The FZ HPC will join the ASHPC 2022 conference with two talks and a live demo.

The FZ HPC has co-authored a significant number of Austrian PRACE proposals over the past few years, all of which were accepted. In an effort to continue this focus with the EuroHPC JU, which effectively replaced PRACE, Philipp Gschwandtner will share practical experiences and insights gained while preparing three specific PRACE proposals from different fields of science (astrophysics, climate research, and theoretical chemistry). Furthermore, the talk will illustrate the most significant changes between computing access proposals of PRACE and the EuroHPC JU. The talk is scheduled for Tuesday, May 31st 2022, 10:00.

In the second, contributed talk, we will present our Cluster Coffer, our minature supercomputer for public outreach and teaching parallel programming and HPC. In this talk, we will discuss relevant details regarding its hardware design and construction, as well as software stack decisions and benchmarking with regard to the two main HPC benchmarks used for performance testing, HPL and HPCG. Finally, two use cases for teaching and public outreach are presented and analyzed. This talk is scheduled for Wednesday, June 1st 2022, 15:05.

Finally, Philipp Gschwandtner will show a live demo of the Cluster Coffer at the conference poster session. In order to demonstrate the type of applications running on supercomputers, the Cluster Coffer performs a space weather simulation. This simulation computes the trajectories of solar wind particles coming from our Sun and how they interact with electromagnetic fields as emanated by the Earth. However, instead of simply simulating particles coming from our Sun, the public is actively involved in the simulation, as their motions are captured through a webcam and provided as input to the simulation. In return, the particles position and velocity are visualized live in 3D. The live demo is scheduled for Wednesday, approximately 17:00.
