After two successful workshops in 2009 and 2010, also this year the MAC Summer took place. Most of the MAC members, friends - of MAC, TUM, and Advanced Computing - from all over the world, and people interested in MAC and associated activities gathered for the half-day workshop at TUM's Institute for Advanced Study (IAS).

Prior to the official summer workshop, two additional meetings were held as a "warm up": The Munich Multiphysics Meeting and the Peano User Meeting. Though they addressed very specific topics, they were open to all workshop participants.

The Munich Multiphysics Meeting brought together invited experts from the different areas involved in the development of efficient simulation approaches for multiphysics scenarios: engineering, mathematics, computer science, and scientific computing. The main focus of the meeting were common challenges of various multiphysics applications such as convergence, numerical stability, and hardware efficiency. As multiphysics applications typically involve not only different types of physics but also several simulation codes at a time, all these topics involve a lot more aspects and open questions than in the case of singlephysics applications making multiphysics a field of vivid research accross various scientific disciplines.

The second meeting was the Peano User Meeting. Peano is an open source software framework for PDE solvers based upon adaptive Cartesian multiscale grids. A particular focus is on the grid construction, grid management, and parallel grid traversal in dynamically changing settings with very low memory requirements. This meeting was a place for the users and developers of Peano to discuss current changes in the framework, future developments but also to gather improvement suggestions and user feedback.

During lunchtime, several posters, demos, and presentations of affiliated MAC groups could be visited in the foyer of the IAS while in the ITuepferl, TUM's computer science showroom, the FRAVE installed under the umbrella of the KAUST-TUM special partnership project Virtual Arabia was open to all participants to have a look at the recent software developments in several MAC-KAUST projects. Further information on the FRAVE can be found at FRAVE.

For the main afternoon workshop, MAC was proud to have several renowned speakers as guests. After some opening remarks of Patrick Dewilde, Director of the IAS, Tobias Weinzierl, the scientific project manager of the KAUST-TUM projects Simulating CO2 Sequestration and Virtual Arabia, and Hans-Joachim Bungartz, Director of the MAC, Prof. Rainer Helmig (University Stuttgart) talked about Efficient modeling of flow and transport in porous media using multiphysics and multiscale approaches while Prof. Klinker (TUM) gave the audience insights into Augmented and Virtual Reality as 3D User Interfaces to explore simulated or measured data. A special guest was George Biros (Georgia Institute of Technology) who pleased the supercomputing audience with a talk on Massively parallel N-body solvers in heterogeneous architectures.

The official program of the MAC Summer Workshop concluded with the MAC Scientific Summer Party where guests enjoyed dinner, nice music, conversations and caught up with the latest in womens football.
