| Problem | Solution | |---------|----------| | cannot open file libifcore.a | Switch from ifort to mpiifort in FC and FCL | | Precompiler errors with -Duse_collective | Comment out that line – not needed in 5.4.4 for most HPC setups | | scalapack not found | Explicitly add -lmkl_scalapack_lp64 -lmkl_blacs_intelmpi_lp64 | | GPU build fails | Use -DOPENACC only if using NVHPC; else build CPU-only first | vasp 5.4.4 installation

(Refer to the VASP Wiki for the latest patching procedures). 3. Configure makefile.include

Check with grep "energy without entropy" OUTCAR – you should see reasonable numbers.

gam : A version optimized specifically for calculations restricted to the Gamma-point, which runs significantly faster and uses less memory for large isolated systems (like molecules).

The general steps for a standard Linux installation are as follows: mkdir ~/vasp_test cd ~/vasp_test cp

: Ensure FC points to your MPI Fortran compiler (like mpiifort or mpif90 ).

Successfully installed VASP 5.4.4 – compilation notes and common pitfalls

make gam # For gamma-only calculations (faster for molecules/clusters) make ncl # For non-collinear magnetism / spin-orbit coupling

Installing (The Vienna Ab initio Simulation Package) is a milestone for many computational researchers. While newer versions exist, 5.4.4 remains a "workhorse" version due to its stability and compatibility with various legacy scripts. Choose the one that matches your system and

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

Technical Overview: VASP 5.4.4 Installation and Compilation The Vienna Ab initio Simulation Package (VASP) 5.4.4 is a widely used release that introduced features such as the and improved GPU port performance. Successfully installing VASP 5.4.4 requires a specific build environment, careful management of numerical libraries, and modifications to the core configuration files. 1. Mandatory Prerequisites

vasp_gam : Gamma-point-only version for increased speed on large systems. vasp_ncl : Non-collinear version for spin-orbit coupling. : make all Use code with caution. Copied to clipboard

I just completed a fresh installation of on a Linux cluster (CentOS 7.9, Intel Xeon Gold, NVIDIA V100 GPUs). I wanted to share the working configuration and highlight a few issues I encountered.
