ASEArch - Algorithms and Software for Emerging Architectures

Study group: Future-proof parallelisation of multi-block structured grid codes

April 25-26, 2013 (near Oxford)

The first CCP ASEArch Study Group “Future-proof parallelisation of multi-block structured grid codes” took place at the Weston Manor Hotel near Oxford on April 25-26, 2013. Meeting notes can be found in this link. The agenda is shown below with some links to the presentations on the day.
