Vasp 5.4.4 Installation Review

Because VASP is not a "plug-and-play" application, you must compile it from source code specifically for your hardware. This guide covers the standard installation process using and MKL , which generally yields the best performance. 1. Prerequisites and Dependencies

Add to ~/.bashrc for convenience.

: Many users apply specific stability patches (e.g., patch.5.4.4.16052018 ) to fix known bugs in the initial 5.4.4 release. 2. Configuration ( makefile.include ) vasp 5.4.4 installation

VASP 5.4.4 uses a flexible build system that relies on a makefile.include file.

FC = mpiifort -qopenmp FCL = mpiifort -qopenmp Because VASP is not a "plug-and-play" application, you

If using ScaLAPACK/ELPA, ensure corresponding flags and libraries are set; then: make alldir

: If you need only one version, you can use the specific targets: Prerequisites and Dependencies Add to ~/

Ensure the version of MPI used to compile VASP is the same one used to run it ( mpirun vs mpiexec ).

Essential for parallel versioning (e.g., Intel MPI or OpenMPI ). Numerical Libraries: BLAS/LAPACK: For basic linear algebra operations. ScaLAPACK: For distributed-memory parallel processing.
