Hello all,
when starting vasp with this INCAR:
"System = Pt(1ML)/Co(3ML)/Pt(111)(Large)

NWRITE = 3
LREAL = Auto

ISPIN = 2
IALGO = 48
ISMEAR = 2
SIGMA = 0.2
NPAR = 1

NSW = 0

RWIGS = 1.455 1.302

ENMAX = 348.3935"

The system responds

" Error reading item 'IMAGES' from file INCAR.", although IMAGES is not set.
Has anyone got a solution?
Thanks in Advance

this is usually not a specific error for the IMAGES tag. IMAGES is the first tag read from INCAR in the parallel version of VASP, so usually this errror message rather shows up if the INCAR file itself is missing in the working directory of the job or is otherwise corrupted.

You might want to compile vasp with the new version of mpich2 (mpich2.1.3.2.p1) which uses hydra as a default resource manager. There is no need to invoke mpd or mpdboot anymore. This might solve the reading error of INCAR by the calculating remote nodes. To run the new mpich2:

mpiexec.hydra -f <yournodefile> -n 128 mpivasp > vasp.out

you will need to put the global var (the -f) first before the local var (the -n).
