Vasp 5.4.4 Installation -

Complete Guide to VASP 5.4.4 Installation: Step-by-Step Compilation

Patches and version notes

: If the compilation fails during the linking stage with undefined references to MPI routines, ensure that the FC variable in makefile.include matches your installed MPI framework wrapper (e.g., mpiifort for Intel or mpif90 for OpenMPI).

Run a quick test to ensure the binaries link correctly to the dynamic libraries without immediate errors: vasp_std Use code with caution.

Before beginning, ensure you have the following:

Launch a quick calculation using your MPI runner to verify stable execution: mpirun -np 4 vasp_std Use code with caution.

Common build and runtime pitfalls (and fixes)

| Error | Possible Cause & Solution | | :--- | :--- | | | Cause : The Intel Fortran compiler environment is not loaded. Solution : Source the Intel environment script ( psxevars.sh ) or load the appropriate environment module. | | cannot open module file | Cause : This often indicates a compiler compatibility issue, especially when mixing GNU and Intel compilers, or using a newer GCC version (10+). Solution : Ensure -fallow-argument-mismatch is in your FFLAGS . | | Undefined reference to errfc_ | Cause : This is typically a problem with linking the MKL library, often when a patch or additional code (like VASPsol) is added. Solution : Double-check your LLIBS and BLACS definitions in makefile.include to ensure they match your MPI and threading library (e.g., -lmkl_blacs_intelmpi_lp64 for Intel MPI). | | Compilation hangs or fails on parser step | Cause : A known issue where the parser input files might be missing or the build process needs a clean start. Solution : Run make veryclean to remove all intermediate files and restart the make all command from scratch. | | Performance issues or MPI errors | Cause : Incorrect stack limit settings for large calculations. Solution : Before running VASP, use the command ulimit -s unlimited to remove restrictions on stack memory, which is crucial for many calculations. |

: GCC (Gfortran), OpenMPI, and an optimized BLAS/LAPACK library (like OpenBLAS or AMD AOCL). Step 1: Extracting the Source Code directory to the root directory to serve as

You will need to edit this file to point to your OpenMPI or MPICH installation and ensure FFTW is explicitly linked (as MKL is not present or requires specific GCC wrappers).

MPI module path not set. Solution:

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.
