Content

High Performance Computing has become a critical success factor in research and industry. Even the computational power of commodity parts like desktop systems increased rapidly due to vectorization, EPIC, multi-core. This lab course uncovers the principles behind these buzzwords and highlights programming concepts, software design and coding styles which are mandatory to unleash the power of modern chips.

We focus on developing datastructers and algorithms with respect to their performance, for both single and parallel executions. We deep-dive into different platforms like CPUs, coprocessors and multi-node clusters. Furthermore, we cover several programming concepts like auto-vectorization, explicit vectorization, OpenMP and MPI. The platform differences are evaluated through detailed runtime experiments.

Topics:

  • Performance-Optimization of sequential applications
    • Pipelining
      • Loop unrolling
      • Data dependencies
    • Caches
      • Cache blocking
    • Performance-Measurement
  • State-of-the-Art Hardware
    • CPUs
    • Memory Subsystems
    • Supercomputer
    • Xeon Phi coprocessor
  • Parallele Programming
    • OpenMP
    • MPI

The course is held in two parts. The first one introduces basics, concepts and programming models through theoretical and practical exercises. You work on these exercise in small teams. The second part is a real-life task: each team has to optimize a given scientific application with respect to the underlying hardware architecture.

C-Programming and Linux Know-How are helpful!
