Numerical Linear Algebra for Scientific High Performance Computing (Winter Semester 2020/21)
- Lecturer: Dr. Hartwig Anzt
- Classes: Lecture (0110650)
- Weekly hours: 2
In this course, we will cover different aspects of scientific high performance computing:
- Methods and algorithms for scientific HPC
- Programming models and languages for HPC (CUDA, HIP, OpenMP, DPC++, MPI)
- Understanding and optimizing performance on HPC systems
- Sustainable Software Development
The course will be virtual: https://kit-lecture.zoom.us/j/67845776476
Lecture slides will be collected in the git repo: https://git.scc.kit.edu/nla4hpc_winter20-21/lecture-slides.git

BLAS operations, LAPACK, ScaLAPACK, LU/QR/Cholesky decomposition, Singular Value Decomposition (SVD)
Iterative Sparse Linear Algebra:
Fix-Point Iteration, Kylov subspace methods, ILU preconditioning, Jacobi/block-Jacobi preconditioning, Finite differences (Laplace), Domain Decomposition Methods (Additive/Multiplicative Schwarz)
- Focus on sustainable software development.
- Homework will be peer-reviewed by other students and both the homework and the peer review performance will be graded.
- Homework usually includes programming, performance experiments, and a report.
- Programming in C/C++ (+ we learn CUDA, OpenMP, HIP)
- 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 an 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).
