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: Bereitgestellt wird eine Verzögerungseinrichtung, in der eine Programmausführung verzögert werden kann, bis ein vordefiniertes Ereignis eintritt, z. B. bis ein Vergleich von Arbeitsspeicherpositionen eine wahre Bedingung ergibt, eine Zeitüberschreitung erreicht wird, eine Unterbrechung ausgesetzt wird oder eine andere Bedingung gegeben ist. Die Verzögerungseinrichtung beinhaltet einen oder mehrere „Compare and Delay”-Maschinenbefehle, mit denen eine Ausführung verzögert wird. Der eine oder die mehreren „Compare and Delay”-Befehle können einen 32-Bit-„Compare and Delay”-Befehl (CAD-Befehl) und einen 64-Bit-„Compare and Delay”-Befehl (CADG-Befehl) beinhalten.

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: Machine instructions, referred to herein as a long Convert from Zoned instruction (CDZT) and extended Convert from Zoned instruction (CXZT), are provided that read EBCDIC or ASCII data from memory, convert it to the appropriate decimal floating point format, and write it to a target floating point register or floating point register pair. Further, machine instructions, referred to herein as a long Convert to Zoned instruction (CZDT) and extended Convert to Zoned instruction (CZXT), are provided that convert a decimal floating point (DFP) operand in a source floating point register or floating point register pair to EBCDIC or ASCII data and store it to a target memory location.
