Use the Merge Runs dialog box to select one or more runs to merge with another run (labeled as the Current run in the Merge Runs dialog box), to create a new dataset.
Merging datasets is especially useful when you want to tune the performance of code shared by two or more programs. By running the programs and merging their datasets, you can verify that the code changes benefit each program equally, and do not cause one program's performance to improve while another program's performance regresses.
These are the main controls in the dialog box:
Note:
§ For the merge results to be meaningful, merge runs that use the same instrumentation mode, measurement type and timing methods for each module. For example, if the current run measured the executable at line level and used elapsed time to time blocking and waiting functions, the runs you merge with it should have used the same measurement type and timing method.
