[Pw_forum] a question about a calculation on a relatively large system

Dear all,
Thanks a lot for all the expert advice! I tried cpv on my system and it
worked fine!
Well, I am still curious why pw.x did not work. It would be useful
to identify whether
or not it is due to the system size.
A couple of things that I have tested:
1. Using "restart_mode='restart' ", the run stopped at the same point.
2. Using smaller ecutwfc did not help either.
3. Runing the job on an SGI and a PC cluster, no difference found
In this case, I am not sure what to try next. The pw.x input file is as
follows (sorry about
its length). If someone can have a quick test run on it, I would really
appreciate it.
