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: Eine Einrichtung zum Beenden von bedingten Befehlen wird bereitgestellt, die ermöglicht, dass ein Ausführen eines Befehls verzögert wird. Beim Ausführen des Maschinenbefehls wird ein Operand erhalten, und es wird ermittelt, ob der Operand eine vorgegebene Beziehung in Bezug auf einen Wert hat. Auf der Grundlage des Feststellens, dass der Operand die vorgegebene Beziehung in Bezug auf einen Wert nicht hat, werden Erhalten und Ermitteln wiederholt. Auf der Grundlage des Feststellens, dass der Operand die vorgegebene Beziehung in Bezug auf einen Wert hat, findet das Ausführen des Befehls statt. Erhalten des Operanden, Ermitteln, ob der Operand die vorgegebene Beziehung hat, Wiederholen von Erhalten und Ermitteln auf der Grundlage des Feststellens, dass der Operand die vorgegebene Beziehung in Bezug auf den Wert nicht hat, und Ausführen des Befehls auf der Grundlage des Feststellens, dass der Operand die vorgegebene Beziehung in Bezug auf den Wert hat, werden als Teil eines einzigen Befehls ausgeführt, der einen Operationscode enthält.

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: 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: A method includes processing an application by a host including one or more processors and distributing at least a portion of the application to an accelerator for execution. The method includes instructing the accelerator to create a buffer on the accelerator and instructing the accelerator to execute the portion of the application, wherein the accelerator writes data to the buffer. The method also includes instructing the accelerator to transmit the data in the buffer to the host before the application requests the data in the buffer. The accelerator aggregates the data in the buffer before transmitting the data to the host based upon one or more runtime conditions in the host.

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.
