Supercomputing Frontiers Europe 2019

Schedule

All of our workshops start 14th of March at 9:30 a.m. at University of Warsaw Library, Dobra 56/66 st. Full schedule for that day.

Tutorial 1:
High Performance I/O and in situ data processing using the ADIOS framework

Presenters:
Scott A. Klasky, group leader for Scientific Data in the Computer Science and Mathematics Division, Oak Ridge National Laboratory
Norbert Podhorszki, team leader in the Scientific Data Group in the Computer Science and Mathematics Division, Oak Ridge National Laboratory
Abstract:
As concurrency and complexity continue to increase on high-end machines, I/O performance is rapidly becoming a fundamental challenge to achieving exascale computing. Wider adoption of higher-level I/O abstractions will be critically important to address this challenge. Modern I/O libraries provide data models, portable APIs, storage abstractions, and self-describing data containers. They achieve high performance and scalability, allow data to be managed more effectively throughout the data life-cycle, and enable reproducible science.

Part I of this tutorial will provide an overview of parallel I/O systems and summarize the key techniques for obtaining high performance I/O on high-performance computing (HPC) resources at scale. Part II introduces the ADIOS library, delving through their usage models and examples, showing how to achieve high performance scalable I/O. Part III explains data compression. Part IV covers techniques for creating in situ analytics and teaches how to generate visualization services. Over one half of this tutorial will be hands-on sessions, where we provide access to the software and go through live examples using a Virtualbox VM. We will have users work with real examples including the heat equation, a brusselator example, and the Gray Scott Model of Reaction Diffusion.

Tutorial 2:
Distributed computing and spatial data analysis in Julia

Presenters:
Bogumił Kamiński, PhD, Associate Professor, SGH Warsaw School of Economics
Przemysław Szufel, PhD, Assistant Professor, SGH Warsaw School of Economics
Abstract:
The goal of this course is to provide hands-on experience for computational scientists to leverage the power of distributed computing and simulations in the Julia language. You are invited to bring a laptop and install the software that will be used during the workshop (see the installation instructions below).
During the workshop we will present practical case study requiring massive computations. Both thread- and process- based parallelization in Julia will be discussed. We will also show how to create various types of distributed computational clusters.
The Julia language use case presented during the workshop will be a multi-agent, large-scale, vehicle routing simulation model that can be used analyze commuter’s behavior in large cities. The numerical simulations will be run on actual road transportation system data taken from the Open Street Map project.
The course assumes intermediate prior knowledge of scientific programming in at least one language (e.g. Python, Gnu R, Java or Julia). In the first part of the tutorial we will provide an introduction to Julia programming. No significant prior knowledge of distributed computing or experience with large-scale simulation models is required.
Important Notes:
  1. Please download Julia from https://julialang.org/downloads/ and follow the installation instructions presented at https://julialang.org/downloads/platform.html
  2. Install Julia packages that will be used throughout the course. In the command line (console) type julia and paste the following Julia code:

    using Pkg
    Pkg.add(“DataFrames”)
    Pkg.add(“PyCall”)
    Pkg.add(“Conda”)
    Pkg.add(“PyPlot”)
    Pkg.add(“Plots”)
    Pkg.add(“CSV”)
    Pkg.add(“LightGraphs”)
    Pkg.add(“IJulia”) # optional for participants wanting to use Jupyter Notebooks

  3. A convenient programming environment for the Julia language is Atom plugin named Juno. In order to install Atom with Juno please follow the steps below:
    1. Download and install Atom (available at https://atom.io/).
    2. Start Atom and press Ctrl + , ( Ctrl key + comma key ) to open the Atom settings screen.
    3. Select the Install tab.
    4. In the Search packages field, type uber-juno and press Enter.
    5. You will see the uber-juno package developed by JunoLab—click Install to install the package.
  4. Optionally, it is possible to use Julia within Jupyter notebook.
    In order to try Julia inside a Jupyter notebook start the Julia console and run the two following commands:

    using IJulia
    notebook(dir=pwd()) # a new web browser tab should open with Jupyter Notebook
    # showing current Julia working directory

Abstract:
Visual analysis is one of the most powerful tools for data exploration and interpretation. It takes advantage of visualization techniques and allows scientists to work with their research data in interactive and intuitive way. In today’s HPC environment and Big Data era, data analysis techniques, together with visualization, gain on importance. However, the amounts of data and the sizes of single datasets impose the need for adequate software tools. In this tutorial we will address this problem by providing participants with strong tool for data processing, visualization and visual analysis – VisNow, an open source generic platform based on data flow paradigm. The goal of this tutorial is to introduce the audience to the concept of visual analysis, show basic ideas of scientific visualization and to go step-by-step through several case studies in hands-on sessions based on our platform. Problems of visualization of common HPC data structures, including 2-D and 3-D, scalar and vector, regular and unstructured data will be covered and adequate elements of the software described to give participants the basics of VisNow usage.
