ECS Workshop Aachen

March 6-7 2012, Aachen, Germany

The aim of the G8 ECS (Enabling Climate Simulation at Extreme Scale) project is to investigate how to run efficiently climate simulations on future Exascale systems and get correct results. This project gathers top researchers in climate and computer science to focus on three main topics: (i) how to complete simulations with correct results despite frequent system failures, (ii) how to exploit hierarchical computers with hardware accelerators close to their peak performance and (iii) how to run efficient simulations with 1 billion threads. This project was funded as part of the G8 Research Councils Initiative on Multilateral Research, Interdisciplinary Program on Application Software towards Exascale Computing for Global Scale Issues.

The annual 2-day project meeting will take place in Aachen (Aix-la-Chapelle), Germany, March 6th + 7th. The workshop location is the Aquis Grana Hotel in the city center of Aachen. It offers reduced rates for workshop participants at 89 Euro/night. To take advantage of the reduced rate, please mention the keyword "G8 ECS" when making your reservation by phone (+49-241-4430) or email. The fee for the conference room including lunches, snacks, and drinks on both days is 100 Euro per person. Participants are also expected to cover travel and lodging expenses. The meeting fee must be paid by each participant together with the hotel bill. Participants without hotel room pay only the fee.

Registration is required until February 15, 2012.
Reduced hotel rates are reserved until February 15 and must be booked separately.

Travel Information

We recommend that visitors from America and Japan arrive at Frankfurt Airport (FRA) and take the train to Aachen. There is a train station directly at the airport. Depending on the schedule, you might be able to secure a direct train connection. Otherwise, you have to change the train in Cologne. For train schedules and tickets, please visit the Deutsche Bahn web page or consult your local travel agency. (For the Frankfurt airport train station, please enter "Frankfurt(M) Flughafen Fernbf". The destination in Aachen is called "Aachen Hbf".)

As an alternative to Frankfurt, you can also arrive at the airport in Brussels, take a local train to Brussels and continue with the Thalys high-speed train to Aachen. The Thalys first class has free WLAN.


Visitors from France can take the Thalys train from Paris or fly to Cologne or Duesseldorf. Aachen can be reached by train from there.

The Workshop Hotel Aquis Grana is in 15 min walking distance from the train station Aachen Hbf and it is most convenient to reach it by taxi.

For further details / alternatives, please visit the the GRS web page or contact our team assistant.

Parking Possibilities: The Aquisgrana hotel has own parking spaces but they cannot be reserved in advance. So there is the risk that there are no parking spaces available upon arrival. Alternatively, you can park your car at the car park Büchel (opposite the hotel). There you have to pay a certain daily fee.
