Parallel Programming of High Performance Systems

Date: Monday, March 06 - Friday, March 10, 2017, 9:00-18:00
Location: LRZ Building, University campus Garching, near Munich, Kursraum 2
Contents:

This course, a collaboration of Erlangen Regional Computing Centre (RRZE) and LRZ, is targeted at students and scientists with interest in programming modern HPC hardware, specifically the large scale parallel computing systems available in Jülich, Stuttgart and Munich.

Each day is comprised of approximately 4 hours of lectures and 3 hours of hands-on sessions.

Tentative schedule:

Day 1

  • Introduction to High Performance Computing (Weinberg)
  • Secure shell (Weinberg)
  • Source code versioning with SVN (Navarrete)
  • Handling console and GUI based interfaces (Weinberg)
  • Building programs with GNU MAKE (N.N.)

Day 2

  • Basic parallel programming models: elements of MPI and OpenMP (Weinberg)
  • Basics of software engineering (Navarrete)
  • Processor architectures (Hager)

Day 3

  • Principles of code optimization: unrolling, blocking, dependencies, C++ issues, bandwidth issues, performance projections (Hager)
  • Advanced OpenMP programming (Weinberg)

Day 4

  • Parallel architectures: multi-core, multi-socket, ccNUMA, cache coherence and affinity, tools for handling memory affinity (Hager)
  • Parallel algorithms: data parallelism, domain decomposition, task parallelism, master-worker, granularity, load balancing, scalability models (Hager)
  • Advanced MPI programming (Wittmann)

Day 5

  • Intel tools: OpenMP performance and correctness (Wittmann)
  • Intel tools: MPI tracing and Checking (Karmakar)
  • Intel VTune (Baruffa)
  • Performance analysis with Score-P and Scalasca (Karmakar)
Prerequisites Good working knowledge of at least one of the standard HPC languages: Fortran 95, C or C++.
