well, as documented in the txt file with the program, setting the affinity in taskmanager is only possible after the process has been launched (which may be too late)... as for 'frontend'.. depends.. the tool does use the setprocessaffinity api's if that's what you mean... but does so by launching the process suspended, setting the affinity, then resuming the process... which is a little bit different than the windows launch -> user alt+tab -> taskmanager -> set affinity approach...
