our second Sofa Talk: NHR: Benchmarks + TCO on Tuesday. While HPL and Stream benchmarks have a long tradition in HPC cluster procurements and acceptance tests, they do not reflect the real-world usage of an HPC cluster that often runs multi-node and\/or memory-bound jobs. To evaluate the real value of an HPC system, relevant and real-world applications should be included in the request for proposals. The group discussed current HPC procurement processes in NHR. The goal is to support the corresponding future project in establishing methodologies and best practices for NHR-specific benchmarking and TCO modeling.<\/p>\n<h3><span style=\"color: #00549f;\"><strong>OpenMP &#8211; What&#8217;s There and What&#8217;s to Come<\/strong><\/span><\/h3>\n<p>Also on tuesday, Christian also participated in the Birds of a Feather (BOF) session titled The OpenMP API v5.2 and v6.0 &#8211; What&#8217;s There and What&#8217;s to Come. Members of the OpenMP language committee \u2013 the committee developing the next version of the OpenMP parallel programming standard \u2013 presented the active development towards OpenMP 6.0 and were available to answer questions from the audience.<\/p>\n<p>On Wednesday, the last day of the exhibition, <a href=\"https:\/\/www.itc.rwth-aachen.de\/cms\/it-center\/IT-Center\/Profil\/Team\/~epvp\/Mitarbeiter-CAMPUS-\/?allou=1&amp;gguid=0x82E13C6BCD761743BD4B879DA74CEF7E&amp;lidx=1\">Marc-Andr\u00e9 Hermanns<\/a> invited his guests to discuss Teaching Advanced MPI, while <a href=\"informatik.tu-darmstadt.de\/sc\/fg\/people\/staff_details_sc_17600.en.jsp\">Dr. Benjamin Juhl<\/a> \u2013 both from our infrastructure team \u2013 hosted his Sofa Talk regarding Software licenses in NHR. NHR centers aim to attract users from all of Germany, and provide them with the expertise outlined in the center\u2019s research expertise profile \u2013 e.g. atomistic simulations or deep learning. This expertise of course extends to the software stack provided at the NHR clusters. However traditional license agreements for university software have in the past often limited the allowed users to members of that organization. The goal of this sofa talk was to exchange experience with adjusting current license agreements, and discuss requirements for negotiating future license agreements.<\/p>\n<p>We enjoyed the exchange at ISC and look forward to further developments in the HPC world.<\/p>\n<h3><span style=\"color: #00549f;\">Impressions of the ISC<\/span><\/h3>\n<div id=\"attachment_15985\" style=\"width: 310px\"
