    摘要: 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.

    摘要: The amount of host real storage provided to a large guest storage buffer is controlled. This control is transparent to the guest that owns the buffer and is executing an asynchronous process to update the buffer. The control uses one or more indicators to determine when additional host real storage is to be provided.

    摘要: A method, system, and computer program product for maintaining reliability in a computer system. In an example embodiment, the method includes performing a first data computation by a first set of processors, the first set of processors having a first computer processor architecture. The method continues by performing a second data computation by a second processor coupled to the first set of processors, the second processor having a second computer processor architecture, the first computer processor architecture being different than the second computer processor architecture. Finally, the method includes dynamically allocating computational resources of the first set of processors and the second processor based on at least one metric while the first set of processors and the second processor are in operation such that the accuracy and processing speed of the first data computation and the second data computation are optimized.

    摘要: In a logically partitioned host computer system comprising host processors (host CPUs), a facility and instruction for discovering topology of one or more guest processors (guest CPUs) of a guest configuration comprises a guest processor of the guest configuration fetching and executing a STORE SYSTEM INFORMATION instruction that obtains topology information of the computer configuration. The topology information comprising nesting information of processors of the configuration and the degree of dedication a host processor provides to a corresponding guest processor. The information is preferably stored in a single table in memory.
