Dear MyTrinh,
the outdir variable, or at least the wfcdir variable, must point to the
local scratch directory: their default value is $HOME/tmp.

You can also use disk_io='none' to completely prevent the output of
wavefunctions to disk. It may see a drastic solution, but if you don't
have the possibility to restart an interrupted job on the same nodes it
does not really make much difference.

best regards
