Latest Patents
Liu's latest patents include innovative methods for enhancing cloud system reliability. One of his patents, titled "Automatically detecting time-of-fault bugs in cloud systems," describes a method implemented by a network element in a distributed system. This method involves tracing the execution of a program to produce a record that indicates the states of shared resources at various times. It identifies vulnerable operations based on the record, particularly when a shared resource is in a flawed state after a node crash. The method also determines the occurrence of a time of fault (TOF) bug through a fault-tolerance mechanism.
Another notable patent is "Automatically detecting distributed concurrency errors in cloud systems." This method focuses on detecting concurrency errors in a distributed cloud computing system by tracing operations that access objects in functions involving inter-process messaging. It applies a set of happens-before rules to analyze these operations, identifying concurrent operations that access a common object and generating a list of potential distributed concurrency errors (DCbugs). The method further prunes the list to remove DCbugs that have only local effects and do not generate run-time errors.
