Abstract
Un sistema informático (6) (NUMA) coherente con dispositivos caché, que comprende: una interconexión de nodos (22); y al menos un nodo de proceso local y un nodo de proceso hogar remoto que están acoplados cada uno a dicha interconexión de nodos (22), incluyendo dicho nodo de proceso local una interconexión local (16), un procesador y una memoria del sistema acoplados a la interconexión local, y un controlador de nodo (20) interpuesto entre dicha interconexión local (16) y dicha interconexión de nodos (22), donde dicho controlador de nodo transmite especulativamente una transacción de solicitud de lectura recibida a partir de dicha interconexión local (16) a dicho nodo de proceso hogar remoto mediante dicha interconexión de nodos (22) si dicho nodo de proceso local no es un nodo hogar para los datos solicitados, caracterizado porque dicho controlador de nodo (20) de dicho nodo de proceso local descarta los datos recibidos desde dicho nodo de proceso hogar remoto si dichos datos solicitadosestán en una memoria caché en dicho nodo de proceso local en un estado modificado o compartido.
