Latest Patents

Durgam Vahia holds a patent for a "Shared memory multiprocessor memory model verification system and method." This system and method are designed to verify a memory consistency model for shared memory multiprocessor computer systems. It generates random instructions to run on the processors, saves the results of these instructions, and analyzes the results to detect any memory subsystem errors. If the results fall outside the space of possible outcomes consistent with the memory consistency model, the system identifies these discrepancies. A precedence relationship of the results is established by uniquely identifying results of a store location, allowing for the association of a read result value to the instruction that created it. The system utilizes a precedence graph with static, direct, and derived edges to identify errors, particularly when a cycle is detected that indicates results inconsistent with memory consistency model rules.
