US Patent 10552408 Automatic linearizability checking of operations on concurrent data structures

A method may include executing operation types on a concurrent data structure to obtain executed operations. Each executed operation may cause a transition from a preceding state to a subsequent state. The method may further include recording each executed operation to obtain recorded operations, and assembling a concurrent history from the recorded operations. The concurrent history may include a subset of the recorded operations, and the concurrent history may impose overlapping and non-overlapping relationships on the subset of recorded operations. The method may further include checking whether the concurrent history has an equivalent linearization including a total sequential ordering of the subset of recorded operations, and reporting an error when the concurrent history has no equivalent linearization.
