DECOUPLING DYNAMIC PROGRAM ANALYSIS FROM EXECUTION ACROSS HETEROGENEOUS SYSTEMS

摘要

Dynamic program analysis is decoupled from execution in virtual computer environments so that program analysis can be performed on a running computer program without affecting or perturbing the workload of the system on which the program is executing. Decoupled dynamic program analysis is enabled by separating execution and analysis into two tasks: (1) recording, where system execution is recorded with minimal interference, and (2) analysis, where the execution is replayed and analyzed. Recording and analysis are carried out on heterogeneous systems so that they can be separately optimized.
