MUMBAI, India, Nov. 2 -- Intellectual Property India has published a patent application (202641126814 A) filed by Vellore Institute Of Technology on October 24, 2026, for Lock-Importance And Dependency-Aware Cooperative Cpu Scheduling System For Multicore Operating Systems.
Inventors include Dharmendra Singh Rajput; and Saharsh Ojha.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: ABSTRACT LOCK-IMPORTANCE AND DEPENDENCY-AWARE COOPERATIVE CPU SCHEDULING SYSTEM FOR MULTICORE OPERATING SYSTEMS A lock-importance and dependency-aware cooperative CPU scheduling system (100) for multicore operating systems comprises a multicore processor (10) having a plurality of CPU cores and a memory (20) coupled to the multicore processor (10). The system (100) comprises a runtime dependency tree module (110) configured to construct a directed acyclic graph representing parent-child dependency relationships among concurrent threads, a runtime dependency analyzer (120) configured to evaluate dependency depth, descendant count, and dependency hierarchy, a dynamic lock importance engine (130) configured to compute a lock importance value for each lock-holding thread, a multi-core coordination engine (140) configured to monitor processor utilization and coordinate thread placement, a thread classification engine (150) configured to categorize runnable threads into execution classes, a system progress decision engine (160) configured to compute a system progress score and select an execution candidate having a highest system progress score, and a runtime execution engine (170) configured to execute the selected execution candidate and update runtime state information.
