With a total of 4 patents to his name, Lubart's work has had a lasting impact on the efficiency and reliability of multiprocessor systems.
Latest Patents
Lubart's latest patents include a method and apparatus for recovering from a process within the system kernel. This innovative system establishes a passive recovery environment for an operating system kernel. During the binding of the kernel, a cross-reference between an instruction address range and recovery routine address is created. This method ensures that normal process initiation and termination occur without recovery overhead. In the event of a system failure, the failing instruction address is utilized to access recovery routine cross-reference tables, facilitating effective recovery routine processing.
Another significant patent focuses on preventing deadlock in multiprocessor systems executing instructions that require multiple resources. This system detects potential deadlock situations where a multi-resource instruction is blocked from obtaining necessary resources. A global lock is provided that can be held by at most one processor, allowing for conflict detection and resolution. This innovative approach minimizes overhead impact while ensuring that processors can acquire all required resources without encountering deadlock.
