5.4.4 Installation _best_ — Vasp

cd $SLURM_SUBMIT_DIR mpirun -np 256 /path/to/your/vasp.5.4.4/bin/vasp_std > vasp.out

This step, where you prepare the makefile.include configuration file, is critical and where most issues arise. VASP's build system, introduced in version 5.4.1, relies on this file to define compilers and library paths.

Required for calculations including spin-orbit coupling or non-collinear magnetism. To compile all three versions simultaneously, execute: make all Use code with caution. If you only require the standard parallel version, run: make std Use code with caution.

Intel oneAPI HPC Toolkit (contains ifort or ifx , and icc or icx ) or GCC (gfortran/gcc). MPI Library: Intel MPI or OpenMPI. vasp 5.4.4 installation

: Add -DVASP2WANNIER90 to CPP_OPTIONS and link the libwannier.a library in your makefile.include .

: Always run the parallel binaries using your MPI runner (e.g., mpirun -np 4 vasp_std or srun vasp_std ). Error: Segmentation Fault (SIGSEGV)

GNU builds work, but Intel compilers with MKL typically give 20-30% better performance for VASP. cd $SLURM_SUBMIT_DIR mpirun -np 256 /path/to/your/vasp

I can provide a custom makefile.include based on your answers.

Before beginning, ensure you have the following:

mpirun -np 4 ./vasp_std

Check the OUTCAR and OSZICAR files to ensure the simulation runs without immediate crashes.

GPU-enabled VASP requires careful selection of -gpu=ccXX flags matching your GPU compute capabilities (e.g., cc70 for V100, cc80 for A100).

mkdir ~/vasp_test cd ~/vasp_test cp ../vasp.5.4.4/vasp_std . To compile all three versions simultaneously, execute: make

export OMP_NUM_THREADS=2 mpirun -np 16 vasp_std # 16 MPI ranks, each with 2 OpenMP threads

When you run make , the process is:
