Vasp — 5.4.4 Installation

Here’s a properly structured post suitable for a forum like VASP User Community, ResearchGate, or a Linux HPC mailing list.

• Add new subroutine/function signatures in module files and update interface blocks.
• Maintain consistency with MPI distribution and parallel I/O patterns.

4.2 Build the Standard Libraries

make std

mkdir test_run
cd test_run
cp /path/to/vasp/examples/Si .
mpirun -np 4 /path/to/vasp.5.4.4/bin/vasp_std

• Record compiler versions, MKL/FFT/MPI versions, kernel/OS, and exact makefile.include used (place copy in build logs).
• Save vasp_std binary and run ldd output for later reproducibility and debugging.
• Keep small verification inputs and outputs as regression tests when recompiling.

• Typical VASP builds use MPI for parallelism and OMP_NUM_THREADS=1 at runtime; OpenMP support can be enabled but mixing MPI+OpenMP requires tuning.
