Dear Pwscf users: I'm using the PWSCF v.3.2.3 to perform geometry optimization. When I set the value of "ecutwfc" larger than 45.5 Ry (including 45.5), the pw.x will stop with "Starting wfc are atomic", I tried to wait for at least about 5 or 6 hours and it still stopped there. When I set "ecutwfc" lower than 45.5 (even 45.49), the pw.x will work well. Many thanks for your help.
