Latest Patents

One of Erez Petrank's latest patents is titled "Optimistic Object Relocation." This innovation addresses the challenges associated with relocating objects in memory while ensuring that concurrent threads can still write to the object during the process. The technique allows for non-blocking relocation, which monitors memory accesses and deallocates the destination address if a write is detected during the relocation. This method not only improves the efficiency of object relocation but also minimizes synchronization issues.

Another significant patent is "Incremental Lock-Free Stack Scanning for Garbage Collection." This method introduces a concurrent, incremental, and lock-free approach to stack scanning for garbage collectors. By utilizing a summary table and return barriers, the technique allows for high responsiveness and imposes negligible overhead on program execution. It is compatible with existing concurrent collectors and supports fine-synchronization in programming languages such as C#.
