  • Scalable Parallel Computations with PETSc @ CSC

    2 - 3 May 2019

    Scalable Parallel Computations with PETSc @ CSC https://tess.elixir-europe.org/events/scalable-parallel-computations-with-petsc-csc Description The Portable Extensible Toolkit for Scientific computing (PETSc) is a software framework for scalable numerical solution of complex problems in science and engineering. It is designed primarily for typical computations connected with Partial Differential Equations (PDE) solution, but is already successfully used also e.g., in data science. PETSc provides implementations of distributed sparse/dense/unassembled matrices, linear algebra, linear/non-linear system solvers, time integrators, mathematical optimization, discretization and more. It can as well be selectively extended with user's own implementations at any level. Codes using PETSc can be compiled on a wide range of computer architectures from iPhone to a large cluster with no code changes. PETSc is written in C but can be employed e.g., in C++, Fortran and Python programs as well. The course will interleave theory and practice — presentations and hands-on exercises with individual consultations. Learning outcome After the course participants are able to:  make use of the vast functionality available in PETSc to write their own programs, from mini-apps to bigger projects;  write their PETSc-based programs in a way allowing experiments with command-line options with no need for recompiling — for example, to apply different preconditioners to the same problem and compare their performance;  add their own functionality if needed by extending prefabricated building blocks available in PETSc; take advantage of the debugging and profiling tools within PETSc; use PETSc as a "package manager" to fetch, compile and link various external libraries such as ParMETIS easily;  do something more with PETSc, also based on their individual preferences. Prerequisites Participants need some experience in C programming, but expertise is not required. One should be familiar with:  C syntax; Control flow (if/else, loops, writing/calling functions);  Writing and calling functions; Compiling a C program on their target platform.  One also needs some conceptual knowledge of MPI:  What is message passing about; What are MPI communicators.

  • Efficient Parallel I/O @ EPCC at Imperial College London

    28 - 29 March 2019

    Efficient Parallel I/O @ EPCC at Imperial College London https://tess.elixir-europe.org/events/efficient-parallel-i-o-epcc-at-imperial-college-london Please note:  This course will take place at Imperial College London SALC 10,  Sherfield building, level 5, South Kensington Campus One of the greatest challenges to running parallel applications on large numbers of processors is how to handle file IO. Standard IO routines are not designed with parallelism in mind, and IO overheads can grow to dominate the overall runtime. Parallel file systems are optimised for large data transfers, but performance can be far from optimal if every process opens its own file or if all IO is funneled through a single master process. This hands-on course explores a range of issues related to parallel IO. It uses ARCHER and its parallel Lustre file system as a platform for the exercises; however, almost all the IO concepts and performance considerations are applicable to any parallel system. The IO part of the MPI standard gives programmers access to efficient parallel IO in a portable fashion. However, there are a large number of different routines available and some can be difficult to use in practice. Despite its apparent complexity, MPI-IO adopts a very straightforward high-level model. If used correctly, almost all the complexities of aggregating data from multiple processes can be dealt with automatically by the library. The first day of the course will cover the MPI-IO standard, developing IO routines for a regular domain decomposition example. It will also briefly cover higher-level standards such as HDF5 and NetCDF which are built on top of MPI-IO. The second day will concentrate on performance, covering how to configure the parallel file system and tune the MPI-IO library for best performance. Case studies from real codes will be presented. Prerequisites: The course assumes a good understanding of basic MPI programming in Fortran, C or C++. Knowledge of MPI derived datatypes would be useful but not essential.

  • Interactive High-Performance Computing @ JSC

    9 - 10 April 2019

    Interactive High-Performance Computing @ JSC https://tess.elixir-europe.org/events/interactive-high-performance-computing-jsc Interactive exploration and analysis of large amounts of data from scientific simulations, in-situ visualization and application control are convincing scenarios for explorative sciences. Based on the open source software Jupyter or JupyterLab, a way has been available for some time now that combines interactive with reproducible computing while at the same time meeting the challenges of support for the wide range of different software workflows. Even on supercomputers, the method enables the creation of documents that combine live code with narrative text, mathematical equations, visualizations, interactive controls, and other extensive output. However, a number of challenges must be mastered in order to make existing workflows ready for interactive high-performance computing. With so many possibilities, it's easy to lose sight of the big picture. This course provides a detailed introduction to interactive high-performance computing. The following topics are covered: Opportunities and challenges of interactive HPC Functionality and interaction of the necessary components Introduction to the most important libraries Coupling and control of simulations Visualizing results interactively   Prerequisites: Experience in Python Application Registrations are only considered until 15 March 2018 due to available space, the maximal number of participants is limited.

  • Modern C++ for Computational Scientists @ EPCC at Cambridge

    16 - 17 April 2019

    Modern C++ for Computational Scientists @ EPCC at Cambridge https://tess.elixir-europe.org/events/modern-c-for-computational-scientists-epcc-at-cambridge Since the 2011 revision to the C++ language and standard library, the ways it is now being used are quite different. Used well, these features enable the programmer to write elegant, reusable and portable code that runs efficiently on a variety of architectures. However it is still a very large and complex tool. This course will cover a minimal set of features to allow an experienced non-C++ programmer to get to grips with language. These include: overloading, templates, containers, iterators, lambdas and standard algorithms. It concludes with a brief discussion of modern frameworks for portable parallel performance which are commonly implemented in C++. The course would appeal to existing C++ programmers wanting to learn techniques that are applicable to numerical computing, or C programmers who want to know what parts of the C++ standard they should prioritise when learning new features. https://events.prace-ri.eu/event/853/ 2019-04-16 08:00:00 UTC 2019-04-17 16:30:00 UTC [] [] [] workshops_and_courses [] []

  • Message-passing Programming with MPI @ EPCC

    17 - 19 July 2019

    Message-passing Programming with MPI @ EPCC https://tess.elixir-europe.org/events/message-passing-programming-with-mpi-epcc-006600da-45d1-4a1c-a1ef-455bc049d591 The world’s largest supercomputers are used almost exclusively to run applications which are parallelised using Message Passing. The course covers all the basic knowledge required to write parallel programs using this programming model, and is directly applicable to almost every parallel computer architecture. Parallel programming by definition involves co-operation between processes to solve a common task. The programmer has to define the tasks that will be executed by the processors, and also how these tasks are to synchronise and exchange data with one another. In the message-passing model the tasks are separate processes that communicate and synchronise by explicitly sending each other messages. All these parallel operations are performed via calls to some message-passing interface that is entirely responsible for interfacing with the physical communication network linking the actual processors together. This course uses the de facto standard for message passing, the Message Passing Interface (MPI). It covers point-to-point communication, non-blocking operations, derived datatypes, virtual topologies, collective communication and general design issues. The course is normally delivered in an intensive three-day format using EPCC’s dedicated training facilities. It is taught using a variety of methods including formal lectures, practical exercises, programming examples and informal tutorial discussions. This enables lecture material to be supported by the tutored practical sessions in order to reinforce the key concepts. If you are not already familiar with basic Linux commands,logging on to a remote machine using ssh and compiling and running a program on a remote machine then we would strongly encourage you to also attend the Hands-on Introduction to HPC course running immediately prior to this course. This course is free to all academics.  Intended Learning Outcomes On completion of this course students should be able to: Understand the message-passing model in detail. Implement standard message-passing algorithms in MPI. Debug simple MPI codes. Measure and comment on the performance of MPI codes. Design and implement efficient parallel programs to solve regular-grid problems. Pre-requisite Programming Languages: Fortran, C or C++. It is not possible to do the exercises in Java. Pre-requisite setup Attendees should bring their own laptop (Windows/Mac/Linux) and will need the required software installed:   Timetable Day 1 09:30  Message-Passing Concepts 10:15  Practical: Parallel Traffic Modelling 11:00  Break 11:30  MPI Programs 12:00  MPI on ARCHER 12:15  Practical: Hello World 13:00  Lunch 14:00  Point-to-Point Communication 14:30  Practical: Pi 15:30  Break 16:00  Communicators, Tags and Modes 16:45 Practical: Ping-Pong 17:30  Finish Day 2 09:30  Non-Blocking Communication 10:00  Practical: Message Round a Ring 11:00  Break 11:30  Collective Communicaton 12:00  Practical: Collective Communication 13:00  Lunch 14:00  Virtual Topologies 14:30  Practical: Message Round a Ring (cont.) 15:30  Break 16:00  Derived Data Types 16:45  Practical: Message Round a Ring (cont.) 17:30  Finish Day 3 09:30  Introduction to the Case Study 10:00  Practical: Case Study 11:00  Break 11:30  Practical: Case Study (cont.) 13:00  Lunch 14:00  Designing MPI Programs 15:00 Individual Consultancy Session 15:30  Finish Lunch and refreshments will NOT be provided but there are places locally where these can be purchased.

    Data, lights, camera, action! Scientific visualization done beautifully using Blender @SURFsara https://tess.elixir-europe.org/events/data-lights-camera-action-scientific-visualization-done-beautifully-surfsara-66cf8248-fbcd-4fe4-8d54-4b3ce75f0e12 Would you like to make 3D visualisations that are visually more attractive than what ParaView or VisIt can provide? Do you need an image for a grant application that needs to look spectacular? Would you like to create a cool animation of flying through your simulation data? Then this course may be for you! The goal of this course is to provide you with hands-on knowledge of producing great images and animations from 3D (scientific) data. We will be using the open-source package Blender (http://www.blender.org), which provides good basic functionality, while also being usable for advanced usage and general editing of 3D data. It is also a lot of fun to work with (once you get used to its graphical interface). Example types of relevant scientific data are 3D cell-based simulations, 3D models from photogrammetry, (isosurfaces of) 3D medical scans, molecular models and earth sciences data. Note that we don't focus on information visualization of abstract data, such as graphs (although you could convert those into a 3D model first and then use them in Blender). We like to encourage participants to bring along (a sample) of the data they normally work with and would like to apply the course knowledge to. https://events.prace-ri.eu/event/866/ 2019-05-21 07:00:00 UTC 2019-05-21 15:30:00 UTC [] [] [] workshops_and_courses [] []

    OpenMP GPU Directives for Parallel Accelerated Supercomputers - an alternative to CUDA from Cray perspective @ HLRS https://tess.elixir-europe.org/events/openmp-gpu-directives-for-parallel-accelerated-supercomputers-an-alternative-to-cuda-from-cray-perspective-hlrs-f423be53-abbd-4597-922f-d472b88dd6d2 Overview This workshop will cover the directive-based programming model based on OpenMP v4 whose multi-vendor support allows users to portably develop applications for parallel accelerated supercomputers. It also includes comparison to the predecessor interface OpenACC v2. The workshop will also demonstrate how to use the Cray Programming Environment tools to identify application bottlenecks, facilitate the porting, provide accelerated performance feedback and to tune the ported applications. The Cray scientific libraries for accelerators will be presented, and interoperability of the directives approach with these and with CUDA will be demonstrated. Through application case studies and tutorials, users will gain direct experience of using both OpenMP and OpenACC directives in realistic applications. Users may also bring their own codes to discuss with Cray specialists or begin porting. This course provides scientific training in Computational Science, and in addition, the scientific exchange of the participants among themselves.

  • Performance portability for GPU application using high-level programming approaches @ MdlS /Idris

    1 - 2 April 2019

    Performance portability for GPU application using high-level programming approaches @ MdlS /Idris https://tess.elixir-europe.org/events/performance-portability-for-gpu-application-using-high-level-programming-approaches-mdls-idris-e05a2681-bd72-4aea-9ea1-7fa210925446 When developing a numerical simulation code with high performance and efficiency in mind, one is often compelled to accept a trade-off between using a native-hardware programming model (like CUDA or OpenCL), which has become tremendously challenging, and loosing some cross-platform portability. Porting a large existing legacy code to a modern HPC platform, and developing a new simulation code, are two different tasks that may be benefit from a high-level programming model, which abstracts the low-level hardware details. This training presents existing high-level programming solutions that can preserve at best as possible performance, maintainability and portability across the vast diversity of modern hardware architectures (multicore CPU, manycore, GPU, ARM, ..) and software development productivity. We will  provide an introduction to the high-level C++ programming model Kokkos https://github.com/kokkos, and show basic code examples  to illustrate the following concepts through hands-on sessions: hardware portability: design an algorithm once and let the Kokkos back-end (OpenMP, CUDA, ...) actually derive an efficient low-level implementation; efficient architecture-aware memory containers: what is a Kokkos::view; revisit fundamental parallel patterns with Kokkos: parallel for, reduce, scan, ... ; explore some mini-applications. Several detailed examples in C/C++/Fortran will be used in hands-on session on the high-end hardware platform Ouessant (http://www.idris.fr/ouessant/), equipped with Nvidia Pascal GPUs. Prerequisites: Some basic knowledge of the CUDA programming model and of C++. https://events.prace-ri.eu/event/818/ 2019-04-01 07:30:00 UTC 2019-04-02 15:00:00 UTC [] [] [] workshops_and_courses [] []

  • Concepts of GASPI and interoperability with other communication APIs @ HLRS

    1 - 2 July 2019

    Concepts of GASPI and interoperability with other communication APIs @ HLRS https://tess.elixir-europe.org/events/concepts-of-gaspi-and-interoperability-with-other-communication-apis-hlrs Overview In this tutorial we present an asynchronous data flow programming model for Partitioned Global Address Spaces (PGAS) as an alternative to the programming model of MPI. GASPI, which stands for Global Address Space Programming Interface, is a partitioned global address space (PGAS) API. The GASPI API is designed as a C/C++/Fortran library and focused on three key objectives: scalability, flexibility and fault tolerance. In order to achieve its much improved scaling behaviour GASPI aims at asynchronous dataflow with remote completion, rather than bulk-synchronous message exchanges. GASPI follows a single/multiple program multiple data (SPMD/MPMD) approach and offers a small, yet powerful API (see also http://www.gaspi.de and http://www.gpi-site.com). GASPI is successfully used in academic and industrial simulation applications. Hands-on sessions (in C and Fortran) will allow users to immediately test and understand the basic constructs of GASPI. This course provides scientific training in Computational Science, and in addition, the scientific exchange of the participants among themselves.

  • Node-Level Performance Engineering @ HLRS

    27 - 28 June 2019

    Node-Level Performance Engineering @ HLRS https://tess.elixir-europe.org/events/node-level-performance-engineering-hlrs-9fa9fd8a-10c4-41bc-afab-5697ace21b4d Overview This course teaches performance engineering approaches on the compute node level. "Performance engineering" as we define it is more than employing tools to identify hotspots and bottlenecks. It is about developing a thorough understanding of the interactions between software and hardware. This process must start at the core, socket, and node level, where the code gets executed that does the actual computational work. Once the architectural requirements of a code are understood and correlated with performance measurements, the potential benefit of optimizations can often be predicted. We introduce a "holistic" node-level performance engineering strategy, apply it to different algorithms from computational science, and also show how an awareness of the performance features of an application may lead to notable reductions in power consumption.This course provides scientific training in Computational Science, and in addition, the scientific exchange of the participants among themselves.
