摘要： A low latency memory system access is provided in association with a weakly-ordered multiprocessor system. Each processor in the multiprocessor shares resources, and each shared resource has an associated lock within a locking device that provides support for synchronization between the multiple processors in the multiprocessor and the orderly sharing of the resources. A processor only has permission to access a resource when it owns the lock associated with that resource, and an attempt by a processor to own a lock requires only a single load operation, rather than a traditional atomic load followed by store, such that the processor only performs a read operation and the hardware locking device performs a subsequent write operation rather than the processor. A simple prefetching for non-contiguous data structures is also disclosed. A memory line is redefined so that in addition to the normal physical memory data, every line includes a pointer that is large enough to point to any other line in the memory, wherein the pointers to determine which memory line to prefetch rather than some other predictive algorithm. This enables hardware to effectively prefetch memory access patterns that are non-contiguous, but repetitive.

摘要： A method and apparatus for detecting a cache wrap condition in a computing environment having a processor and a cache. A cache wrap condition is detected when the entire contents of a cache have been replaced, relative to a particular starting state. A set-associative cache is considered to have wrapped when all of the sets within the cache have been replaced. The starting point for cache wrap detection is the state of the cache sets at the time of the previous cache wrap. The method and apparatus is preferably implemented in a snoop filter having filter mechanisms that rely upon detecting the cache wrap condition. These snoop filter mechanisms requiring this information are operatively coupled with cache wrap detection logic adapted to detect the cache wrap event, and perform an indication step to the snoop filter mechanisms. In the various embodiments, cache wrap detection logic is implemented using registers and comparators, loadable counters, or a scoreboard data structure.

摘要： The present invention concerns methods and apparatus for performing fault isolation in multiple node computing systems using commutative error detection values—for example, checksums—to identify and to isolate faulty nodes. In the present invention nodes forming the multiple node computing system are networked together and during program execution communicate with one another by transmitting information through the network. When information associated with a reproducible portion of a computer program is injected into the network by a node, a commutative error detection value is calculated and stored in commutative error detection apparatus associated with the node. At intervals, node fault detection apparatus associated with the multiple node computer system retrieve commutative error detection values saved in the commutative error detection apparatus associated with the node and stores them in memory. When the computer program is executed again by the multiple node computer system, new commutative error detection values are created; the node fault detection apparatus retrieves them and stores them in memory. The node fault detection apparatus identifies faulty nodes by comparing commutative error detection values associated with reproducible portions of the application program generated by a particular node from different runs of the application program. Differences in commutative error detection values indicate that the node may be faulty.
