Computing with Light

There are high hopes for photonic computing, particularly in the context of artificial intelligence (AI) applications. Photonic systems, such as those installed at the LRZ by Q.ANT, reduce the energy requirements for computer vision considerable. The start-up from Stuttgart will be presenting its technology at #SC25.

Photonic Computing

HPC + Research = Art

With the help of HPC, research results can become a feast for the eyes: At #SC25 Art + HPC, Elisabeth Mayer from the Centre for Virtual Reality & Visualisation at the LRZ will present her work "Within the Marble", which shows millions of years of Earth's history in fast motion and illustrates geophysical data using cinematic techniques.

Art of HPC

Turbulence in the Universe

In a groundbreaking simulation, a research team demonstrates how energy changes within interstellar turbulence (picture: J. Beattie/Princeton University). This shifts our understanding of galaxy formation and reveals the spread of cosmic radiation and magnetic fields. The simulation was computed and visualised at the LRZ.
