Guided research presentation. Jinwen is advised by Vikas Kurapati, Sebastian Wolf and Prof. Dr. Michael Bader.
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).

Jinwen Pan: Performance Evaluation of Acoustic Material Implementation in SeisSol Using Roofline Model
SCCS Colloquium |
SeisSol is a high-performance computational seismology software to simulate complex earthquake scenarios. It supports various rheologies (elastic, anisotropic elastic, acoustic, viscoelastic, poroelastic), boundary conditions and dynamic rupture laws. The software uses high-order discontinuous Galerkin discretisation with an Arbitrary DERivative (ADER) local time stepping on unstructured adaptive tetrahedral meshes to approximate complex 3D model geometries (faults & topography) and allow rapid model generation. SeisSol follows an MPI+X parallelisation, supporting OpenMP and CUDA (SYCL upcoming) for heterogeneous compute nodes, and exhibits excellent performance and scalability on a suitable range of supercomputing platforms. In the current implementation of SeisSol, an acoustic material is implemented as a subset of elastic material where pressure is equivalent to the normal stresses. This means that all the 9 degrees of freedom (DOFs) pertaining to acoustic materials are required to be updated during the computation even though 4 DOFs are sufficient in practice. Throughout this Guided Research project, we intend to assess the performance of an implementation of the set of acoustic equations with only 4 DOFs using the roofline model and evaluate the performance improvement in comparison to the present 9-DOF implementation.

Contribute a talk
To register and schedule a talk, you should fill the form Colloquium Registration at least two weeks before the earliest preferred date. Keep in mind that we only have limited slots, so please plan your presentation early. In special cases, contact colloquium@mailsccs.in.tum.de.
Colloquium sessions are now on-campus. We have booked room MI 00.13.054 for WS24/25. 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.
Do you want to attend but cannot make it in person? We now have a hybrid option. Simply join us through this BBB room: https://bbb.in.tum.de/shu-phv-eyq-rad
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.
