  • 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. Applicants will be notified, whether they are accepted for participitation.

  • Uncertainty quantification @MdlS

    27 - 29 May 2019

    Uncertainty quantification @MdlS https://tess.elixir-europe.org/events/uncertainty-quantification-mdls-8ab27eae-4c4e-457e-bc99-0ccf6ee93b78 Uncertainty in computer simulations, deterministic and probabilistic methods for quantifying uncertainty, OpenTurns software, Uranie software Content Uncertainty quantification takes into account the fact that most inputs to a simulation code are only known imperfectly. It seeks to translate this uncertainty of the data to improve the results of the simulation. This training will introduce the main methods and techniques by which this uncertainty propagation can be handled without resorting to an exhaustive exploration of the data space. HPC plays an important role in the subject, as it provides the computing power made necessary by the large number of simulations needed. The course will present the most important theoretical tools for probability and statistical analysis, and will illustrate the concepts using the OpenTurns software. Course Outline Day 1 - General methodology for handling uncertainty, presentation of a case study - Fundamental notions from probability and statistics - General introduction to the software tools: OpenTurns and Uranie   Day 2 - Statistical estimation: parametric and non-parametric, testing - Modeling with non-numerical data: expert judgement, entropy - Central trend: local and gloal sensitivity indices (design of experiments, sampling, Sobol indices) - computing the probability of rare events, simulation methods, FORM/SORM   Day 3 - Distributed computing: parallel solvers, batch jobs submission on a parallel computer, implementation within OpenTurns / Salome and Uranie - Introduction to meta-model building, least-squares, other response surface, Kriging, neural networks - Introduction to polynomial chaos Learning outcomes Learn to recognize when uncertainty quantification can bring new insight to simulations. Know the main tools and techniques to investigate uncertainty propagation. Gain familiarity with modern tools for actually carrying out the computations in a HPC context. Prerequisites Basic knowledge of probability will be useful, as will a basic familiarity with Linux. https://events.prace-ri.eu/event/815/ 2019-05-27 07:30:00 UTC 2019-05-29 15:00:00 UTC [] [] [] workshops_and_courses [] []

    Spring School in Computational Chemistry 2019 @ CSC https://tess.elixir-europe.org/events/spring-school-in-computational-chemistry-2019-csc Description The Spring School provides a comprehensive, tutorial-style, hands-on, introductory and intermediate-level treatment to the essential ingredients for molecular modeling and computational chemistry using modern supercomputers. The School program is being prepared, but the main content will be similar to last years and consists of: Classical molecular dynamics, intro + hands on (1 day) Electronic structure theory, intro  + hands on (1 day) Machine learning in chemistry, intro + hands on Special topics: e.g. on Visualization, Enchanced Sampling Techniques, etc. The school is a must for graduate students in the field, providing an overview on "what can be calculated and how should it be done", without forgetting the important aspect of network building. Note: the School has been overbooked in one week after registration was opened. We are investigating the possibility to accommodate more participants, but it is likely that new registrations will go to waiting list. Learning outcome The learning outcome is to gain an overview of the two main methods in computational chemistry — molecular dynamics and electronic structure calculations — in connection with related HPC software packages and other useful skills in the trade. The workshop is also suited for an intensive crash course (the first two days) in computational modelling and is expected to be useful for students and researchers also in physics, materials sciences and biosciences. The following "Special topics" then build on this foundation. Prerequisites Working knowledge and some work experience from some branch of computational chemistry will be useful. Basic linux skills for hands-on exercises and elementary Python for Machine Learning hands-on. More detailed description of pre-requisites and links for self study.

  • Introduction to Hybrid Programming in HPC @ LRZ

    28 - 29 January 2019

    Introduction to Hybrid Programming in HPC @ LRZ https://tess.elixir-europe.org/events/introduction-to-hybrid-programming-in-hpc-lrz-112b005c-321c-495b-be52-91b7f62fe4a4 Overview Most HPC systems are clusters of shared memory nodes. Such SMP nodes can be small multi-core CPUs up to large many-core CPUs. Parallel 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 both 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. The course is a PRACE Advanced Training Center event. It is organized by LRZ in cooperation with HLRS, RRZE, and VSC (Vienna Scientific Cluster).

  • 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 [] []

  • Parallel and Scalable Machine Learning @ JSC

    25 - 27 February 2019

    Parallel and Scalable Machine Learning @ JSC https://tess.elixir-europe.org/events/parallel-and-scalable-machine-learning-jsc-424a6e5f-64a6-471e-af99-5b940b60a8a4 The course offers basics of analyzing data with machine learning and data mining algorithms in order to understand foundations of learning from large quantities of data. This course is especially oriented towards beginners that have no previous knowledge of machine learning techniques. The course consists of general methods for data analysis in order to understand clustering, classification, and regression. This includes a thorough discussion of test datasets, training datasets, and validation datasets required to learn from data with a high accuracy. Easy application examples will foster the theoretical course elements that also will illustrate problems like overfitting followed by mechanisms such as validation and regularization that prevent such problems. The tutorial will start from a very simple application example in order to teach foundations like the role of features in data, linear separability, or decision boundaries for machine learning models. In particular this course will point to key challenges in analyzing large quantities of data sets (aka ‘big data’) in order to motivate the use of parallel and scalable machine learning algorithms that will be used in the course. The course targets specific challenges in analyzing large quantities of datasets that cannot be analyzed with traditional serial methods provided by tools such as R, SAS, or Matlab. This includes several challenges as part of the machine learning algorithms, the distribution of data, or the process of performing validation. The course will introduce selected solutions to overcome these challenges using parallel and scalable computing techniques based on the Message Passing Interface (MPI) and OpenMP that run on massively parallel High Performance Computing (HPC) platforms. The course ends with a more recent machine learning method known as deep learning that emerged as a promising disruptive approach, allowing knowledge discovery from large datasets in an unprecedented effectiveness and efficiency. Prerequisites: Knowledge on job submissions to large HPC machines using batch scripts, knowledge of mathematical basics in linear algebra helpful. Participants should bring their own notebooks (with an ssh-client). Learning outcome: After this course participants will have a general understanding how to approach data analysis problems in a systematic way. In particular this course will provide insights into key benefits of parallelization such as during the n-fold cross-validation process where significant speed-ups can be obtained compared to serial methods. Participants will also get a detailed understanding why and how parallelization provides benefits to a scalable data analyzing process using machine learning methods for big data and a general understanding for which problems deep learning algorithms are useful and how parallel and scalable computing is facilitating the learning process when facing big datasets. Participants will learn that deep learning can actually perform ‘feature learning’ that bears the potential to significantly speed-up data analysis processes that previously required much feature engineering. Application Applicants will be notified one month before the course starts, whether they are accepted for participitation.

  • 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.

  • 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 @ LRZ https://tess.elixir-europe.org/events/node-level-performance-engineering-lrz-9d1ccd4c-855b-4ad3-b4a1-44a0054656c5 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. The course is a PRACE training event. Introduction Our approach to performance engineering Basic architecture of multicore systems: threads, cores, caches, sockets, memory The important role of system topology Tools: topology & affinity in multicore environments Overview likwid-topology and likwid-pin Microbenchmarking for architectural exploration Properties of data paths in the memory hierarchy Bottlenecks OpenMP barrier overhead Roofline model: basics Model assumptions and construction Simple examples Limitations of the Roofline model Pattern-based performance engineering Optimal use of parallel resources Single Instruction Multiple Data (SIMD) Cache-coherent Non-Uniform Memory Architecture (ccNUMA) Simultaneous Multi-Threading (SMT) Tools: hardware performance counters Why hardware performance counters? likwid-perfctr Validating performance models Roofline case studies Dense matrix-vector multiplication Sparse matrix-vector multiplication Jacobi (stencil) smoother Optional: The ECM performance model https://events.prace-ri.eu/event/821/ 2019-02-20 08:00:00 UTC 2019-02-21 16:00:00 UTC [] [] [] workshops_and_courses [] []

    Energy Efficency in HPC @Cineca https://tess.elixir-europe.org/events/energy-efficency-in-hpc-cineca Description: With the steaming out of Moore's law and the end of Dennard's scaling the pace dictated on the performance increase of High Performance Computing Systems among generations has led to power constrained architectures and systems. In addition power consumption represents a significant cost factor in the overall HPC system economy. For this reasons in the recent years researchers, supercomputing centers and major vendors have developed new tools and methodologies to measure and optimize the energy consumption of large scale high performance system installation. Due to the link between energy consumption, power consumption and execution time of the application executed by the final user it is important for these tools and methodology to consider all these aspects empowering the final user and the system administrator with the capability of finding the best configuration given different high level objectives.  The school will give an introductory course on the fundamental concept of power consumption and energy efficiency in HPC systems. Then it will focuses on the mechanisms that today computing elements and systems provide in terms of monitoring and control the power and energy dissipation. Finally it will introduce and give hand ons on a set of tools for reducing the energy consumption in HPC devices.  The school is organized in four main sessions driving the audience from the physical and engineering principles underlying power consumption in supercomputing systems to the practical usage of state-of-the-art tools for monitoring and controlling the energy efficiency of supercomputing machines and workloads. The tools that will be covered are the MSR-SAFE (LLNL), MERIC (IT4I), COUNTDOWN (UNIBO), GEOPM (Intel) libraries.  Skills: By the end of the course, participants will be expected to: have a good understanding of the principles underlying the power consumption, energy dissipation in high performance computing nodes recognize trade-offs and implications of changing the power consumption in scientific computing systems during the execution of scientific computing applications have a clear view on the state-of-the-art and of practice in controlling the power consumption and energy efficiency of supercomputing nodes and processors. learn the internals and the usage of a set of user-space run-time libraries for controlling/optimizing the power consumption and energy efficiency in x86 computing nodes while executing user's applications. learn how to use these tools for optimize the energy consumption of your codes. Target Audience: Researchers, student, system administrator, application developers who may wish to limit the environmental impact of their computations, as well as reducing the cost of energy provisioning in supercomputing system - promoting a more sustainable supercomputing ecosystem.

  • High-performance scientific computing in C++ @ JSC

    27 - 29 May 2019

    High-performance scientific computing in C++ @ JSC https://tess.elixir-europe.org/events/high-performance-scientific-computing-in-c-jsc-ee5bae79-ed57-4de5-bfad-0ca030797e59 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 on contemporary computer hardware, with many levels of parallelism, requires understanding C++ code from a more 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, who are already familiar with C++14, and wish to develop maintainable and fast applications. They will learn to identify and avoid performance degrading characteristics, such as unnecessary memory operations, branch mispredictions, and unintentionally strong ordering assumptions. Two powerful open source libraries to help write structured parallel applications will also be introduced: Intel (R) Threading Building Blocks NVIDIA 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 1May 2019 due to available space, the maximal number of participants is limited. Applicants will be notified, whether they are accepted for participitation. Instructor: Dr. Sandipan Mohanty, JSC Contact For any questions concerning the course please send an e-mail to s.mohanty@fz-juelich.de https://events.prace-ri.eu/event/824/ 2019-05-27 07:00:00 UTC 2019-05-29 14:30:00 UTC [] [] [] workshops_and_courses [] []
  • High Performance Parallel IO and post-processing @ MdlS

    11 - 13 March 2019

    High Performance Parallel IO and post-processing @ MdlS https://tess.elixir-europe.org/events/high-performance-parallel-io-and-post-processing-mdls The increase in computational power goes hand in hand with an increase in the size of the data to be managed, both on the input and on the output sides. IO can easily become a bottleneck for large scale architectures. Understanding of parallel file system mechanisms and parallel IO concepts enables users to efficiently use existing high level libraries like HDF5. With the increasing performance gap between compute and storage, even the best use of IO bandwidth might not be enough and data reduction based on in-situ or in-transit post-processing becomes a requirement for large-scale codes. More and more libraries able to handle this become available. This course proposes an introduction to FlowVR, a technology developed at Inria dedicated to in-situ and in-transit post-processing. To handle the multiplication of libraries, this course will also introduce the Parallel Data Interface (PDI), a solution to couple simulation codes with libraries for I/O and post-processing based on simple annotations. PDI improves code quality with a) annotations independent of the library used, b) a choice of IO strategy at runtime in YAML and c) negligible overhead to access the full power of the underlying libraries. Agenda: Day 1: HDF5, pHDF5 and general parallel IO concepts (2x3h, including hands-on) Day 2: Lustre file system (1h30) Day 2: FlowVR (1h30 + 3h including hands-on) Day 3: Parallel Data Interface (3h including hands-on) Day 3: Diving deeper into HDF5, FlowVR or PDI, your choice ! (3h) Instructors: M. Haefele (Maison de la Simulation, CNRS), Thomas Leibovici (TGCC, CEA), Bruno Raffin (INRIA), Julien Bigot (Maison de la Simulation, CEA) Learning outcomes: After this course, participants should understand the trade-offs implied by using a parallel file-system, and know how to efficiently use parallel IO libraries. Participants will also have a basic understanding and practise of FlowVR and PDI. Prerequisites: Knowledge of C or Fortran programming languages, parallel programming with MPI   https://events.prace-ri.eu/event/814/ 2019-03-11 08:30:00 UTC 2019-03-13 16:00:00 UTC [] [] [] workshops_and_courses [] []
