According to user reports, using Intel's 2018 compiler, it is often better to use -O2 instead of -O3 to avoid random convergence issues. Optimize for your CPU architecture, for example: -xCORE-AVX2 or -xCORE-AVX512 .

SYSTEM = example ENCUT = 400 PREC = Normal NCHKW = 2 NSW = 100

You generally need a Fortran compiler (like Intel ifort or GNU gfortran ), numerical libraries such as BLAS , LAPACK , and FFTW , and an MPI library for parallel processing. vasp.5.4.4.tar.gz

The file is the source code archive for the Vienna Ab initio Simulation Package (VASP), version 5.4.4. VASP is a widely used software package for performing ab initio quantum mechanical molecular dynamics (MD) simulations using pseudopotentials and a plane-wave basis set. Released as a stable maintenance update in the VASP 5 series, version 5.4.4 remains a critical computational baseline for materials scientists, physicists, and chemists globally.

Fast Fourier Transform library (Version 3) for transforming electron densities between real and reciprocal space. 3. Step-by-Step Installation and Compilation

VASP 5.4.4 was one of the first versions to play nicely with external libraries for meta-GGAs. If you plan on using SCAN or other advanced functionals, ensure you link the libxc library in your makefile.
