Installation | Vasp 5.4.4

Check the OUTCAR file for:

: Core source code, including a new parser directory (added in 5.4.4) for the LOCPROJ parser.

export PATH=/path/to/your/vasp.5.4.4.pl2/bin:$PATH

BLAS, LAPACK, ScaLAPACK, and FFTW (Intel MKL provides most of these). VASP - Vienna Ab initio Simulation Package Installation Steps 1. Extract and Patch the Source vasp 5.4.4 installation

Intel Fortran and C/C++ compilers are highly recommended (e.g., Intel oneAPI Base and HPC Toolkit MPI Library: Required for parallel execution (e.g., Intel MPI, OpenMPI). Numerical Libraries: Intel Math Kernel Library (MKL) provides optimized versions of BLAS, LAPACK, and ScaLAPACK. FFT Library: Typically included in MKL, but FFTW can also be used. VASP - Vienna Ab initio Simulation Package 2. Installation Steps outlines the standard build process for 5.4.x versions: Extract Source Code: Download your licensed source package (e.g., vasp.5.4.4.tar.gz ) and extract it: tar -xvzf vasp.5.4.4.tar.gz cd vasp.5.4.4 Configure Makefile: Copy a template from the

If you are operating on an open-source stack, copy the gfortran template: cp arch/makefile.include.linux_gfortran ./makefile.include Use code with caution.

You should see three files: vasp_std , vasp_gam , and vasp_ncl . If you see them, your installation was successful! Step 6: Set Your Environment Variables Check the OUTCAR file for: : Core source

Before beginning the installation, ensure your system has the following mandatory software:

Open the makefile.include file in a text editor to verify or adjust paths according to your specific cluster setup.

Copy the one closest to your system and rename it: Extract and Patch the Source Intel Fortran and

Intel Math Kernel Library (MKL) providing BLAS, LAPACK, ScaLAPACK, and BLACS.

: The gamma-only version for faster speed on big systems.

Add -DMPI_BLOCK=131072 for better GPU-MPI performance. Use NCCL (NVIDIA Collective Communications Library) by adding -DUSENCCL .

Intel Fortran ( ifort ) and C/C++ ( icc / icpc ) OR GNU GCC ( gfortran , gcc , g++ ). MPI Implementation: Intel MPI ( impi ) OR OpenMPI / MVAPICH.
