  • Component/Virtual Dspin Network

    v1 v2  
    44
    55== 1) Functional Description ==
    6 
    7 It is composed of two [wiki:Component/VirtualDspinArray VirtualDspinArray] , one for command paquets and the other for response paquets.
     6The Virtual Dspin Network aims to connect a two-dimensionnal array of TSAR clusters together.
     7It virtualizes two virtual channels (usually the primary channel and the memory-coherence channel) on two physical networks [wiki:Component/VirtualDspinArray VirtualDspinArray] of different size (usually one for command paquets and one for response paquets).
     8It implements the optimized and confined broadcast protocol and the Hypertransport routing.
