VirtualDspinNetwork

1) Functional Description

The Virtual Dspin Network aims to connect a two-dimensionnal array of TSAR clusters together. It virtualizes two virtual channels (usually the primary channel and the memory-coherence channel) on two physical networks VirtualDspinArray of different size (usually one for command paquets and one for response paquets). It implements the optimized and confined broadcast protocol and the Hypertransport routing.
