The deciding includes comparing a bit value(s) of one or more required components of the previous storage key to respective predefined allowed stale value(s) for the required component(s), and leaving the previous storage key in local processor cache if the bit value(s) of the required component(s) in the previous storage key equals the respective predefined allowed stale value(s) for the required component(s). By selectively leaving the previous storage key in local processor cache, interprocessor communication pursuant to processing of the request to update the previous storage key to the new storage key is minimized."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Reducing interprocessor communications pursuant to updating of a storage key","description":"Processing within a multiprocessor computer system is facilitated by: deciding by a processor, pursuant to processing of a request to update a previous storage key to a new storage key, whether to pur","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8521964","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
