Generally the present invention relates to a software algorithm that simplifies and significantly speeds the management of cache coherence in a message passing parallel computer, and to hardware apparatus that assists this cache coherence algorithm.

The method comprises: generating a synchronized set of enable signals in correspondence with one or more IC sub-units for starting operation of one or more IC sub-units according to a determined timing configuration; counting, in response to one signal of the synchronized set of enable signals, a number of main processor IC clock cycles; and, upon attaining a desired clock cycle number, generating a stop signal for each unique frequency clock domain to synchronously stop a functional clock for each respective frequency clock domain; and, upon synchronously stopping all on-chip functional clocks on all frequency clock domains in a deterministic fashion, scanning out data values at a desired IC chip state. The apparatus and methodology enables construction of a cycle-by-cycle view of any part of the state of a running IC chip, using a combination of on-chip circuitry and software.

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： An apparatus for implementing snooping cache coherence that locally reduces the number of snoop requests presented to each cache in a multiprocessor system. A snoop filter device associated with a single processor includes one or more “scoreboard” data structures that make snoop determinations, i.e., for each snoop request from another processor, to determine if a request is to be forwarded to the processor or, discarded. At least one scoreboard is active, and at least one scoreboard is determined to be historic at any point in time. A snoop determination of the queue indicates that an entry may be in the cache, but does not indicate its actual residence status. In addition, the snoop filter block implementing scoreboard data structures is operatively coupled with a cache wrap detection logic means whereby, upon detection of a cache wrap condition, the content of the active scoreboard is copied into a historic scoreboard and the content of at least one active scoreboard is reset.

摘要： A novel massively parallel supercomputer of petaOPS-scale includes node architectures based upon System-On-a-Chip technology, where each processing node comprises a single Application Specific Integrated Circuit (ASIC) having up to four processing elements. The ASIC nodes are interconnected by multiple independent networks that optimally maximize the throughput of packet communications between nodes with minimal latency. The multiple networks may include three high-speed networks for parallel algorithm message passing including a Torus, collective network, and a Global Asynchronous network that provides global barrier and notification functions. These multiple independent networks may be collaboratively or independently utilized according to the needs or phases of an algorithm for optimizing algorithm processing performance. Novel use of a DMA engine is provided to facilitate message passing among the nodes without the expenditure of processing resources at the node.

摘要： An apparatus and method for tracking coherence event signals transmitted in a multiprocessor system. The apparatus comprises a coherence logic unit, each unit having a plurality of queue structures with each queue structure associated with a respective sender of event signals transmitted in the system. A timing circuit associated with a queue structure controls enqueuing and dequeuing of received coherence event signals, and, a counter tracks a number of coherence event signals remaining enqueued in the queue structure and dequeued since receipt of a timestamp signal. A counter mechanism generates an output signal indicating that all of the coherence event signals present in the queue structure at the time of receipt of the timestamp signal have been dequeued. In one embodiment, the timestamp signal is asserted at the start of a memory synchronization operation and, the output signal indicates that all coherence events present when the timestamp signal was asserted have completed. This signal can then be used as part of the completion condition for the memory synchronization operation.
