[Pw_forum] Restarting a Job

[Elliot Menkah]

Hello Everyone,
I run a full geometry optimization calculation job on an fcc nickel
(111) surface slab(comprising 96 atoms) which run for 24 hours (Jobs are
allowed to run for only for 24 hrs after which you would have to
re-login to resubmit the job: restart_mode = 'restart' ) without
converging (not a single SCF cycle).

When I restarted the job, I got the error:
--------------------------------------------------------------------------------------------------------------------------------------
  task #        4
      from davcio : error #        10
     error while reading from file "/home/eliot/capping/111-slab    
from davcio : error #        10
     error while reading from file
"/home/eliot/capping/111-slabs/slabs-only/perfect/new/./temp/Ni-111
--------------------------------------------------------------------------------------------------------------------------------------
If I have the charge density file, charge-density.dat, and other files
such as spin-polarization.dat and data-file.xml,
can I successfully restart the job? if so how? Is it to be done
differently from just having to make the value of the 'restart_mode'
variable restart? Such as, 'restart_mode = 'restart'.
