摘要： A technique for indicating a safe shared resource condition with respect to a disabled thread provides a mechanism for providing a fast indication to other hardware threads that a temporarily disabled thread can no longer impact shared resources, such as shared special-purpose registers and translation look-aside buffers within the processor core. Signals from pipelines within the core indicates whether any of the instructions pending in the pipeline impact the shared resources and if not, then the thread disable status is presented to the other threads via a state change in a thread status register. Upon receiving an indication that a particular hardware thread is to be disabled, control logic halts the dispatch of instructions for the particular hardware thread, and then waits until any indication that a shared resource is impacted by an instruction has cleared. Then the control logic updates the thread status to indicate the thread is disabled.
摘要翻译：用于指示关于被禁用线程的安全共享资源状况的技术提供了一种用于向其他硬件线程提供快速指示的机制，临时禁用的线程不再影响共享资源，例如共享专用寄存器和翻译查找，处理器核心内的缓冲区。来自核心内的流水线的信号表示流水线中的任何待执行的任何指示是否影响共享资源，如果没有，则通过线程状态寄存器中的状态更改将线程禁用状态呈现给其他线程。在接收到特定硬件线程被禁用的指示时，控制逻辑停止对特定硬件线程的指令的分派，然后等待直到由指令影响共享资源的任何指示已经被清除。然后控制逻辑更新线程状态以指示线程被禁用。

摘要： A performance monitoring technique provides task-switch immune operation without requiring storage and retrieval of the performance monitor state when a task switch occurs. When a hypervisor signals that a task is being resumed, it provides an indication, which starts a delay timer. The delay timer is resettable in case a predetermined time period has not elapsed when the next task switch occurs. After the delay timer expires, analysis of the performance monitor measurements is resumed, which prevents an initial state or a state remaining from a previous task from corrupting the performance monitoring results. The performance monitor may be or include an execution trace unit that collects taken branches in a current trace and may use branch prediction success to determine whether to collect a predicted and taken branch instruction in a current trace or to start a new segment when the branch resolves in a non-predicted direction.
摘要翻译：性能监控技术提供任务切换免疫操作，而不需要在发生任务切换时存储和检索性能监视器状态。当管理程序发出任务正在恢复的信号时，它提供指示，启动一个延迟定时器。在发生下一任务切换的情况下，在没有经过预定时间段的情况下，可以将延迟定时器复位。在延迟定时器到期后，恢复对性能监视器测量的分析，这阻止了先前任务的初始状态或状态损坏性能监视结果。性能监视器可以是或包括执行跟踪单元，其在当前跟踪中收集所采取的分支，并且可以使用分支预测成功来确定是否在当前跟踪中收集预测和采取的分支指令，或者当分支解析时启动新分段处于非预测方向。

摘要： Apparatus and program product for assigning or confirming multiple address identifications to a single channel adapter. A server contains multiple partitions connected to a single channel adapter which is used to send data and commands to a fabric. A request is sent to the fabric on behalf of each of the partitions, and the fabric assigns or confirms and returns to the adapter, an address identification associated to each partition on whose behalf the request was sent. The assigned or confirmed address is used to communicate between controllers connected to the fabric and the associated partition through the same channel adapter.

摘要： A method of data processing includes a processor of a data processing system executing a controlling thread of a program and detecting occurrence of a particular asynchronous event during execution of the controlling thread of the program. In response to occurrence of the particular asynchronous event during execution of the controlling thread of the program, the processor initiates execution of an assist thread of the program such that the processor simultaneously executes the assist thread and controlling thread of the program.

摘要： An exemplary embodiment of the invention relates to a method, system, and storage medium for resolving contention issues by a channel in a fibre optic switch environment that occur during channel program execution. The method comprises a channel receiving a status packet indicating a device is no longer busy. The method also includes specifying whether the channel intends to re-initiate a channel program that previously resulted in the device busy status. If the channel does not intend to re-initiate the channel program, a first combination of bits in a re-initiate field of a status-acceptance packet are set which indicate that the channel will take no further action. If the channel intends to re-initiate the channel program, a second combination of bits in the re-initiate field of the status-acceptance packet are set, indicating that the channel will re-initiate the channel program. The method further includes transmitting the status-acceptance packet to a control unit. The invention also includes a system and a storage medium.
