The standard output of VASP has several sections. Some examples for each are given below:

No of nodes, MPI ranks, OpenMP threads, and parallelization

The first output details rank, threading, and parallelization information. E.g with OpenMP threading:

running   16 mpi-ranks, with    4 threads/rank, on    1 nodes
distrk:  each k-point on    4 cores,    4 groups
distr:  one band on    1 cores,    4 groups

or without OpenMP threading, but NCORE set:

running   16 mpi-ranks, with    1 threads/rank, on    1 nodes
distrk:  each k-point on    4 cores,    4 groups
distr:  one band on    2 cores,    2 groups

Version number, build date, and executable type

Note that both the standard and the noncollinear version print out "complex", while the gamma-only version prints "gamma-only": vasp_std and vasp_ncl:

vasp.6.4.3 19Mar24 (build Sep 03 2024 17:30:01) complex

vasp_gam:

vasp.6.5.0 16Dec24 (build Feb 28 2025 14:30:48) gamma-only

Structure information

POSCAR found type information on POSCAR CoSiTi
POSCAR found :  3 types and       4 ions

ScaLAPACK

This line is present if VASP is installed with ScaLAPACK, which is a requirement for VASP 6.

scaLAPACK will be used

LDA part of correlation

The following line prints the implementation selected for the LDA XC energy. E.g.:

LDA part: xc-table for (Slater+PW92), standard interpolation

or

LDA part: xc-table for (Slater(with rela. corr.)+CA(PZ))
, standard interpolation

Reading the WAVECAR header

If a WAVECAR is present, the header is read now

found WAVECAR, reading the header

If the no of k-points changed, a warning is printed here

number of k-points has changed, file:    20 present:     8
trying to continue reading WAVECAR, but it might fail

Input file check

If the input files POSCAR, INCAR, and KPOINTS are consistent, the following line is printed

POSCAR, INCAR and KPOINTS ok, starting setup
