Course information

Content and learning outcomes

Course contents *

  • Basic ideas including hardware architectures, memory hierarchies, communications,
    parallelization strategies, measures of efficiency;
  • HPC and Green Computing;
  • Introduction to MPI, the Message Passing Interface;
  • Simple numerical algorithms including matrix operations, Gaussian elimination;
  • Algorithms on graphs including graph partitioning problems;
  • Parallel sorting;
  • More advanced parallel algorithms;
  • Standard libraries;

Intended learning outcomes *

The overall goal of the course is to provide a basic understanding of how to develop algorithms and how to implement them in distributed memory computers using the message-passing paradigm.

This understanding means that after the course you are able to

  • explain parallelization strategies;
  • find properties of a given problem which may be used for potential parallelization;
  • select and/or develop an algorithm for solving a given problem which has the
    potential for an efficient parallelization;
  • select and/or develop data structures for implementing parallel computations;
  • theoretically analyze a given parallel algorithm with respect to efficiency;
  • implement a given algorithm on a distributed-memory computer using the message passing library MPI;
  • understand the message flow and avoid unwanted situations (e.g. deadlock, synchronization delays);
  • modify and adapt a set of basic routines to special situations;
  • experimentally evaluate the performance of a parallel program;
  • explain differences between the theoretically expected performance and the practically observed performance;
  • independently solve a more complex problem and present your results in a report;
  • are able to run programs on high-performance computers;
  • understand challenges of Green Computing in HPC.
