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: Un sistema de computadora incluye una configuración con un núcleo configurable entre un modo de subprocesamiento individual (ST) y un modo de subprocesamiento múltiple (MT). El modo ST dirige un subproceso primario y el modo MT dirige el subproceso primario y uno o más subprocesos secundarios en recursos compartidos del núcleo. Se configura un servicio de subprocesamiento múltiple para controlar la utilización de la configuración para llevar a cabo un método que incluye acceder al subproceso primario en el modo ST utilizando un valor de dirección de núcleo y conmutar del modo ST al modo MT. Se accede al subproceso primario o uno del uno o más subprocesos secundarios en el modo MT utilizando un valor de dirección expandida, en donde el valor de dirección expandida incluye el valor de dirección de núcleo concatenado con un valor de dirección de subproceso.

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: Embodiments relate to dynamic enablement of multithreading. According to an aspect, a computer system includes 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. The computer system also includes a multithreading facility configured to control the configuration to perform a method. The method includes executing in the primary thread in the ST mode, an MT mode setting instruction. A number of threads requested is obtained from a location specified by the MT mode setting instruction. Based on determining that the number of threads requested indicates multiple threads, the MT mode is enabled to execute the multiple threads including the primary thread and the one or more secondary threads.

Abstract: fornecimento por um programa para outro programa de acesso a uma facilidade de faixa de aviso. é fornecido a um programa (por exemplo, um sistema operacional) um aviso de que ele tem um período de tolerância para executar uma função, tal como limpeza (por exemplo, finalizar, parar e/ou mover uma unidade despachável). o programa é notificado, em um exemplo, de que está perdendo acesso aos recursos compartilhados. por exemplo, em um ambiente virtual, um programa convidado é notificado que está prestes a perder os recursos da unidade de processamento central e, portanto, deve executar uma função, tal como limpeza.

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.
