摘要： A method and apparatus for implementing a snoop filter unit associated with a single processor in a multiprocessor system. The snoop filter unit has a plurality of ports, each port receiving snoop requests from exactly one dedicated source. Associated with each port is a snoop cache filter that processes each snoop cache request and records addresses of the most recent snoop requests for exactly one source. The snoop cache filter uses vector encoding to record the occurrence of snoop requests for a sequence of consecutive cache lines. All addresses of snoop requests are added to the snoop cache unless a received snoop cache request matches an entry present in the associated snoop cache, in which case the snoop request is discarded. Otherwise, the associated snoop cache request is enqueued for forwarding to the single processor. Information from all snoop cache filters assigned to all ports in the snoop filter unit are removed in the case that data corresponding to any one of the memory addresses contained in snoop cache filter is loaded in the cache hierarchy of the processor the snoop cache filter is assigned to.

摘要： A method and apparatus for supporting cache coherency in a multiprocessor computing environment having multiple processing units, each processing unit having a local cache memory associated therewith. A snoop filter device is associated with each processing unit and includes at least one snoop filter primitive implementing filtering method based on usage of stream registers sets and associated stream register comparison logic. From the plurality of stream registers sets, at least one stream register set is active, and at least one stream register set is labeled historic at any point in time. In addition, the snoop filter block is operatively coupled with cache wrap detection logic whereby the content of the active stream register set is switched into a historic stream register set upon the cache wrap condition detection, and the content of at least one active stream register set is reset. Each filter primitive implements stream register comparison logic that determines whether a received snoop request is to be forwarded to the processor or discarded.

摘要： In a massively parallel computing system having a plurality of nodes configured in m multi-dimensions, each node including a computing device, a method for routing packets towards their destination nodes is provided which includes generating at least one of a 2 m plurality of compact bit vectors containing information derived from downstream nodes. A multilevel arbitration process in which downstream information stored in the compact vectors, such as link status information and fullness of downstream buffers, is used to determine a preferred direction and virtual channel for packet transmission. Preferred direction ranges are encoded and virtual channels are selected by examining the plurality of compact bit vectors. This dynamic routing method eliminates the necessity of routing tables, thus enhancing scalability of the switch.
