MPI is the dominant parallelization paradigm in high performance computing and enables one to write programs that run on distri buted memory machines\, such as the ARIS Greek supercomputer and other sys tems of the PRACE infrastructure. OpenMP is a threading based approach whi ch enables one to parallelize a program over a single shared memory machin e\, such as a single node in ARIS. The course also contains performance an d best practice considerations. The course ends with a section presenting profiling and code optimisations to understand the behavior and performanc e of parallelized codes.\n\nThe course consists of lectures and hands-on e xercises on parallel programming. Hands-on sessions (in C and Fortran) wil l allow users 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 optim izations to understand the behavior and performance of parallelized codes. \n\nAfter the course the participants should be able to write simple paral lel programs and parallelize existing programs with the basic features of MPI or OpenMP.\n\nPrerequisites\n\nThe course addresses participants who a re familiar with the C/C++ or Fortran programming languages and have worki ng experience with the Linux operating system and the use of the command l ine. Experience with parallel programming (MPI and OpenMP) is not required .\n\nBring your own laptop in order to be able to participate in the train ing hands on. 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 \nRegistration\n\nThe maximum number of participants is 25. \n\nRegistrati ons will be evaluated on a first-come\, first-served basis. GRNET is respo nsible for the selection of the participants on the basis of the training requirements and the technical skills of the candidates. GRNET will also  seek to guarantee the maximum possible geographical coverage with the part icipation of candidates from many countries.\n\nVenue\n\n \n\nARIS - Syst em Information\n\n \n\nARIS is the name of the Greek supercomputer\, depl oyed and operated by GRNET (Greek Research and Technology Network) in Athe ns. ARIS consists of 532 computational nodes seperated in four “islands ” as listed here:\n\n\n \n 426 thin nodes: Regular compute nodes w ithout accelerator.\n \n \n 44 gpu nodes: “2 x NVIDIA Tesla k40 m” accelerated nodes.\n \n \n 18 phi nodes: “2 x INTEL Xeon P hi 7120p” accelerated nodes.\n \n \n 44 fat nodes: Fat compute nodes have larger 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 lo gin nodes. \n\nAbout Tutors\n\nDr. Dellis (Male) holds a B.Sc. in Chemistr y (1990) and PhD in Computational Chemistry (1995) from the National and K apodistrian University of Athens\, Greece. He has extensive HPC and grid c omputing experience. He was using HPC systems in computational chemistry r esearch projects on fz-juelich machines (2003-2005). He received an HPC-Eu ropa grant on BSC (2009). In EGEE/EGI projects he acted as application sup port and VO software manager for SEE VO\, grid sites administrator (HG-02\ , GR-06)\, NGI_GRNET support staff (2008-2014). In PRACE 1IP/2IP/3IP/4IP/5 IP he was involved in benchmarking tasks either as group member or as BCO (2010-2017). Currently he holds the position of “Senior HPC Applications Support Engineer” at GRNET S.A. where he is responsible for activities related to user consultations\, porting\, optimization and running HPC app lications at national and international resources.\n\nDr. Ioannis E. Venet is received his PhD in 2006 from the Computer Engineering and Informatics Department at the University of Patras\, Greece. Currently he teaches "Par allel Processing" and "Software and Programming for High Performance Syste ms" at the same Department. He has participated in numerous research proje cts in the area of Parallel Computing. His main research interests include parallel programming models\, run-time systems for supporting such models \, co-processor programming (especially using GPUs and the Intel Xeon Phi) and parallelization of computationally demanding applications. \n\nAbout GRNET\n\nGRNET provides Internet connectivity\, high-quality e-Infrastruct ures and advanced services to the Greek Educational\, Academic and Researc h community.\n\nThrough its high-speed\, high-capacity infrastructure that spans across the entire country\, GRNET interconnects more than 150 insti tutions\, including all universities and technological institutions\, as w ell as many research institutes and the public Greek School Network.\n\nGR NET operates the National High Performance Computing system (a Tier-1 in t he European HPC ecosystem) and offers user and application support service s\, that provide Greek scientists with the computing infrastructure and ex pertise they need for their research enabling them to perform large scale simulations.\n\nGRNET offers innovative IaaS cloud computing services to t he Greek 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. The right and timely planning str ategies\, together with the long experience and know-how of its people\, g uarantee the continuation and enhancement of GRNET’s successful course.\ n\nGreek Research and Technology Network – Networking Reserach and Educa tion:\n\nwww.grnet.gr\, hpc.grnet.gr\n\nhttps://events.grnet.gr/event/63/ LOCATION:Central Library NTUA\, Zografou Campus Multimedia Room\, https:// goo.gl/maps/8Piu1ftakh72 URL:https://events.grnet.gr/event/63/ END:VEVENT END:VCALENDAR
