MPI is the dominant parallelization par adigm in high performance computing and enables one to write programs that run on distributed memory machines\, such as the ARIS Greek supercomputer and other systems of the PRACE infrastructure. OpenMP is a threading base d approach which enables one to parallelize a program over a single shared memory machine\, such as a single node in ARIS. The course also contains performance and best practice considerations\, e.g.\, hybrid MPI+OpenMP pa rallelisation. The course ends with a section presenting profiling and cod e optimisations to understand the behavior and performance of parallelized codes.\n\nThe 3 day course consists of lectures and hands-on exercises on parallel programming. Hands-on sessions (in C and Fortran) will allow use rs to immediately test and understand the taught constructs of the Message Passing  Interface (MPI) and the shared memory directives of OpenMP. The course ends with a section presenting profiling and code optimizations to understand the behavior and performance of parallelized codes.\n\nAfter t he course the participants should be able to write simple parallel program s and parallelize existing programs with the basic features of MPI or Open MP.\n\nPrerequisites\n\nThe course addresses participants who are familiar with the C/C++ or Fortran programming languages and have working experien ce with the Linux operating system and the use of the command line. Experi ence with parallel programming (MPI and OpenMP) is not required.\n\nBring your own laptop in order to be able to participate in the training hands o n. Hands on work will be done in pairs so if you don’t have a laptop you might work with a colleague. \n\nCourse language is English.\n\nRegistrat ion\n\nThe maximum number of participants is 25. \n\nRegistrations will be evaluated on a first-come\, first-served basis. GRNET is responsible for the selection of the participants on the basis of the training requirement s and the technical skills of the candidates. GRNET will also seek to gua rantee the maximum possible geographical coverage with the participation o f candidates from many countries.\n\nVenue\n\nGRNET headquarters\n\nAddres s: 2nd  Floor\, 7\, Kifisias Av. GR 115 23 Athens\n\nInformation on how t o reach GRNET headquarters ia available on GRNET website: https://grnet.gr /en/contact-us/  \n\nAccommodation options near GRNET can be found at: h ttps://grnet.gr/wp-content/uploads/sites/13/2015/11/Hotels-near-GRNET-en.p df\n\nARIS - System Information\n\nARIS is the name of the Greek supercomp uter\, deployed and operated by GRNET (Greek Research and Technology Netwo rk) in Athens. ARIS consists of 532 computational nodes seperated in four “islands” as listed here:\n\n\n 426 thin nodes: Regular compute nodes without accelerator.\n \n \n 44 gpu nodes: “2 x NVIDIA Tesla k40m” acc elerated nodes.\n \n \n 18 phi nodes: “2 x INTEL Xeon Phi 7120p” accel erated nodes.\n \n \n 44 fat nodes: Fat compute nodes have larger number o f cores and memory per core than a thin node.\n \nAll the nodes are connec ted via Infiniband network and share 2PB GPFS storage.The infrastructure a lso has an IBM TS3500 library of maximum storage capacity of about 6 PB. A ccess to the system is provided by two login nodes. \n\nAbout Tutors\n\nDr . Dellis (Male) holds a B.Sc. in Chemistry (1990) and PhD in Computational Chemistry (1995) from the National and Kapodistrian University of Athens\ , Greece. He has extensive HPC and grid computing experience. He was using HPC systems in computational chemistry research projects on fz-juelich ma chines (2003-2005). He received an HPC-Europa grant on BSC (2009). In EGEE /EGI projects he acted as application support and VO software manager for SEE VO\, grid sites administrator (HG-02\, GR-06)\, NGI_GRNET support staf f (2008-2014). In PRACE 1IP/2IP/3IP/4IP/5IP he was involved in benchmarkin g tasks either as group member or as BCO (2010-2017). Currently he holds t he position of “Senior HPC Applications Support Engineer” at GRNET S.A . where he is responsible for activities related to user consultations\, p orting\, optimization and running HPC applications at national and interna tional resources.\n\nDr. Ioannis E. Venetis received his PhD in 2006 from the Computer Engineering and Informatics Department at the University of P atras\, Greece. Currently he teaches "Parallel Processing" and "Software a nd Programming for High Performance Systems" at the same Department. He ha s participated in numerous research projects in the area of Parallel Compu ting. His main research interests include parallel programming models\, ru n-time systems for supporting such models\, co-processor programming (espe cially using GPUs and the Intel Xeon Phi) and parallelization of computati onally demanding applications. \n\nPaschalis Korosoglou is the technical c oordinator of the Scientific Computing Office at the Aristotle University of Thessaloniki. He holds an MSc in Computational science and has particip ated in major national and European projects\, such as EGEE\, EGI\, SEE-GR ID\, EUChinaGrid\, HellasGrid\, PRACE and HellasHPC\, mainly in user servi ces provisioning and application support activities. In this respect he ho lds a solid background on scientific applications porting\, profiling\, op timisation and benchmarking activities and has developed under several occ asions code optimisation improvements related to hybrid parallel implement ations (MPI/OpenMP) and parallel I/O best practices. He has been involved in national and international Working Groups\, such as CSIRT\, EUGridPMA\, GOC\, SAM and is an active contributor within the e-Infrastructures Polic y Group (e-IRG).\n\nGeorge Z. Zachos is a student at the Department of Com puter Science &\; Engineering\, University of Ioannina. He has extensiv e experience on systems administration and systems programming. Since 2015 he is a member of the Parallel Processing Group of the same Department wh ere he works on shared and distributed memory systems and their programmin g models. Currently\, he is actively involved with the development of OMPi \, an open source OpenMP compiler and runtime system for C.\n\nAbout GRNET \n\nGRNET provides Internet connectivity\, high-quality e-Infrastructures and advanced services to the Greek Educational\, Academic and Research com munity.\n\nThrough its high-speed\, high-capacity infrastructure that span s across the entire country\, GRNET interconnects more than 150 institutio ns\, including all universities and technological institutions\, as well a s many research institutes and the public Greek School Network.\n\nGRNET o perates the National High Performance Computing system (a Tier-1 in the Eu ropean HPC ecosystem) and offers user and application support services\, t hat provide Greek scientists with the computing infrastructure and experti se they need for their research enabling them to perform large scale simul ations.\n\nGRNET offers innovative IaaS cloud computing services to the Gr eek and global research &\; education communities: “ ~okeanos” and “okeanos global” allow users to create multi-layer virtual infrastruct ure and instantiate virtual computing machines\, local networks to interco nnect them\, and a reliable storage space within seconds\, with few\, simp le mouse clicks.\n\nGRNET aims at contributing towards Greece’s Digital Convergence with the EU\, by supporting the development and encouraging th e use of e-Infrastructures and services.
