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: Se provee a un programa (por ejemplo, un sistema operativo) una advertencia que tiene un período de gracia en el cual puede efectuar una función, tal como limpieza (por ejemplo, completar, detener y/o hacer mover una unidad despachable). El programa es advertido, en un ejemplo, que está perdiendo acceso a sus recursos compartidos. 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 función 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: Embodiments relate to dynamic enablement of multithreading. According to an aspect, a computer-implemented method for dynamic enablement of multithreading in a configuration is provided. The configuration includes a core configurable between a single thread (ST) mode and a multithreading (MT) mode, where 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 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: Un sistema informático, que comprende: una configuración (102) que comprende un núcleo configurable entre un modo de subproceso único (ST) y un modo de subprocesamiento múltiple (MT), el modo ST que se dirige a un subproceso primario y el modo MT que se dirige al subproceso primario y a uno o más subprocesos secundarios sobre recursos compartidos del núcleo; y una facilidad de subprocesamiento múltiple (103) configurada para controlar la utilización de la configuración, en donde la facilidad de subprocesamiento múltiple está adaptada para: acceder al subproceso primario en el modo ST usando un valor de dirección de núcleo; conmutar del modo ST al modo MT; y acceder al subproceso primario o a uno del uno o más subprocesos secundarios en el modo MT, y caracterizado por que la facilidad de subprocesamiento múltiple está adaptada para acceder al subproceso primario o a uno del uno o más subprocesos secundarios en el modo MT usando un valor de dirección expandido, comprendiendo el valor de dirección expandido el valor de dirección de núcleo concatenado con un valor de dirección de subproceso.

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.
