 You can also select a given set of actions defining the environment variable BTL_CONFIG this way:

 Finally, if bench results already exist (the bench*.dat files) then they merges by keeping the best for each matrix size. If you want to overwrite the previous ones you can simply add the "--overwrite" option:
