摘要： Differential configuration update commands can be communicated and applied quickly and efficiently to active zone sets and zone set libraries, without requiring propagation of entire zone sets through a fabric of a SAN. Furthermore, the commands can be applied quickly to support dynamic configuration updates. Ordered differential configuration update commands can be applied to ordered zone set data structures to minimize update instruction communication requirements and optimize configuration update operations. In addition, differential configuration update commands can be applied to active zone set data structures (e.g., in an active zone set or a zone set library) to optimize configuration update operations.
摘要翻译：可以将差异配置更新命令快速有效地传达和应用于活动区域集和区域集库，而不需要通过SAN的结构传播整个区域集。此外，可以快速应用这些命令来支持动态配置更新。有序的差分配置更新命令可以应用于有序区域集数据结构，以最小化更新指令通信要求并优化配置更新操作。此外，差分配置更新命令可以应用于活动区域集数据结构（例如，在活动区域集合或区域集库中）以优化配置更新操作。

摘要： Intelligent services are provided in a storage network using intelligent service modules that can be cabled to a switch external to the switch chassis and yet be managed as part of the switch's logical domain. Data and management communications between the intelligent service module and the core switch are provided through a “soft-backplane” implemented using in-band communications through cabling attached between the switch and the intelligent service module rather than through hardwired backplane within the chassis. Management communications from management software is directed to the switch, which handles the management functions relating to the intelligent service module or forwards the management requests to the intelligent service module for processing.

摘要： A processor reduces wasted cycle time resulting from stalling and idling, and increases the proportion of execution time, by supporting and implementing both vertical multithreading and horizontal multithreading. Vertical multithreading permits overlapping or “hiding” of cache miss wait times. In vertical multithreading, multiple hardware threads share the same processor pipeline. A hardware thread is typically a process, a lightweight process, a native thread, or the like in an operating system that supports multithreading. Horizontal multithreading increases parallelism within the processor circuit structure, for example within a single integrated circuit die that makes up a single-chip processor. To further increase system parallelism in some processor embodiments, multiple processor cores are formed in a single die. Advances in on-chip multiprocessor horizontal threading are gained as processor core sizes are reduced through technological advancements.

摘要： A memory cache method and apparatus with two memory execution pipelines, each having a translation lookaside buffer (TLB). Memory instructions are executed in the first pipeline (324) by searching a data cache (310) and a prefetch cache (320). A large data TLB (330) provides memory for storing address translations for the first pipeline (324) A second pipeline (328) executes memory instructions by accessing the prefetch cache (320). A second micro-TLB (340) is associated with the second pipeline (328). It is loaded in anticipation of data that will be referenced by the second pipeline (328). A history file (360) is also provided to retain information on previous instructions to aid in deciding when to prefetch data. Prefetch logic (370) determines when to prefetch data, and steering logic (380) routes certain instructions to the second pipeline (328) to increase system performance.

摘要： A scalable solution to managing fairness in a congested hierarchical switched system is disclosed. The solution comprises a means for managing fairness during congestion in a hierarchical switched system comprising a first level arbitration system and a second level arbitration system of a stage. The first level arbitration system comprises a plurality of arbitration segments that arbitrate between information flows received from at least one ingress point based upon weights associated with those information flows (or the ingress points). Each arbitration segment determines an aggregate weight from each active ingress point providing the information flows to the segment and forwards a selected information flow along with the aggregate weight (in-band or out-of-band) to the second level arbitration system. The second level arbitration system then arbitrates between information flows received from the arbitration segments of the first level arbitration system based upon the aggregate weights received along with those information flows. The second level arbitration system then forwards a selected information flow to an egress point of the stage. The stage may, for example, comprise a portion of a switch, a switch, or a switch network.

摘要： A method and apparatus for scheduling instructions to provide adequate prefetch latency is disclosed during compilation of a program code in to a program. The prefetch scheduler component of the present invention selects a memory operation within the program code as a “martyr load” and removes the prefetch associated with the martyr load, if any. The prefetch scheduler takes advantage of the latency associated with the martyr load to schedule prefetches for memory operations which follow the martyr load. The prefetches are scheduled “behind” (i.e., prior to) the martyr load to allow the prefetches to complete before the associated memory operations are carried out. The prefetch schedule component continues this process throughout the program code to optimize prefetch scheduling and overall program operation.
