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: 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. A multithreading facility is configured to control utilization of the configuration to perform a method that includes accessing the primary thread in the ST mode using a core address value and switching from the ST mode to the MT mode. The primary thread or one of the one or more secondary threads is accessed in the MT mode using an expanded address value, where the expanded address value includes the core address value concatenated with a thread address value.

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.
