The first GPU maintains a page table of system memory addresses or frame buffer addresses allocated to and accessed by the source guest VM during a session, including an indication of whether the data was modified. Based on the page table information, the processing system identifies and transfers only the modified pages from the source guest VM to the destination guest VM, thereby reducing the time and bandwidth used for migration."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Targeted page migration for guest virtual machine","description":"A processing system identifies a subset of pages of memory allocated to a source guest virtual machine (VM) running at a first graphics processing unit (GPU) that were modified by the source guest VM ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11256530","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.
