Bachelor‘s thesis presentation. Kevin is advised by Keerthi Gaddameedi.
SCCS Kolloquium
The SCCS Colloquium is a forum giving students, guests, and members of the chair the opportunity to present their research insights, results, and challenges. Do you need ideas for your thesis topic? Do you want to meet your potential supervisor? Do you want to discuss your research with a diverse group of researchers, rehearse your conference talk, or simply cheer for your colleagues? Then this is the right place for you (and you are also welcome to bring your friends along).

Kevin Adameit: Parameter Evaluation of the Parallel Full Approximation Scheme in Space and Time (PFASST)
SCCS Colloquium |
Partial differential equations (PDEs) are essential for modeling various physical processes, such as atmospheric dynamics and the diffusion of heat in space and time. Since analytical solutions
are often unavailable or too complex to compute, numerical methods are required to solve PDEs. These methods discretize PDEs in space, using approaches such as finite volume, finite element, or spectral methods, and combine them with time integration schemes, such as Runge-Kutta methods. Since numerically solving PDEs requires significant computational effort, techniques have been developed to efficiently solve the equations in parallel on High-Performance-Computing (HPC) systems.
The Parallel Full Approximation Scheme in Space and Time (PFASST) is a parallel-in-time method addressing the current saturation of spatial parallelization in HPC, by introducing parallelization in the temporal domain. PFASST combines the high-order Spectral Deferred Correction (SDC) method in its multi-level form MLSDC, allowing efficient parallelization in space and time. While PFASST has been shown to be both robust and scalable, it is also computationally demanding. Therefore, recent research has focused on dynamically adapting assigned computational resources during PFASST execution, allowing efficient resource manage-
ment. The open-source Fortran implementation LibPFASST has already been enhanced with an interface for this purpose. However, systematic criteria for resource adaptions are still missing. This thesis evaluates the influence of PFASST parameters on the accuracy of solutions and runtime of the solving process to provide a basis for dynamic resource management criteria. To this end, we conducted investigative experiments with LibPFASST on the Dahlquist test equation, the two-dimensional heat equation, and the two-dimensional advection equation. Our analysis focused on the influence of increasing the degree of temporal parallelization in
PFASST on accuracy and runtime, as well as its weak scaling and strong scaling behavior. The parameters which we considered in this context are number of processors, time step size, number of quadrature nodes and spatial points on the different coarsening levels, and number of sweeps in prediction and iteration phase.

Contribute a talk
To register and schedule a talk, you should fill the form Colloquium Registration at least four weeks before the earliest preferred date, at the end of a semester typically even earlier reservation is necessary due to a very high influx of presentations. Keep in mind that we only have limited slots, so please plan your presentation early! In special cases, contact colloquium(at)mailsccs.in.tum.de.
Colloquium sessions are now on-campus. We have booked room MI 02.07.023 for SS25 and MI 00.13.054 for WS25/26. You can either bring your own laptop or send us the slides as a PDF ahead of time. The projector only has an HDMI connection, so please bring your own adapters if necessary.
We invite students doing their Bachelor's or Master's thesis, as well as IDP, Guided Research, or similar projects at SCCS to give one 20min presentation to discuss their results and potential future work. The time for this is typically after submitting your final text. Check also with your study program regarding any requirements for a final presentation of your project work.
New: In regular times, we will now have slots for presenting early stage projects (talk time 2-10min). This is an optional opportunity for getting additional feedback early and there is no strict timeline.
Apart from students, we also welcome doctoral candidates and guests to present their projects.
During the colloquium, things usually go as follows:
- 10min before the colloquium starts, the speakers setup their equipment with the help of the moderator. The moderator currently is Ana Cukarska. Make sure to be using an easily identifiable name in the online session's waiting room.
- The colloquium starts with an introduction to the agenda and the moderator asks the speaker's advisor/host to put the talk into context.
- Your talk starts. The scheduled time for your talk is normally 20min with additional 5-10min for discussion.
- During the discussion session, the audience can ask questions, which are meant for clarification or for putting the talk into context. The audience can also ask questions in the chat.
- Congratulations! Your talk is over and it's now time to celebrate! Have you already tried the parabolic slides that bring you from the third floor to the Magistrale?
Do you remember a talk that made you feel very happy for attending? Do you also remember a talk that confused you? What made these two experiences different?
Here are a few things to check if you want to improve your presentation:
- What is the main idea that you want people to remember after your presentation? Do you make it crystal-clear? How quickly are you arriving to it?
- Which aspects of your work can you cover in the given time frame, with a reasonable pace and good depth?
- What can you leave out (but maybe have as back-up slides) to not confuse or overwhelm the audience?
- How are you investing the crucial first two minutes of your presentation?
- How much content do you have on your slides? Is all of it important? Will the audience know which part of a slide to look at? Will somebody from the last row be able to read the content? Will somebody with limited experience in your field have time to understand what is going on?
- Are the figures clear? Are you explaining the axes or any other features clearly?
In any case, make sure to start preparing your talk early enough so that you can potentially discuss it, rehearse it, and improve it.
