Abstract: Se provee un programa (por ejemplo, un sistema operativo) una advertencia de que tiene un periodo de gracia en el cual se puede ejecutar una función, tal como limpieza (por ejemplo, completa, detener y/o hacer mover una unidad despachable). El programa es advertido, en un ejemplo, que está perdiendo acceso a sus recursos compartidos. Por ejemplo, en un medio ambiente virtual, un programa invitado es advertido que está a punto de perder sus recursos de unidad de procesamiento central y por consiguiente, va a efectuar una posición tal como limpieza.

Abstract: A program (e.g., an operating system) is provided a warning that it has a grace period in which to perform a function, such as cleanup (e.g., complete, stop and/or move a dispatchable unit). The program is being warned, in one example, that it is losing access to its shared resources. For instance, in a virtual environment, a guest program is warned that it is about to lose its central processing unit resources, and therefore, it is to perform a function, such as cleanup.

Abstract: Various address translation formats are available for use in obtaining system memory addresses for use by requestors, such as adapter functions, in accessing system memory. The particular address translation format to be used by a given requestor is pre-registered in a device table entry associated with that requestor.

Abstract: Las modalidades se refieren a subprocesamiento múltiple en una computadora. Un aspecto es una computadora que incluye una configuración que tiene un núcleo que incluye subprocesos físicos y es operable en modos de subprocesamiento individual (ST) y subprocesamiento múltiple (MT). La computadora también incluye un programa anfitrión configurado para ejecutarse en el modo ST en el núcleo para emitir una instrucción de inicio de ejecución virtual (inicio de VE) para distribuir una entidad invitada que incluye una máquina virtual (VM) invitada. La instrucción de inicio de VE se ejecuta por el núcleo e incluye obtener una descripción de estado, que tiene un estado de invitado, desde una ubicación especificada por la instrucción de inicio de VE. La ejecución incluye determinar, con base en el estado de invitado, si la entidad invitada incluye un subproceso invitado individual o múltiples subprocesos invitados, e iniciar los subprocesos invitados en el modo MT o modo ST con base en el estado de invitado y una determinación de si la entidad invitada incluye un subproceso invitado individual o múltiples subprocesos invitados.

Abstract: THREAD CONTEXT RESTORATION IN A MULTITHREADING COMPUTER SYSTEM Amultithreading computer system includesa 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.

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.
