Abstract
A method may include obtaining a concurrent application including processes, each including operations, and obtaining an initial hybrid timestamp for an initial operation of a process. The initial hybrid timestamp may include a vector list timestamp including vector clocks, each including a clock value for each of the processes. The method may further include determining a synchronization category for a next operation of the process, and in response to the synchronization category indicating that the next operation does not require inter-process synchronization, generating a next hybrid timestamp for the next operation. The next hybrid timestamp may include a differential timestamp relative to the initial hybrid timestamp.
