During a first recorded execution of the virtual machine application program, a record is created and stored in a computer that indicates the order in which threads acquire the application-level mutex. In a subsequent replay execution of the virtual machine application program from the recording, threads of the virtual machine application program are managed to ensure that the application-level mutex is acquired by threads in the same order indicated in the record such that any race conditions that occurred during the recorded execution as a result of executing application code are reproduced during the subsequent replay execution thereby aiding application development personnel in identifying and isolating program errors and bugs related to race conditions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ensuring deterministic thread context switching in virtual machine applications","description":"Techniques for ensuring deterministic thread context switching in a virtual machine application program include, in one embodiment, providing a single application-level mutex that threads of the execu","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8499299","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.
