Abstract
Official abstract text for this publication.
Processing within a multiprocessor computer system is facilitated by: setting, in association with invalidate page table entry processing, a storage key at a matching location in central storage of a multiprocessor computer system to a predefined value; and subsequently executing a request to update the storage key to a new storage key, the subsequently executing including determining whether the predefined value is an allowed stale value, and if so, replacing in central storage the storage key of predefined value with the new storage key without requiring purging or updating of the storage key in any local processor cache of the multiprocessor computer system, thus minimizing interprocessor communication pursuant to processing of the request to update the storage key to the new storage key.
First claim
Opening claim text (preview).
What is claimed is: 1. A computer system for facilitating processing of a multiprocessor computer system, the computer system comprising: a memory; and a processor in communications with the memory, wherein the computer system is capable of performing a method, the method comprising: setting, in association with invalidate page table entry processing, an existing storage key at a matching location in central storage of the multiprocessor computer system to a predefined value, w…
