[Pw_forum] PW is frozen

Thanks for your reply. I will try the new version of espresso.
But I did not use k parallelization. I use default parallelization (which is with npool=1, if I remember correctly).

Best Regards

your input works for me on 6 processors (more exactly, 6 processes on 2 processors), with slightly different pseudopotentials. V.5.0 may run into strange problems on some machines with k-point parallelization (details in the Doc/release-notes file).
If this is not your case, it is hard to say what the problem can be without the possibility to make a few tests and to see what is really happening and under which exact conditions. Apart from trying a more recent version, you might consider a poor-man (or poor-woman) debugging by inserting print statements in the main program until you figure out where it hangs
