SUMMARY:aiXcelerate 2017
DESCRIPTION:Der Eintrag ist nur auf English verfügbar.  \n\n\n\n\n\n  \nHPC Tuning Workshop\nTue\, Dec 5  – Thu\, Dec 7\, 2017\nIT Center\nRWTH Aachen University\nsponsored by: \n  \n\n\n\n\n\n\nIntroduction\nThis year’s aiXcelerate HPC Tuning Workshop will focus on two topics: \n\nMPI+OPA: Tuning of parallel programs employing message passing with MPI and running on the Intel OmniPath fabric.\nKNL: Tuning for Intel’s Xeon Phi new many core processor\n\nThe nodes of Claix\, the latest RWTH Aachen University’s Supercomputer\, are equipped with Intel Broadwell processors and connected through a network with the Intel OmniPath architecture (OPA). Claix has recenlty been complemented by 16 nodes containing an Intel’s Xeon Phi 7210 processor – code named Knights Landing (KNL). At the Jülich Supercomputer Centre a cluster called „Booster“ will soon be installed which will contain Intel’s Xeon Phi many core 7250-F processors and an Intel OmniPath fabric. The KNL nodes at Aachen can well be used to prepare and tune programs for Booster. \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 will consist of presentations open to a broader auditorium and of a hands-on tuning workshop for a limited number of selected compute projects.\nPresentations will be given in English. \nWe are proud to announce Michael Klemm and Christopher Dahnken\, two HPC performance experts from Intel\, who will give presentations and support you with your tuning efforts. They will be complemented by experts of the HPC Team of the IT Center at RWTH Aachen University. \nMaterials\n\nAgenda\nMichael Klemm (Intel): MPI & ITAC\nDirk Schmidl (RWTH): NonIntel Tools\nHristo Iliev (RWTH): Open MPI\nPaul Kapinos (RWTH): RWTH Compute Cluster environment\nChristopher Dahnken (Intel): Intel Xeon Phi Architecture\nChristopher Dahnken (Intel): OpenMP SIMD\nMichael Klemm (Intel): VTune\, also for MPI\n\naiXcelerate – presentations\n\nMPI+OPA: On Tue morning\, Dec 5\, we will start at 10:00 with presentations on MPI programming and tuning using Intel MPI on the OmniPath fabric (OPA).\nPlease  register here for the presentations on MPI+OPA\nKNL: On Wed morning\, Dec 6\, we will start at 10:00 with presentations on Xeon Phi (KNL) programming and tuning using Intel compiler and tools.\nPlease  register here for the presentations on KNL\n\naiXcelerate – tuning workshop\nIn the afternoon after the presentations on Tue and Wed and also throughout Thu\, Dec 7\, we provide you with hands-on opportunity to adapt\, analyze and tune your performance critical applications on Claix\, with its Broadwell and Xeon Phi processors connected through the OmniPath Fabric. \nParticipation in the presentations is a prerequisite for participation in tuning workshop. \nAttendees are kindly requested to prepare and bring in their own code. It is assumed that you have 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 would like to ask you to prepare one or more test cases that reflect typical production runs\, but do not take too long to execute – in the ideal case\, a run should not take more than 5 to 10 minutes to finish. Members of the local HPC team will support  every accepted project in porting the code to Claix. By the start of the workshop the code should be ready to be analyzed. \nIf you plan to participate in the tuning activities please contact us by sending an email to hpcevent@itc.rwth-aachen.de. \nWorkshop participants are invited to take part in the social dinner on Wednesday evening in Restaurant Palladion .-please note if you like to take part in your registration. Thank you. \n\n\n\nCosts\n\nAttendance is free of charge and supported by our sponsors.\nTravel and accommodation are at your 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 \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. \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\n\nTechnical Information for Tuning Workshop Participants to get prepared for KNL\nWorkshop participants with an interest in tuning for KNL can prepare their jobs on the KNL systems: \nKNL login node: \nlogin-knl.hpc.itc.rwth-aachen.de\nJob commands for submitting an LSF job to the 15 KNL batch nodes: \n#BSUB -P hpclab\n#BSUB -R knl\n#BSUB -m c64m208k\nPlease contact us and send us your HPC account so we can add you to the project „hpclab“ for the workshop. \nYou can find some information on tuning for KNL here. \nContact\n\nPaul Kapinos\, Dieter an Mey\nE-mail: hpcevent@itc.rwth-aachen.de
