Abstract: uso de uma facilidade de interrupção de faixa de aviso por um programa. a um programa (por exemplo, um sistema operacional) é provido um aviso de que tem um período de carência para executar uma função, tal como limpeza (por exemplo, concluir, interromper e/ou mover uma unidade despachável). o programa está sendo avisado, em um exemplo, de que está perdendo acesso a seus recursos compartilhados. por exemplo, em um ambiente virtual, um programa convidado é avisado de que está próximo de perder seus recursos de unidade de processamento central e, portanto, deve executar uma função, tal como limpeza.

Abstract: The conditions under which adapter interruptions are made pending are controlled. Responsive to an interruption being presented to an operating system, subsequent interruptions are suppressed on all central processing units in the configuration. The operating system processes the interruption, including examining and processing indicators of reported events until the operating system discontinues the suppression. This enables the operating system to control the number of pending interruptions and the number of processors processing those interruptions.

Abstract: A system and method of implementing a modified priority routing of an input/output (I/O) interruption. The system and method determines whether the I/O interruption is pending for a core and whether any of a plurality of guest threads of the core is enabled for guest thread processing of the interruption in accordance with the determining that the I/O interruption is pending. Further, the system and method determines whether at least one of the plurality of guest threads enabled for guest thread processing is in a wait state and, in accordance with the determining that the at least one of the plurality of guest threads enabled for guest thread processing is in the wait state, routes the I/O interruption to a guest thread enabled for guest thread processing and in the wait state.

Abstract: A computing environment facility is provided to extend a hold of a cache line in private (or local) cache exclusively after processing a storage operand request. The facility includes determining whether a storage operand request to a storage location shared by multiple processing units of the computing environment is designated hold. In addition, a determination is made whether a state of the corresponding cache line in private cache used for processing the storage operand request is owned exclusively. Based on determining that the storage operand request is designated hold, and that the state of the corresponding cache line in private cache used for processing the storage operand request is owned exclusively, continuing to hold the corresponding cache line in the private cache exclusively after completing processing of the storage operand request. The continuing to hold may include initiating a counter to facilitate the continuing hold for a desired, set interval.

Abstract: Embodiments relate to multithreading in a computer. An aspect is a computer including a configuration having a core which includes physical threads and is operable in single thread (ST) and multithreading (MT) modes. The computer also includes a host program configured to execute in the ST mode on the core to issue a start-virtual-execution (start-VE) instruction to dispatch a guest entity which includes a guest virtual machine (VM). The start-VE instruction is executed by the core and includes obtaining a state description, having a guest state, from a location specified by the start-VE instruction. The execution includes determining, based on the guest state, whether the guest entity includes a single guest thread or multiple guest threads, and starting the guest threads in the MT mode or ST mode based on the guest state and a determination of whether the guest entity includes a single guest thread or multiple guest threads.

Abstract: Un sistema de computadora incluye una configuración de máquina virtual (VM) con uno o más núcleos. Cada núcleo se hablita para operar en un modo de subprocesamiento individual (ST) o un modo de subprocesamiento múltiple (MT). El modo ST consiste de un subproceso individual y el modo MT consiste de una pluralidad de subprocesos en recursos compartidos de un núcleo respectivo. El sistema de computadora incluye un área de control de sistema orientada al núcleo (COSCA) que tiene un área común que representa todos los núcleos de la configuración de VM y áreas de descripción de núcleo separadas para cada uno de los núcleos en la configuración de VM. Cada área de descripción de núcleo indica una ubicación de una o más áreas de descripción de subproceso cada una que representa un subproceso dentro del núcleo respectivo, y cada área de descripción de subproceso indica una ubicación de una descripción de estado del subproceso respectivo.

Abstract: Embodiments relate to thread context restoration. One aspect is a multithreading computer system including a configuration with a core configurable between a single thread (ST) mode and a multithreading (MT) mode. The ST mode addresses a primary thread and the MT mode addresses the primary thread and one or more secondary threads on shared resources of the core. A multithreading facility is configured to control utilization of the configuration to perform a method including disabling one or more secondary threads based on switching from MT mode to ST mode. A thread context of secondary threads is made unavailable to programs. Based on a last-set program-specified maximum thread-id indicating MT, the thread context is obtained by a) executing a set MT instruction to resume the MT mode, and b) based on being in the resumed MT mode, accessing the thread context.
