Numerische Lineare Algebra für das wissenschaftliche Rechnen auf Hochleistungsrechnern (Winter Semester 2017/18)

Lecturer: Dr. Hartwig Anzt
Classes: Lecture (0110650)
Weekly hours: 2


Building 20.30, Room 3.61
Wednesday, 2pm - 3:30 pm

Contact: hartwig.anzt@kit.edu SEND ME AN EMAIL IF YOU WANT TO TAKE THIS CLASS!
Office Hours: after the course, or by appointment (Office 3.017 in 20.30)

We will use C / C++ as programming language. You are free to use Java or FORTRAN, if you prefer (I recommend C, though!).

You need access to computing resources (including an NVIDIA GPU). If you don’t have, please ping me.

Examination

Homework:

  • Usually weekly (2 weeks for completion).
  • Lowest grade will be dropped.
  • Must be sent in on time (no late assignments).
  • Don’t copy someone else’s work.
  • Can include programming, theoretical work, running a program, but always a detailed documentation and analysis.
  • Programming in C, FORTRAN, Java.
  • Send the complete assignment package (code + instructions + documentation/ analysis) to hartwig.anzt@kit.edu.

Project:

  • Topic of general interest to the course.
  • The idea is to read three or four papers from the literature (references will be provided).
  • Implement the problem/application.
  • New ideas and extensions are welcome, as well as optimized implementations of existing algorithms.
  • I.e., the class project can be a HPC implementation of a different project you are working on (Master’s thesis, Seminar, etc.)
  • I will also distribute a list with project ideas.
  • Synthesize them in terms of a report (~10-15 pages).
  • Present your report to class (~30 mins).
  • Presentation accounts for 30% of final grade.
  • Project paper accounts for 40% of final grade.
