MPI is the dominant parallelization paradigm in h igh performance computing and enables one to write programs that run on di stributed memory machines\, such as the ARIS Greek supercomputer and other systems of the PRACE infrastructure. OpenMP is a threading based approach which enables one to parallelize a program over a single shared memory ma chine\, such as a single node in ARIS. The course also contains performanc e and best practice considerations\, e.g.\, hybrid MPI+OpenMP parallelisat ion. The course ends with a section presenting profiling and code optimisa tions 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 users to imme diately test and understand the taught constructs of the Message Passing  Interface (MPI) and the shared memory directives of OpenMP. The course e nds with a section presenting profiling and code optimizations to understa nd the behavior and performance of parallelized codes.\n\nAfter the course the participants should be able to write simple parallel programs and par allelize existing programs with the basic features of MPI and/or OpenMP. U sers should also be able to perform basic profiling and debugging of paral lel applications. .\n\nPrerequisites\n\nThe course addresses participants who are familiar with the C/C++ or Fortran programming languages and have working experience with the Linux operating system and the use of the comm and line. Experience with parallel programming (MPI and OpenMP) is not req uired.\n\nBring your own laptop in order to be able to participate in the training hands on. Hands on work will be done in pairs so if you don’t h ave a laptop you might work with a colleague. \n\nCourse language is Engli sh.\n\nRegistration\n\nThe maximum number of participants is 25. \n\nRegis trations will be evaluated on a first-come\, first-served basis. GRNET is responsible for the selection of the participants on the basis of the trai ning requirements and the technical skills of the candidates. GRNET will a lso seek to guarantee the maximum possible geographical coverage with the participation of candidates from many countries.\n\nVenue\n\nGRNET headqu arters\n\nAddress: 2nd  Floor\, 7\, Kifisias Av. GR 115 23 Athens\n\nInfo rmation on how to reach GRNET headquarters ia available on GRNET website: https://grnet.gr/en/contact-us/  \n\nAccommodation options near GRNET ca n be found at: https://grnet.gr/wp-content/uploads/sites/13/2015/11/Hotels -near-GRNET-en.pdf\n\nARIS - System Information\n\nARIS is the name of the Greek supercomputer\, deployed and operated by GRNET (Greek Research and Technology Network) in Athens. ARIS consists of 532 computational nodes se perated in four “islands” as listed here:\n\n\n 426 thin nodes: Regula r compute nodes without accelerator.\n \n \n 44 gpu nodes: “2 x NVIDIA T esla k40m” accelerated nodes.\n \n \n 18 phi nodes: “2 x INTEL Xeon Ph i 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 \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\nAb out Tutors\n\nDr. Dellis (Male) holds a B.Sc. in Chemistry (1990) and PhD in Computational Chemistry (1995) from the National and Kapodistrian Unive rsity of Athens\, Greece. He has extensive HPC and grid computing experien ce. He was using HPC systems in computational chemistry research projects on fz-juelich machines (2003-2005). He received an HPC-Europa grant on BSC (2009). In EGEE/EGI projects he acted as application support and VO softw are manager for SEE VO\, grid sites administrator (HG-02\, GR-06)\, NGI_GR NET support staff (2008-2014). In PRACE 1IP/2IP/3IP/4IP/5IP he was involve d in benchmarking tasks either as group member or as BCO (2010-2017). Curr ently he holds the position of “Senior HPC Applications Support Engineer ” at GRNET S.A. where he is responsible for activities related to user c onsultations\, porting\, optimization and running HPC applications at nati onal and international resources.\n\nDr. Ioannis E. Venetis received his P hD in 2006 from the Computer Engineering and Informatics Department at the University of Patras\, Greece. Currently he teaches "Parallel Processing" and "Software and Programming for High Performance Systems" at the same D epartment. He has participated in numerous research projects in the area o f Parallel Computing. His main research interests include parallel program ming models\, run-time systems for supporting such models\, co-processor p rogramming (especially using GPUs and the Intel Xeon Phi) and parallelizat ion of computationally demanding applications. \n\nMr. Nikolaos Nikoloutsa kos holds a diploma of Engineering in Computer Engineering and Informatics (2014) from the University of Patras\, Greece. From 2015 he works as soft ware engineer at GRNET S.A. where he is part of the user application suppo rt team for the ARIS HPC system. He has been involved in major national an d European projects\, such as PRACE and EUDAT. His main research interests include parallel programming models\, co-processor programming 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 Te chnical University of Athens\, Greece. His interests mainly focus on the f ields of Large Scale Computing &\; Storage Systems\, System Software fo r Scalable High Speed Interconnects for Computer Clusters and Advanced Mic roprocessor Architectures. He has published several scientific papers in i nternational journals and conference proceedings. He has received the IEEE IPDPS 2001 best paper award for the paper "Minimizing Completion Time for Loop Tiling with Computation and Communication Overlapping".
