摘要： An interconnection network comprises a pair of backplanes for receiving X pluggable node cards. The pair of backplanes include X backplane connector groups, each backplane connector group adapted to receive mating connectors from a pluggable node card. Each backplane connector group includes X/2 connectors. A first backplane includes first permanent wiring which interconnects a first subset of pairs of connectors between backplane connector groups. A second backplane includes second permanent wiring which interconnects a second subset of pairs of connectors between backplane connector groups. The first permanent wiring and second permanent wiring connect complementary subsets' of pairs of the connectors. A plurality of node cards, each including a card connector group, pluggably mate with the backplane connector groups. Each node card further includes a frontal connector that is adapted to receive a cable interconnection. Each node card includes a processor and a switch module which simultaneously connects the processor to at least plural connectors of a backplane connector group.

摘要： A multi-nodal data processing system includes a plurality of processing nodes, each node connected to plural other nodes by bidirectional data links. Each node comprises receivers for receiving messages on bidirectional data links and transmitters for transmitting messages on bidirectional data links. Each node records child nodes to which a message was transmitted and is further adapted to transmit a lock-up message received from a child node to a parent node, the lock-up message indicating a successful establishment of a message signal path to a destination node. Each node further is adapted to transmit a link cancel signal to another node to close the link in the event of an unsuccessful message transfer attempt over the link. Each node inhibits transmission of a lock-up signal to a parent node until link cancel signals have been received from all child nodes (other than a node from which a lock-up signal was received). A source node (where a message originates) continues transmission of its message, even before a lock-up signal has been received. The destination node which originates the lock-up message terminates a bidirectional data link by an end-of-session signal when it has received an entire message.
摘要翻译：多节点数据处理系统包括多个处理节点，每个节点通过双向数据链路连接到多个其他节点。每个节点包括用于在双向数据链路上接收消息的接收机和用于在双向数据链路上发送消息的发射机。每个节点记录发送消息的子节点，并且进一步适于将从子节点接收的锁定消息发送到父节点，锁定消息指示成功建立到目的地节点的消息信号路径。每个节点进一步适于在另一节点上发送链路取消信号以在通过链路的不成功的消息传送尝试的情况下关闭链路。每个节点禁止向父节点发送锁定信号，直到从所有子节点（除了接收到锁定信号的节点）接收到链路消除信号为止。即使在接收到锁定信号之前，源节点（消息始发地）也继续发送其消息。当接收到整个消息时，发起锁定消息的目的地节点通过会话结束信号终止双向数据链路。

摘要： A computing system includes plural nodes that are connected by a communications network. Each node comprises a communications interface that enables an exchange of messages with other nodes. A ready queue is maintained in a node and includes plural message entries, each message entry indicating an output message control data structure. The node further includes memory for storing plural output message control data structures, each including one or more chained further monrtol data structures that define data comprising a message or a portion of a message that is to be dispatched. Control data structures that are chained from an output messsage control data structure exhibit a sequence dependincy. A processor is controlled by the ready queue and enables dispatch of portions of the message designated by an output message control data structure and associated further control structures. The processor prevents dispatch of one portion of a message prior to dispatch of another portion of the message upon which the first portion is dependent even if message transmissions are interrupted.
