The lecture will have a focus on parallel algorithms and implementation techniques in the field of numerical simulation and high performance computing, such as:
- linear algebra problems on dense and sparse matrices
- simulation on structured and unstructured meshes
- particle-based simulations (with long-range and short-range interactions)
- spectral methods (parallel FFT and related algorithms)
- Monte Carlo and statistical methods
(a.k.a. the seven dwarfs of HPC).
The accompanying tutorials will include practical assignments, and will concentrate on the programming of GPU and accelerator platforms.
Slides and exercise sheets/solutions will be made available during the lecture.
Lecture slides will be published here after the lessons: See also the lecture from winter term 2012/13.
- Oct 21: Intro
- Oct 21, Oct 28, Nov 4: Fundamentals - Parallel Architectures, Models, and Languages
- additional material: Roofline: An Insightful Visual Performance Model for Floating-Point Programs and Multicore Architectures (technical report by Williams et al.)
- MPI examples: Cannon's Algorithm mpi_cannon.c (unsafe send/receive), mpi_cannon_sr.c (using MPI_Sendrecv), mpi_cannon_nbl.c (non-blocking communication)
- Oct 28, Nov 4, Nov 11: Dwarf No. 1 - Dense Linear Algebra;
Roughly every second week a two hour tutorial will take place (details at page top; days and time will be announced here and in the lectures). The assignments and their solutions will be gradually posted here.

Helpful, but not strictly required is knowledge in:
- basics of numerical methods (e.g.: lecture IN0019 Numerical Programming or similar)
- basics of parallel programming (lecture Parallel Programming, HPC - Programming Paradigms and Scalability, or similar)
Most important is a certain interest in problems from scientific computing and numerical simulation!
