[Pw_forum] DOS calculation

[Gabriele Sclauzero]

Maybe your calculation is heavy (many many bands and k-points) and is actually going on (slowly), but you can't see it. To understand if the program is stuck or is just proceeding silently, use verbosity='high' (it will display additional printout each time a k-point has been completed) or look at the time stamps of the .wfc file(s).
