ReplayEngine replays previously executed commands. ReplayEngine commands are added to the TotalView toolbar. Generally, these commands let you specify which previously executed line in your program you want to examine. These commands are analogous to Next, Step, Out, and Run To. They differ in that they move into the program’s history. That is, entering replay mode is done by pressing a single button. The commands behind these buttons are located on the Instrumentation entry added to the tool bar. (All memory commands have also been moved to Instrumentation.)

Multithreaded codes replay in precisely the same sequence as the threads previously executed. This is especially useful for examining race conditions.

Breakpoints, watchpoints, and some conditional breakpoints can be used when running forward in replay mode.
