Vasp 5.4.4: Installation Updated

This paper outlines the technical workflow and optimization strategies for installing VASP 5.4.4 , a pivotal version that introduced the SCAN meta-GGA functional and enhanced GPU support . 🏗️ Technical Architecture of VASP 5.4.4 The installation process for version 5.4.4 differs from older versions (pre-5.4) due to a centralized build system that allows for simultaneous compilation of multiple binaries. Modular Build Tree : root/src : Core source files and low-level makefile. root/arch : Pre-configured makefile.include templates for various architectures. root/bin : Final resting place for compiled binaries. The Three Pillars : A standard installation typically yields three distinct executables: vasp_std : Standard version for general calculations. vasp_gam : Optimized specifically for Gamma-point only calculations. vasp_ncl : For non-collinear magnetic structures and spin-orbit coupling. 🛠️ Step-by-Step Installation Protocol According to official and institutional guides like those from VASP Wiki and Purdue RCAC , the workflow follows a specific sequence: 1. Source Preparation & Patching Unpacking : Extraction of the vasp.5.4.4.tar.gz archive. Mandatory Patching : 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 ) Users must select a template from the /arch directory that matches their hardware. Intel Environments : Typically uses makefile.include.linux_intel . GNU/OpenMPI : Requires makefile.include.linux_gnu . Key Dependencies : Installation requires a Fortran/C compiler, an MPI implementation, and numerical libraries like BLAS , LAPACK , and ScaLAPACK . 3. Compilation Mass Build : Running make all compiles all three core versions sequentially. Targeted Build : Individual versions can be compiled using make std , make gam , or make ncl . 🚀 Advanced Optimization & Extensions VASP 5.4.4 is often customized for specific research needs beyond the standard build: Installing VASP.5.X.X - VASP Wiki

VASP 5.4.4 — Installation report (comprehensive, practical) Summary

VASP 5.4.4 is a legacy (5.x) release of the Vienna Ab‑initio Simulation Package; it requires a paid license and is distributed to licensees from the VASP project. Building is done from source on Linux and typically requires Fortran/C compilers, MPI, BLAS/LAPACK/ScaLAPACK, FFTW (or MKL FFT), and optional CUDA/MAGMA for GPU support. Below is a structured, actionable guide covering prerequisites, preparatory steps, makefile tuning, common build recipes (Intel/MKL, GNU+FFTW, GPU), testing, common pitfalls and suggested verification.

Prerequisites and licensing

Obtain the VASP 5.4.4 source tarball from the VASP maintainers (license required). Supported tooling (typical): Fortran compiler (ifort/mpiifort, pgfortran, gfortran), C/C++ compilers (icc/icc/ icpc or gcc/g++), MPI implementation (Intel MPI, OpenMPI, MVAPICH2), numerical libraries: BLAS/LAPACK (or MKL), ScaLAPACK & BLACS (for parallel large-scale jobs), FFT library (FFTW3 or MKL FFTW interface), optional: CUDA toolkit + MAGMA for GPU port. OS: x86_64 Linux (RHEL/CentOS/Ubuntu variants commonly used). Kernel/libc compatibility matters if using prebuilt MKL/Intel toolkits.

Directory structure (VASP 5.x)

Root directory layout:

arch/: sample makefile.include.arch files src/: source files and .objects lists build/: build subdirectories for vasp_std, vasp_gam, vasp_ncl, etc. bin/: destination for executables

Copy a suitable arch/makefile.include.* to root/makefile.include and edit to match your environment.

High‑level steps

Unpack source:

tar -xzf vasp.5.4.4.tar.gz cd vasp.5.4.4
