Goals

Development of key components of a concurrent framwork using as starting point the  existing Gaudi framework. The ultimate deliverables would be a set of components or libraries that can be used in any framework and at the same time to offered as a complete turnkey system with all these integrated.

Milestones

1. Integration of the Concurrent Whiteboard demonstrator into Gaudi and characterisation of its performance (2012Q4)
2. Run a restricted set of algrithms (Mini-Brunel) with the GaudiHive framework (2013Q2)
