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.

Abstract: Transactional execution branch indications are placed into one or more transaction diagnostic blocks when a transaction is aborted. Each branch indication specifies whether a branch was taken, as a result of executing a branch instruction within the transaction. As the transaction executes and a branch instruction is encountered, a branch indication is set in a vector indicating whether the branch was taken. Then, if the transaction aborts, the indicators are stored in one or more transaction diagnostic blocks providing a branch history usable in diagnosing the failure.

Abstract: A program (e.g., an operating system) is provided a warning that it has a grace period in which to perform a function, 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.
