Methods and apparatus to detect a macroscopic transaction boundary in a program

摘要

Methods and apparatus are disclosed to detect a macroscopic transaction boundary in a program workload. An example method includes identifying a transactional entropy value associated with macroscopic transactions of the workload; developing a trace of a program; identifying a sequence of program states from the trace; determining program state entropy values associated with the program states identified in the sequence; and identifying a program state in the sequence of program states and associated with a program state entropy value that is substantially equal to the transactional entropy value as a macroscopic transaction boundary.
