21. This slows down the program execution . 22. With stabilized rates, gains or losses in operations may occur as a result of variations in program execution . 23. "' Dynamic compilation "'is a process used by some programming language implementations to gain performance during program execution . 24. This resulted in further overlapping, thus higher program execution speed than might be expected from the slow clock rate. 25. By tracking a call graph, it may be possible to detect anomalies of program execution or code injection attacks. 26. During the execution of certain programs there are places where the program execution flow can continue in several ways. 27. The timer interrupt STXIT provided a mechanism for sampling program execution and was used by various legacy performance analyzers. 28. If the result is nonzero then program execution jumps relative to the address of the PC plus the displacement. 29. Concurrent garbage collectors do not stop program execution at all, except perhaps briefly when the program's execution stack is scanned. 30. ClusterSim, on the other hand uses a hybrid higher-level modeling system independent of the programming language used for program execution .
