Hands on work will be d one in pairs so if you don’t have a laptop you might work with a colleag ue. \n\nCourse language is English.\n\nRegistration\n\nThe maximum number of participants is 30. \n\nRegistrations will be evaluated on a first-come \, first-served basis. GRNET is responsible for the selection of the parti cipants on the basis of the training requirements and the technical skills of the candidates. GRNET will also seek to guarantee the maximum possibl e geographical coverage with the participation of candidates from many cou ntries.\n\nVenue\n\nGRNET headquarters\n\nAddress: 2nd  Floor\, 7\, Kifis ias Av. GR 115 23 Athens\n\nInformation on how to reach GRNET headquarters ia available on GRNET website: https://grnet.gr/en/contact-us/  \n\nAcc ommodation options near GRNET can be found at: https://grnet.gr/wp-content /uploads/sites/13/2015/11/Hotels-near-GRNET-en.pdf\n\nARIS - System Inform ation\n\nARIS is the name of the Greek supercomputer\, deployed and operat ed by GRNET (Greek Research and Technology Network) in Athens. ARIS consis ts of 532 computational nodes seperated in four “islands” as listed he re:\n\n\n \n 426 thin nodes: Regular compute nodes without accelerat or.\n \n \n 44 gpu nodes: “2 x NVIDIA Tesla k40m” accelerated nodes.\n \n \n 18 phi nodes: “2 x INTEL Xeon Phi 7120p” acce lerated nodes.\n \n \n 44 fat nodes: Fat compute nodes have large r number of cores and memory per core than a thin node.\n \n\n\nAll the nodes are connected via Infiniband network and share 2PB GPFS storage.The infrastructure also has an IBM TS3500 library of maximum storage capacity of about 6 PB. Access to the system is provided by two login nodes. \n\nA bout Tutors\n\nDr. Dellis (Male) holds a B.Sc. in Chemistry (1990) and PhD in Computational Chemistry (1995) from the National and Kapodistrian Univ ersity of Athens\, Greece. He has extensive HPC and grid computing experie nce. He was using HPC systems in computational chemistry research projects on fz-juelich machines (2003-2005). He received an HPC-Europa grant on BS C (2009). In EGEE/EGI projects he acted as application support and VO soft ware manager for SEE VO\, grid sites administrator (HG-02\, GR-06)\, NGI_G RNET support staff (2008-2014). In PRACE 1IP/2IP/3IP/4IP/5IP he was involv ed in benchmarking tasks either as group member or as BCO (2010-2018). Cur rently he is leader of the HPC team at GRNET S.A.\n\nKyriakos Ginis receiv ed his Diploma in Electrical and Computer Engineering in 2003 from the Nat ional Technical University of Athens\, Greece. Between 2004 and 2014 he pa rticipated in the european projects EGEE I/II/III and EGI as a grid site a dministrator of the HellasGrid sites HG-01-GRNET\, HG-06-EKT and HG-08-Oke anos. Since 2014 he works at GRNET as a system administrator of the ARIS H PC system\, primarily responsible for hardware\, operating systems and fil e/storage systems. He continues maintaining the HellasGrid sites HG-06 and HG-08\, and supports other GRNET services such as the unique and persiste nt identifiers (PID)\nservice\, also part of the EUDAT project.\n\nNikolou tsakos Nikolaos holds a diploma of Engineering in Computer Engineering and Informatics (2014) from the University of Patras\, Greece. From 2015 he w orks as software engineer at GRNET S.A. where he is part of the user appli cation support team for the ARIS HPC system. He has been involved in major national and European projects\, such as PRACE and EUDAT. His main resear ch interests include parallel programming models\, co-processor programmin g using GPUs and Intel Xeon Phis.\n\nDr Aristeidis Sotiropoulos received his BSc in Computer Science in 1998 from the University of Crete\, Greece and his PhD in Parallel Processing and Cluster Computing in 2004 from the National Technical University of Athens\, Greece. His interests mainly foc us on the fields of Large Scale Computing &\; Storage Systems\, System Software for Scalable High Speed Interconnects for Computer Clusters and A dvanced Microprocessor Architectures. He has published several scientific papers in international journals and conference proceedings. He has receiv ed the IEEE IPDPS 2001 best paper award for the paper "Minimizing Completi on Time for Loop Tiling with Computation and Communication Overlapping". H e has worked in several European and National R&\;D programs in the fie ld of High Performance Computing\, Grid Computing\, Cloud Computing and St orage. In 2013\, he was appointed as the Head of Operations and Financial Management Services\, in charge of 15 people. Currently\, he is managing E C projects at GRNET SA\, the Greek NREN responsible for the provision of a dvanced e-infrastructure services to the Greek Academic and Research Commu nity.\n\nAbout GRNET\n\nGRNET provides Internet connectivity\, high-qualit y e-Infrastructures and advanced services to the Greek Educational\, Acade mic and Research community.\n\nThrough its high-speed\, high-capacity infr astructure that spans across the entire country\, GRNET interconnects more than 150 institutions\, including all universities and technological inst itutions\, as well as many research institutes and the public Greek School Network.\n\nGRNET operates the National High Performance Computing system (a Tier-1 in the European HPC ecosystem) and offers user and application support services\, that provide Greek scientists with the computing infras tructure and expertise they need for their research enabling them to perfo rm large scale simulations.\n\nGRNET offers innovative IaaS cloud computin g services to the Greek and global research &\; education communities: “ ~okeanos” and “okeanos global” allow users to create multi-layer virtual infrastructure and instantiate virtual computing machines\, local networks to interconnect them\, and a reliable storage space within secon ds\, with few\, simple mouse clicks.\n\nGRNET aims at contributing towards Greece’s Digital Convergence with the EU\, by supporting the developmen t and encouraging the use of e-Infrastructures and services. The right and timely planning strategies\, together with the long experience and know-h ow of its people\, guarantee the continuation and enhancement of GRNET’s successful course.\n\nGreek Research and Technology Network – Networkin g Reserach and Education:\n\nwww.grnet.gr\, hpc.grnet.gr\nhttps://events.p race-ri.eu/event/794/ SUMMARY:Efficient Use of HPC Systems @GRNET URL;VALUE=URI:https://events.prace-ri.eu/event/794/ END:VEVENT END:VCALENDAR
