SUMMARY:aiXcelerate 2018
DESCRIPTION:Der Eintrag ist nur auf English verfügbar. \n\n\n\n\n  \nHPC Tuning Workshop\nMon\, Dec 3  – Wed\, Dec 5\, 2018\nIT Center\nRWTH Aachen University\nsponsored by: \n  \n\n\n\n\n\n\nIntroduction\naiXcelerate HPC Tuning Workshop had the focus on the Intel Skylake (SKK) Microarchitecture\, SIMD programming and performance tuning using Likwid\, Intel VTune/Amplifier and Intel Advisor. \nThe nodes of CLAIX-2018\, the latest RWTH Aachen University’s Supercomputer\, were equipped with Intel Skylake processors and connected through a network with the Intel OmniPath architecture (OPA). It was a major extension of CLAIX-2016 system equipped with Intel  Broadwell processors and connected through OPA\, too. \nResearchers from FZ Jülich and RWTH with high demand for compute power can apply for resources on these systems as part of the JARA-HPC partition (>>> more… ).\nResearchers from all over Germany can apply for resources on Claix (>>> more… ). \nThe workshop consisted of presentations open to a broader auditorium and of a hands-on tuning workshop for a limited number of selected computing projects.\nPresentations was  given in English. \nWe awere proud to announce Michael Klemm and Christopher Dahnken\, two HPC performance experts from Intel\, who gave presentations and support your tuning efforts. Furthermore\, a presentation on detecting performance limiting factors with hardware monitoring using likwid was given by Thomas Gruber (born Röhl) main developer of the Likwid tool. Experts of the HPC Team of the IT Center at RWTH Aachen University assisted in your tuning activietes as well. \nMaterials\n\nAgenda\nSandra Wienke (RWTH): aiXcelerate Welcome & CLAIX-2018 Overview\nMarcus Wagner\, Paul Kapinos (RWTH): SLURM and Modules for CLAIX-2018\nJonas Hahnfeld (RWTH): Performance Monitoring on CLAIX\nMichael Klemm (Intel): Skylake Architecture\nMichael Klemm (Intel): Skylake Performance Considerations\nMichael Klemm (Intel): Intel VTune Amplifier\nThomas Gruber (FAU Erlangen): LIKWID\, Detecting Performance Limiting Factors with Hardware Monitoring\n\n\nRegistration\nClosed \naiXcelerate 2018 – Presentations\n\nDec 3\, 11:00-13:00 – On Mon morning\, Dec 3\, we started at 11:00 with presentations on the new CLAIX-2018 cluster and the Skylake processor microarchitecture\nDec 3\, 14:00-15:00 – After lunch on Monday\, we continued with presentations on SIMD programming and performance optimization.\nDec 4\, 11:00-13:00 – On Tuesday morning\, Dec 4\, we started at 11:00 with presentations on Likwid\, Intel VTune/Amplifier and Advisor.\n\naiXcelerate 2018 – Tuning Workshop\nAfter the presentations on Mon Dec 3\, on Tue Dec4\, and also throughout Wed\, Dec 5\, we provided you with hands-on opportunity to adapt\, analyze and tune your performance critical applications on CLAIX\, with its Skylake (and Broadwell) processors connected with the Intel OmniPath (OPA) fabric. \nParticipation in the presentations was a prerequisite for participation in tuning workshop. \nAttendees were kindly requested to prepare and bring in their own code. It was assumed that you had a good working knowledge with MPI and/or OpenMP\, and C/C++ or Fortran\, whatever your compute project employs. To maximize the efficiency of the workshop\, we asked the participants to prepare one or more test cases that reflected typical production runs\, but did not take too long to execute – in the ideal case\, a run didnot  take more than 5 to 10 minutes to finish. Members of the local HPC team supported every accepted project in porting the code to Claix. By the start of the workshop the code was asked be ready to be analyzed. \nFurthermore\, each participant (or participating group) was kindly asked to shortly present their project (1-2 slides) at the beginning of the tuning workshop and also shortly present the outcome of the tuning efforts at the end of the workshop. \nParticipants who were intested in the tuning activities contacted us by sending an email to hpcevent@itc.rwth-aachen.de. \nWorkshop participants were invited to take part in the social dinner on Tuesday\, Dec 4 in the restaurant Palladion. \n\n\n\nCosts\n\nAttendance was free of charge and supported by our sponsors.\nTravel and accommodation were at participants own expense. \nLinks to previous Events\n\n\nNehalem Tuning Workshop 2009 (n/a)\n\nHPC Tuning Workshop 2010\naiXcelerate – HPC Tuning Workshop 2011\naiXcelerate – HPC Tuning Workshop 2012 \naiXcelerate – HPC Tuning Workshop 2013 \naiXcelerate – HPC Tuning Workshop 2014 \naiXcelerate – HPC Tuning Workshop 2015 \naiXvectorize – Vectorization and Tuning Workshop 2015\naiXvectorize – Vectorization and Tuning Workshop 2016\naiXcelerate – HPC Tuning Workshop 2016  \naiXcelerate- HPC Tuning Workshop 2017\n\n\nFeedback\n\nAfter the event we will ask you to provide your feedback. You will find a link to the web form here.\nWe depend on your input in order to improve our offerings.\n \n\nTravel Information\nIf required\, please make your own hotel reservation.You can find some popular hotels listed here. You may find a complete list of hotels on the web pages of the Aachen Tourist Service. We recommend that you try to book a room in the „Novotel Aachen City„\, “ Mercure am Graben“ or „Aachen Best Western Regence“ hotels. These are adequate hotels with reasonable prices at a walking distance (20-30 minutes) to the IT Center through the old city of Aachen. An alternative is the hotel „IBIS Aachen Marschiertor“ which is close to the main station\, which is convenient if you are travelling by train and also want to commute to the IT Center by train (3 trains per hour\, 2 stops) \nPlease\, download a sketch of the city (pdf\, 415 KB) with some points of interest marked.\nYou may find a description of how to reach us by plane\, train or car here.\nBus route 33 connects the city and the stop „Mies-van-der-Rohe-Straße“ every 15 minutes.\nTrains between Aachen and Düsseldorf stop at „Aachen West“ station which is a 5 minutes walk away from the IT Center.\nFrom the bus stop and the train station just walk uphill the „Seffenter Weg“. The first building on the left hand side at the junction with „Kopernikusstraße“ is the IT Center.\n\nThe weather in Aachen is usually unpredictable. It is always a good idea to carry an umbrella. If you’ll bring one\, it might be sunny! \n\n\nTechnical Information for Tuning Workshop Participants\nWorkshop participants should have an account at the HPC Cluster in Aachen. Participants were asked not to bring in their own laptop. The IT Center provided a lend device; in this case please be equipped also with the ‚PC Pool‚ account (get it via Selfservice). \nPlease contact us and send us your HPC account (like ab123456) so we can add you to the project „hpclab“ for the workshop. \nContact\n\nPaul Kapinos\, Dieter an Mey\nE-mail: hpcevent@itc.rwth-aachen.de\n\n\n\n\n\n \n\n\n\n\n\n  \nHPC Tuning Workshop\nMon\, Dec 3  – Wed\, Dec 5\, 2018\nIT Center\nRWTH Aachen University\nsponsored by: \n  \n\n\n\n\n\n\nIntroduction\naiXcelerate HPC Tuning Workshop had the focus on the Intel Skylake (SKK) Microarchitecture\, SIMD programming and performance tuning using Likwid\, Intel VTune/Amplifier and Intel Advisor. \nThe nodes of CLAIX-2018\, the latest RWTH Aachen University’s Supercomputer\, were equipped with Intel Skylake processors and connected through a network with the Intel OmniPath architecture (OPA).
