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.

Abstract: Embodiments relate to address expansion and contraction in a multithreading computer system. According to one aspect, a computer implemented method for address adjustment in a configuration is provided. The configuration includes a core configurable between an ST mode and an 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 primary thread is accessed in the ST mode using a core address value. Switching from the ST mode to the MT mode is performed. The primary thread or one of the one or more secondary threads is accessed in the MT mode using an expanded address value. The expanded address value includes the core address value concatenated with a thread address value.

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 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: Ein Verfahren beinhaltet ein Verarbeiten einer Anwendung durch einen Host mit einem oder mehreren Prozessoren und ein Verteilen mindestens eines Teils der Anwendung zum Verarbeiten an einen Beschleuniger. Das Verfahren beinhaltet ein Anweisen des Beschleunigers, einen Puffer auf dem Beschleuniger zu erstellen, und ein Anweisen des Beschleunigers, den Teil der Anwendung auszuführen, wobei der Beschleuniger Daten in den Puffer schreibt. Das Verfahren beinhaltet außerdem ein Anweisen des Beschleunigers, die Daten an den Host zu senden, bevor die Anwendung die Daten in dem Puffer anfordert. Der Beschleuniger fasst die Daten in dem Puffer vor dem Senden der Daten an den Host auf der Grundlage einer oder mehrerer Laufzeitbedingungen in dem Host zusammen.

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: Various address translation formats are available for use in obtaining system memory addresses for use by requestors in accessing system memory. The particular address translation format to be used by a given requestor, an example of which is an adapter function, is pre-registered in a device table entry associated with that requestor.

Abstract: A method, system, and computer program product for maintaining reliability in a computer system. In an example embodiment, the method includes managing workloads on a first processor with a first processor architecture by an agent process executing on a second processor with a second processor architecture. The method proceeds by activating redundant computation on the second processor by the agent process. The method continues by performing a same computation from a workload of the workloads at least twice. Finally, the method includes comparing results of the same computation. In this embodiment the first processor is coupled the second processor by a network, and the first processor architecture and second processor architecture are different architectures.
