Hi everyone,

I am now trying to run a pbe0 calculation with espresso, but when I restart the calculation, it seems just calculate from the beginning. 

Here is my input file for the second run:

The following is the Fermi energy from first run:

     the Fermi energy is    19.8843 ev
     the Fermi energy is    19.4748 ev
     the Fermi energy is    19.4581 ev
     the Fermi energy is    19.4616 ev
     the Fermi energy is    19.7605 ev
     the Fermi energy is    19.4942 ev
     the Fermi energy is    19.4951 ev
     the Fermi energy is    19.4955 ev
     the Fermi energy is    19.4957 ev
     the Fermi energy is    19.4958 ev

Here are the fermi energy from the second restart run:

     the Fermi energy is    19.8845 ev
     the Fermi energy is    19.4748 ev
     the Fermi energy is    19.4581 ev
     the Fermi energy is    19.4616 ev
     the Fermi energy is    19.7604 ev
     the Fermi energy is    19.4944 ev

>From the fermi energy, it looks like the job is just start from the beginning. Also the accuracy looks the same for these two runs...

Any reply will be helpful, thank you very much.
