GTC Europe 2016

gtc_featured_speakers

The elbe team was part of the first European GPU Technology Conference that took place on September 28-29 in Amsterdam, Netherlands. More than 1700 attendees were on site to learn about deep learning, artificial intelligence and high performance computing on graphics processing units. I was one of the featured speakers in the HPC track with my talk about “Number-Crunching on the Desktop for Simulation-Based Design – the Future of Computational Fluid Dynamics”. The talk was recorded and will be available online soon – check http://www.gputechconf.eu for further details.

HANNOVER MESSE 2015

20150414_10285

Meine beiden Vorträge im Rahmen des CAE-Forums auf der HANNOVER MESSE 2015 zu den Themen

“Rechnen auf Grafikkarten – die Zukunft im simulationsgestützten Entwurfsprozess?”

“Vorstellung der Ergebnisse der Umfrage ‘Computing’ (CPU, GPU, HPC und Cloud)”

waren ein voller Erfolg. Der erste Talk befasste sich mit Chancen und Herausforderungen des Einsatzes von Grafikkarten im simulationsgestützten Entwurfsprozess und beinhaltete neben einer kritischen Reflexion der Einsetzbarkeit kommerzieller Softwarelösungen auch die Entwicklungskonzepte und Potentiale unseres hauseigenen Software-Prototypen elbe. Im zweiten Talk ging es um die Ergebnisse einer Meinungsumfrage, die u.a. den im Simulationsbereich vorhandenen Bedarf an High Performance Computing adressierte. Im Speziellen wurden mögliche Konzepte zur Deckung dieses Bedarf diskutiert und zwei Lösungen, Cloud Computing oder GPU-gestützte Beschleunigung, gegenübergestellt.

ONC Tsunami Workshop 2014

In March 2014, 50 years after the 1964 Alaska earthquake and Tsunami, Ocean Networks Canada organized a two-day technical workshop on Tsunami modeling. The workshop covered advanced modeling and prediction technologies for real-time Tsunami forecasting, detection and alerts. In this context, I presented the potential of the elbe solver for efficient and accurate simulations of wave impact and wave-structure interactions in complex three-dimensional topologies, which can be a valuable contribution to Tsunami warning systems in British Columbia.

Further details and the workshop agenda can be found at ONC Tsunami Workshop 2014.

elbe team @ GACM 2013

The elbe team will present the latest advances in the field of visualization and fluid-structure interaction at the 5th GACM Colloquium on Computational Mechanics (GACM 2013):

Monday, 15:20 – 15:40:
Nagrelli, Heinrich: GPGPU-accelerated simulation of wave-ship interactions using LBM and a quaternion-based motion modeler

Tuesday, 13:30 – 13:50
Koliha, Nils: Efficient Grid Generation and On Device Visualization for Massively Parallel GPU Accelerated Lattice Boltzmann CFD Simulations

Monday, 18:10, Poster Session
Koliha, Nils: Efficient Grid Generation and On Device Visualization for Massively Parallel GPU Accelerated Lattice Boltzmann CFD Simulations (Poster/Live Demo)

Moreover, this year’s symposium on Fluid Mechanics is organized by Christian Janßen and Thomas Rung (symposium #12, GACM web page). The symposium features 18 talks in four sessions on Hybrid Methods, the Lattice Boltzmann Method, Optimization, and FEM and ACM. It will take place on Tuesday and Wednesday from 10:30 to 12:10 and from 13:30 to 15:10 in building N, room 0.007 (campus map).
