摘要： A method for communicating between nodes of a plurality of nodes is disclosed. Each node includes a plurality of processors and an interconnect chipset. The method issues a request for data from a processor in a first node and passes the request for data to other nodes through an expansion port (or scalability port). The method also starts an access of a memory in response to the request for data and snoops a processor cache of each processor in each node. The method accordingly identifies the location of the data in either the processor cache or memory in the node having the processor issuing the request or in a processor cache or memory of another node.

摘要： The present invention is directed to a method and apparatus for scheduling a resource to meet quality of service guarantees. In one embodiment of three levels of priority, if a channel of a first priority level is within its bandwidth allocation, then a request is issued from that channel. If there are no requests in channels at the first priority level that are within the allocation, requests from channels at the second priority level that are within their bandwidth allocation are chosen. If there are no requests of this type, requests from channels at the third priority level or requests from channels at the first and second levels that are outside of their bandwidth allocation are issued. The system may be implemented using rate-based scheduling.

摘要： Methods and apparatuses are described for a communication system. The communication system comprises an initiator core supporting a first burst capability as well as a target core supporting a second burst capability. The supported burst features of the second burst capability differ from the supported burst features of the first burst capability. The communication system also comprises an agent coupled to the initiator core, which comprises logic to compute target-dependent burst support information across multiple groups of potential targets at the same time. The logic then selects the correct target-dependent information based upon a resulting address decode for the target selection.

摘要： A split sparse directory for a distributed shared memory multiprocessor system with multiple nodes, each node including a plurality of processors, each processor having an associated cache. The split sparse directory is in a memory subsystem which includes a coherence controller, a temporary state buffer and an external directory. The split sparse directory stores information concerning the cache lines in the node, with the temporary state buffer holding state information about transient cache lines and the external directory holding state information about non-transient cache lines.

摘要： A computer architecture for avoiding a deadlock condition in an interconnection network comprises a messaging buffer having a size pre-calculated to temporarily store outgoing messages from a node. Messages are classified according to their service requirements and messaging protocols, and reserved quotas in the messaging buffer are allocated for different types of messages. The allocations of the reserved quotas are controlled by a mechanism that, to prevent overflow, limits the maximum number of messages that can be outstanding at any time. The messaging buffer is sized large enough to guarantee that a node is always able to service incoming messages, thereby avoiding deadlock and facilitating forward progress in communications. The buffer may be bypassed to improve system performance when the buffer is empty or when data in the buffer is corrupted. In addition, a multicast engine facilitates dense packing of the buffer and derives information from a message header to determine whether there is a multicast to perform and to permit passage of messages. Other considerations to reduce the buffer size are incorporated.
摘要翻译：用于避免互连网络中的死锁状况的计算机体系结构包括具有预先计算以便临时存储来自节点的传出消息的大小的消息传送缓冲器。消息根据其服务要求和消息协议进行分类，消息缓冲区中的保留配额被分配给不同类型的消息。保留配额的分配由一种机制来控制，为了防止溢出，可以限制任何时候可以发送的最大消息数。消息传递缓冲区的大小足够大，以确保节点始终能够服务传入的消息，从而避免死锁并促进通信的前进进程。当缓冲区为空或缓冲区中的数据被破坏时，可能会旁路缓冲区以提高系统性能。此外，多播引擎促进了缓冲器的密集打包，并从消息头部导出信息，以确定是否存在要执行的多播并允许消息通过。纳入了减少缓冲区大小的其他考虑因素。
