Parallel Programming of High Performance Systems @ RRZE

Date: Monday, March 12 - Friday, March 16, 2018, 9:00-18:00
Location: RRZE Building, University Campus Erlangen, Martensstr. 3, 91058 Erlangen, room 02.135

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)
  • Handling console and GUI based interfaces (Weinberg)
  • Source code versioning with SVN and GitLab (Martone)
  • Building programs with GNU MAKE (Martone)

Day 2

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

Day 5

  • Intel tools: OpenMP performance and correctness (Wittmann)
  • Performance analysis with Score-P and Scalasca (Navarrete)
  • Intel tools: MPI tracing and Checking (Iapichino)
  • Intel VTune (Iapichino)
Prerequisites Good working knowledge of at least one of the standard HPC languages: Fortran 95, C or C++.
Language: English
Teachers: G. Hager, M. Wittmann (RRZE), L. Iapichino, M. Martone, C. Navarrete, V. Weinberg (LRZ)

Via the LRZ registration form.


The exercises will be done on the teramem system at LRZ.
