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 computer system includes a virtual machine (VM) configuration with one or more cores. Each core is enabled to operate in a single thread (ST) mode or a multithreading (MT) mode. The ST mode consists of a single thread and the MT mode consists of a plurality of threads on shared resources of a respective core. The computer system includes a core-oriented system control area (COSCA) having a common area representing all of the cores of the VM configuration and separate core description areas for each of the cores in the VM configuration. Each core description area indicates a location of one or more thread description areas each representing a thread within the respective core, and each thread description area indicates a location of a state description of the respective thread.

Abstract: Selected installed function of a multi-function instruction is hidden such that even though a processor is capable of performing the hidden installed function, the availability of the hidden function is hidden such that responsive to the multi- function instruction querying the availability of functions, only functions not hidden are reported as installed.

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: 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: 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.
