  • [ONLINE] High-performance scientific computing in C++ @ JSC

    21 - 24 June 2021

    [ONLINE] High-performance scientific computing in C++ @ JSC https://tess.elixir-europe.org/events/online-high-performance-scientific-computing-in-c-jsc Modern C++, with its support for procedural, objected oriented, generic and functional programming styles, offers many powerful abstraction mechanisms to express complexity at a high level while remaining very efficient. It is therefore the language of choice for many scientific projects. However, achieving high performance by today's standards requires understanding and exploiting multiple levels of parallelism, and understanding C++ code from a performance centric viewpoint. In this course, the participants will learn how to write C++ programs which better utilize typical HPC hardware resources of the present day. The course is geared towards scientists and engineers already familiar with C++17 (at the very least C++14), who wish to develop maintainable and fast applications. They will learn techniques to better utilize CPU caches, instruction pipelines, SIMD functionality and multi-threading. Shared memory parallel programming on multiple CPU cores will be introduced using parallel STL of C++17 and Intel (R) Threading Building Blocks. The participants will also learn basic GPGPU programming in C++ using NVidia CUDA and Thrust. Prerequisites: Good working knowledge of C++, especially the C++14 standard. Please check with these questions whether your C++ knowlegde fulfills the requirements. Application Registrations are only considered until 7 June 2021, the maximal number of participants is limited. Applicants will be notified, whether they are accepted for participitation.

  • [ONLINE] Introduction to Hybrid Programming in HPC @ VSC Vienna

    15 - 17 June 2021

    [ONLINE] Introduction to Hybrid Programming in HPC @ VSC Vienna https://tess.elixir-europe.org/events/online-introduction-to-hybrid-programming-in-hpc-vsc-vienna This course will be delivered as an ONLINE COURSE (using Zoom) for remote participation. REGISTRATION is strictly NECESSARY since the details to access the online course will be provided to the registered and accepted attendees only. Registration follows the "first come – first served" principle. For the online course we can take a maximum of 40 persons. Additional registrations will be added to a waiting list. Furthermore, accepted participants will be contacted a few days before the course and asked to do a short PRE-ASSIGNMENT that has to be completed before the course starts. The HANDS-ON LABS will be done on the Austrian flagship supercomputer VSC-4, all participants will get a training user account at VSC-4 for the duration of the course. Overview Most HPC systems are clusters of shared memory nodes. To use such systems efficiently both memory consumption and communication time has to be optimized. Therefore, hybrid programming may combine the distributed memory parallelization on the node interconnect (e.g., with MPI) with the shared memory parallelization inside of each node (e.g., with OpenMP or MPI-3.0 shared memory). This course analyzes the strengths and weaknesses of several parallel programming models on clusters of SMP nodes. Multi-socket-multi-core systems in highly parallel environments are given special consideration. MPI-3.0 has introduced a new shared memory programming interface, which can be combined with inter-node MPI communication. It can be used for direct neighbor accesses similar to OpenMP or for direct halo copies, and enables new hybrid programming models. These models are compared with various hybrid MPI+OpenMP approaches and pure MPI. Numerous case studies and micro-benchmarks demonstrate the performance-related aspects of hybrid programming. Hands-on sessions are included on all days. Tools for hybrid programming such as thread/process placement support and performance analysis are presented in a "how-to" section. This course provides scientific training in Computational Science and, in addition, the scientific exchange of the participants among themselves. Content Levels: Beginners = 0:00h (0%) + Intermediate = 1:30h (10%) + Advanced = 13:30h (90%) This course is a PRACE training event. It is organized by the VSC Research Center, TU Wien, in cooperation with HLRS and RRZE.

  • [ONLINE] Workshop on OpenMP Software Tools @ ENCCS/Intel

    1 - 2 June 2021

    [ONLINE] Workshop on OpenMP Software Tools @ ENCCS/Intel https://tess.elixir-europe.org/events/online-workshop-on-openmp-software-tools-enccs-intel Description OpenMP is a portable and scalable parallel programming model that gives programmers a flexible interface for directive-based programming of shared-memory parallel machines. Used in conjunction with MPI, OpenMP can enable scientific software to be scaled up to large supercomputers. Since version 4.0, OpenMP supports offloading to accelerator devices such as GPUs and thus provides developers with a single framework that can be used across existing and future GPU devices from multiple vendors. This workshop, split over two half days, will focus on OpenMP usage and performance tuning for both conventional threadings on CPUs as well as offloading on GPUs.  A short overview of the Intel oneAPI Toolkits will be given. Compiler options are crucial for optimal performance and thus a short introduction to optimization flags will be provided. Typical OpenMP patterns will be discussed and presented as templates for user applications. As threading errors can be hard to find, a correctness checking tool that finds real and potential threading errors will be introduced. Finally, performance bottlenecks will be discussed and methods to detect them will be introduced. Participants will be provided with exercises and instructions to run tutorials on the Intel Devcloud (https://software.intel.com/content/www/us/en/develop/tools/devcloud.html) during and after the workshop. The workshop will be followed by an online OpenMP hackathon on June 8-9 where invited teams of researchers and developers can get help from expert mentors to implement or optimise OpenMP in their own HPC software. If this sounds interesting, have a look at the event page at [LINK]! Learning objectives After attending this workshop, you will have learned:  Typical code patterns for applying OpenMP directives for parallelizing and vectorizing loops and regions How to use Intel tools effectively.  How to apply the Advisor tool for finding appropriate loops for OpenMP offloading.  How to check the correctness and finding potential threading errors.  How to perform different types of HPC and threading analysis as well as micro-architectural analysis. General tuning methodologies, common parallel bottlenecks, and how to solve them.  Prerequisites Basic understanding of parallel programming paradigms and C/C++ or Fortran programming.

  • [ONLINE] Advanced topics in scientific visualization with Blender: geometry, scripts, animation, action! @ SURF

    25 May - 8 June 2021

    [ONLINE] Advanced topics in scientific visualization with Blender: geometry, scripts, animation, action! @ SURF https://tess.elixir-europe.org/events/online-advanced-topics-in-scientific-visualization-with-blender-geometry-scripts-animation-action-surf [NOTE: this course consists of 3 online sessions spread over a period of 2 weeks. Please read the details below.] Overview This course is a follow-up to our introductory Blender course. We assume you are familiar with working with Blender and have some experience with topics such as the Blender UI, 3D meshes, materials, lighting and cameras. In this course you will learn a number of advanced Blender topics: * The basics of the Python API that is available in Blender. You will learn how the API is structured and eventually start making some simple geometry with code. This can be used, for example, for writing custom import scripts or to perform operations that you would otherwise do manually. * The node-based shader editor that is used to create and edit materials. In our introductory Blender course we did go into detail on materials, but without describing the node-based shader networks that are the basis of materials. Here, we go deeper into these node network and how to edit them. * More advanced animation topics, such as shape keys. Another important part of the course is that you will work on a visualisation based on your own research or other endeavours. Course duration The basis of the course is self-paced training during the two-week course period, using course materials that we provide. These consist of videos and exercises. During the course period you can work on the materials in your own pace. We provide a Discord communication channel with the course teachers that you can use for questions and feedback during the course. We use a small number of online plenary sessions spread over the indicated two-week period, beginning with an introductory webinar and two follow-up feedback sessions. These are used to discuss your projects and make sure you are able to make progress. Your own project and data To get the most out of the course we would like you to use a dataset from your work (or sample thereof) that you want to use for visualisation with Blender. Alternatively, we have a back-up dataset to work with, but it most likely will originate from a different scientific domain than your own. So please collect some data you think would be great to make 3D visualisations of and that you are comfortable with. During the online sessions we would like you to present your visualisation goals, your data, and your progress at making a visualisation with Blender. During the interactive moments our visualisation team will help you further with your specific project and challenges. All the contents and more detailed information More information will be available soon! https://events.prace-ri.eu/event/1192/ 2021-05-25 08:00:00 UTC 2021-06-08 15:00:00 UTC [] [] [] workshops_and_courses [] []

  • [ONLINE] OpenMP Hackathon @ENCCS/Intel

    8 - 9 June 2021

    [ONLINE] OpenMP Hackathon @ENCCS/Intel https://tess.elixir-europe.org/events/online-openmp-hackathon-enccs-intel Description OpenMP is a portable and scalable parallel programming model that gives programmers a flexible interface for directive-based programming of shared-memory parallel machines. Used in conjunction with MPI, OpenMP can enable scientific software to be scaled up to large supercomputers. Since version 4.0, OpenMP supports offloading to accelerator devices such as GPUs and thus provides developers with a single framework that can be used across existing and future GPU devices from multiple vendors. Following the OpenMP training workshop on June 1-2, ENCCS in collaboration with Intel will host an OpenMP hackathon for teams of researchers and developers who want to either: implement OpenMP in their code (for either CPUs or GPUs), or optimize their existing OpenMP implementation using state-of-the-art Intel Tools.  To apply for participation in the hackathon you will need a well-defined project with clearly stated goals, and we recommend you to join a team with at least 2 people. Invited teams will be paired up with experts from both Intel and ENCCS/SNIC who will provide hands-on mentoring and pair-programming sessions. Note that hackathon participants should also attend the training workshop on June 1-2. Teams will be able to run experiments both on the Intel Devcloud (https://software.intel.com/content/www/us/en/develop/tools/devcloud.html) and on the Tetralith cluster at NSC (https://www.nsc.liu.se/systems/tetralith/). Invited teams will receive instructions for applying for accounts on these systems. Prerequisites You should bring your own code in C, C++, or Fortran to this event.

  • [ONLINE] Efficient Parallel Programming with GASPI @ HLRS

    24 - 25 June 2021

    [ONLINE] Efficient Parallel Programming with GASPI @ HLRS https://tess.elixir-europe.org/events/online-efficient-parallel-programming-with-gaspi-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 https://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.

  • [ONLINE] Node-Level Performance Engineering @ HLRS

    12 - 15 July 2021

    [ONLINE] Node-Level Performance Engineering @ HLRS https://tess.elixir-europe.org/events/online-node-level-performance-engineering-hlrs March 17, 2021: This course was extended with an additional 4th day on performance tools, presented by ZIH, TU Dresden. 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.
