Abstract: PROBLEM TO BE SOLVED: To provide a simple mechanism for previous extraction of a discontinuous data structure such as a very long data structure repeatedly accessed in the same sequence although being discontinuously stored. SOLUTION: This application provides a method for previously extracting a discontinuous data structure which includes steps of pointing discontinuous data structures to incorporate pointers indicative of the access sequence thereof in each data structure; and previously extracting a targeted data structure based on the access sequence shown by the pointers.

Abstract: A method and apparatus for managing coherence between two processors of a tw o processor node of a multi-processor computer system. 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 software algorithm uses the opening and closing of put/get windows to coordinate the activated required to achieve cache coherence. The hardware apparatus may be an extension to the hardware address decode, that creates, in the physical memory address space of the node, an area of virtua l memory that (a) does not actually exist, and (b) is therefore able to respon d instantly to read and write requests from the processing elements.

Abstract: A low latency memory system access is provided in association with a weakly- ordered multiprocessor system(Fig.1). Each processor(12-1, 12-2) in the multiprocessor shares resources, and each shared resource has an associated lock within a locking device(10) that provides support for synchronization between the multiple processors(12-1, 12-2) in the multiprocessor and the orderly sharing of the resources. A processor(12-1, 12-2) only has permissio n to access a resource when it owns the lock associated with that resource, an d an attempt by a processor(12-1, 12-2) to own a l ock requires only a single load operation, rather than a traditional atomic load followed by store, suc h that the processor(12-1, 12-2) only performs a read operation and the hardwa re locking device(10) performs a subsequent write operation rather than the processor(12-1, 12-2).

Abstract: A system and method for enabling high-speed, low-latency global tree communications among processing nodes interconnected according to a tree network structure. The global tree network (100) optimally enables collectiv e reduction operations to be performed during parallel algorithm operations executing in a computer structure having a plurality of the interconnected processing nodes. Router devices (200) are included that interconnect the nodes of the tree via links to facilitate performance of low-latency global processing operations at nodes of the virtual tree and sub-tree structures. The global operations include one or more of: global broadcast operations downstream from a root node (110) to leaf nodes (120) of a virtual tree, global reduction operations upstream from leaf nodes to the root node (110) in the virtual tree, and point-to-point message passing from and any node to th e root node (110) in the virtual tree. One node of the virtual tree network is coupled to and functions as an I/O node for providing I/O functionality with an external system for each node of the virtual tree. The global tree networ k (100) may be configured to provide global barrier and interrupt functionalit y in asynchronous or synchronized manner. Thus, parallel algorithm processing operations, for example,employed in parallel computing systems, may be optimally performed in accordance with certain operating phases of the parallel algorithm operations. When implemented in a massively-parallel supercomputing structure, the global tree network (100) is physically and logically partitionable according to needs of a processing algorithm.
