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 \n 426 thin nodes: Reg ular compute nodes without accelerator.\n \n \n 44 gpu nodes: “2 x NVIDI A Tesla k40m” accelerated nodes.\n \n \n 18 phi nodes: “2 x INTEL Xeon Phi 7120p” accelerated nodes.\n \n \n 44 fat nodes: Fat compute nodes h ave larger number of cores and memory per core than a thin node.\n \n\n\nA ll the nodes are connected via Infiniband network and share 2PB GPFS stora ge.The infrastructure also has an IBM TS3500 library of maximum storage ca pacity of about 6 PB. Access to the system is provided by two login nodes. \n\nAbout Tutors\n\nDr. Dellis (Male) holds a B.Sc. in Chemistry (1990) a nd PhD in Computational Chemistry (1995) from the National and Kapodistria n University of Athens\, Greece.
