Talk: CP Violation Part III: More Theory

Slides: 17
Duration: 60 Minutes
Occasion: PhD students physics seminar
Location: Forschungszentrum Jülich
Date: 16.10.2014
Background of Audience: Physicists, PhD students

Third part of my lecture on CP violation. This time on the menu: CKM matrix, the different parameterizations (the usual with sin / cos; the Wolfenstein one), and the unitarity triangle.
Liked it! Although I, still, severely lack depth in knowledge on the topic, burying into a unknown physics theory is, still, a lot of fun.

I made a GIF animation of the CKM fitter results of the last few years. You find it after the jump.

Talk: GPU-based Online Tracking for the PANDA Experiment

Slides: 48
Duration: 45 Minutes
Occasion: NVIDIA Application Lab Workshop 2014
Location: Jülich Supercomputing Centre
Date: 8.10.2014
Background of Audience: GPU experts and novices, HEP not-at-all’er

Second talk to report the progress we did in the course of the last year when working together with the Application Lab. The latest results from the paper submission are in (all the while there are still some more latest-er results missing…).

As I had a 45 minutes time slot I brought some exhibitions of our STT detector. I like to do that, to show people we’re not only programming stuff for heating up Silicon, but to actually interact with some real life application.

Official place to find these and other slides.

Talk: GPU-based Online Tracking for the PANDA Experiment [GPU at HEP 2014]

Slides: 37
Duration: 30 Minutes
Occasion: GPU Computing at High Energy Physics, September 2014, GPUs at Low Level Trigger session
Location: Pisa University, Italy
Date: 11.9.2014
Background of Audience: GPU enthusiasts, HEP physicists. No need to waste time introducing stuff.

Usual talk with some new animations introducing Hough transforms and explaining my current Hough space peak finding status.

After the jump I included the GIFs of the animations in this post. The PDF has static, ›keyframe‹ version of them. During the actual presentation I showed the GIFs.

Talk: Enabling the Next Generation of Particle Physics Experiments: GPUs for Online Track Reconstruction

Slides: 38
Duration: 25 Minutes
Occasion: Dresden CUDA Center of Excellence‘s Workshop on Fast Data Processing on GPUs
Location: TU Dresden, Germany
Date: 15.5.2014
Background of Audience: Computer scientists, GPU enthusiasts

As you can guess form the title of the talk, it was exactly the same talk as I held at the GPU Tech Conference. Go over there to look at the slides.
The only thing new: My part for the »Bring your own GPU challenge« session. In the PDF, after the Thank You slide, you find some Hough spaces where I explained my challenge of finding peaks in a parallel fashion. More to that in the week’s review post.

My talk was good, the workshop as well. Unfortunately the last two talks were cancelled and I had to wait more than five ours until my flight would leave :(.

Talk: Online Tracking on GPUs at PANDA

Slides: 29
Duration: 25 Minutes
Occasion: Fifth International Workshop for Future Challenges in Tracking and Trigger Concepts 2014
Location: Frankfurt Institute for Advanced Studies, FIAS, Frankfurt, Germany
Date: 13.5.2014
Background of Audience: Physicists working on tracking — experts!

Usual talk sans tracking introduction, as there was an audience full of tracking experts. People were curious on some of the aspects I presented and the experience we gained. Good!
The other talks were also quite good, maybe a bit too deep-level for me (focusing on vectorization and very specific applications). At the end (and also in between) there was quite a fruitful discussion.

Talk: Enabling the Next Generation of Particle Physics Experiments: GPUs for Online Track Reconstruction

Slides: 37
Duration: 25 Minutes
Occasion: GPU Technology Conference 2014, Session S4499
Location: Room 212A, McEnery Convention Center, San José, CA, USA
Date: 26.3.2014
Background of Audience: Computer Scientists

Talk at NVIDIA’s conference for GPU-using developers (usually, everything but gaming). Not too big of an audience, unfortunately.
I (intentionally) spend a lot of time introducing the topic, as most of the people in the audience don’t know anything about particle physics and tracking and stuff.

On the GTC page, there’s a recording of the session, unfortunately with the wrong aspect ratio1 – you find a fixed version at the end of this post. The slides accompanying my talk on the NVIDIA side are a cut-down to print version (= less animations).
In the full PDF version provided here you can click on the nearly-hidden links to more in-depth backup slides on some topics (located next to the page number on its left-hand side – e.g. on slide #33.)

  1. I even made my slides in 16:9 format at the first day of the conference!
