Latest Patents

One of Siwei Lu's latest patents is titled "Hybrid Virtual Thread Context Switching Mechanism." This invention provides a method for managing virtual threads scheduled to run on a virtual machine (VM). It determines whether a virtual thread requires a stack and allocates memory accordingly. If low memory is available, a stack is allocated; if not, unused stacks are copied from low to high memory. The method also includes a mechanism for switching stacks and scheduling virtual threads on carrier threads of the VM.

Another notable patent is "Multiple Level Caching of User Level Thread Stacks for User Level Threads." This invention introduces a multiple-level stack caching system for user-level threads in multithreaded applications. It analyzes the level 1 and level 2 caches to determine their availability and stores user-level thread stacks in the appropriate cache, optimizing memory usage and performance.
