Numerical Linear Algebra for Scientific High Performance Computing (Wintersemester 2021/22)
- Dozent*in: Dr. Hartwig Anzt
- Veranstaltungen: Vorlesung (2400138), Übung (2400140)
- Semesterwochenstunden: 2+2
Given the current situation, we will realize this lecture as a hybrid event.
The lecture will take place in SR -1.009 (20.30) and will be streamed on
For further information, please contact email@example.com
We will use C / C++ for programming. You are free to use Java or FORTRAN, if you prefer (I recommend C/C++, though!).
The lecture slides will be collected in the git repo
The homework assignments will be available in the git repo

- Precision Formats and Mixed Precision Numerics
The success control takes place in the form of a project presentation and an oral exam of at least 30 minutes duration and evaluation of the written project report and grading of the performance in the exercises.
Composition of the module grade:
The overall grade for a different type of examination is formed as follows:
A total of 200 points can be achieved, that compose of
• a maximum of 60 points for the exercise sheets (10 per exercise sheet),
• a maximum of 60 points for the final presentation including an oral examination,
• A maximum of 80 points for the project implementation and project report.
To pass the success control, at least 140 points must be collected.
