This will be a two-day event at Universitat Politècnica de Catalunya, Barcelona on Thursday and Friday March 19/20, 2015.

The LDBC FP7 EC funded project is reaching its finalisation, and this will be the last event sponsored directly by the project. However, tasks within LDBC will continue based on the LDBC independent organisation. The event will basically set the following aspects:

• Two day event with one day devoted to User's experiences and one day devoted to benchmarking experiences.
• Presentation of the first benchmarking results for the different benchmarks.
• Interaction with the new LDBC Board of Directors and the whole new LDBC organisation officials.
• Pre-event with the 3rd Graph-TA workshop organised on March 18th at the same premises, with a lot of interaction and interesting research presentations.

Getting there

Flying: Barcelona airport is situated 12 km from the city. There are several ways of getting from the airport to the centre of Barcelona, the cheapest of which is to take the train located outside just a few minutes walking distance past the parking lots at terminal 2 (there is a free bus between terminal 1 and terminal 2, see this map of the airport). It is possible to buy 10 packs of train tickets which makes it cheaper. Taking the bus to the centre of town is more convenient as they leave directly from terminal 1 and 2, however it is more expensive than the train.

Rail: The Renfe commuter train leaves the airport every 30 minutes from 6.13 a.m. to 11.40 p.m. Tickets cost around 3€ and the journey to the centre of Barcelona (Sants or Plaça Catalunya stations) takes 20 minutes.

Bus: The Aerobus leaves the airport every 12 minutes, from 6.00 a.m. to 24.00, Monday to Friday, and from 6.30 a.m. to 24.00 on Saturdays, Sundays and public holidays. Tickets cost 6€ and the journey ends in Plaça Catalunya in the centre of Barcelona.

Taxi: From the airport, you can take one of Barcelona's typical black and yellow taxis. Taxis may not take more than four passengers. Unoccupied taxis display a green light and have a clearly visible sign showing LIBRE or LLIURE. The trip to Sants train station costs approximately €20 and trips to other destinations in the city cost approximately €25-30.

Train and bus: Barcelona has two international train stations: Sants and França. Bus companies have different points of arrival in different parts of the city. You can find detailed information in the following link: http://www.barcelona-airport.com/eng/transport_eng.htm
