Subject: How to Compile vasp.5.4.4.tar.gz on Modern Clusters

So you’ve received the vasp.5.4.4.tar.gz archive from your PI or the VASP portal. Before you start compiling, here is a quick checklist to ensure your build runs efficiently on modern hardware.

Step 1: The Makefile Version 5.4.4 changed the compilation game by introducing the makefile.include system. You no longer need to edit the main Makefile directly. Copy makefile.include.linux_intel (or the appropriate template for your architecture) to the root directory and name it makefile.include.

Step 2: Compiler Flags If you are building on a cluster with Intel CPUs, stick with the Intel compilers (mpiifort).

Step 3: Libxc Integration VASP 5.4.4 was one of the first versions to play nicely with external libraries for meta-GGAs. If you plan on using SCAN or other advanced functionals, ensure you link the libxc library in your makefile.

Common Error: If you get a segmentation fault immediately upon running, it is usually an OpenMP conflict. Try setting: export OMP_NUM_THREADS=1 in your submission script, or recompile with -qopenmp flags removed if you don't need threading.

Happy computing!

Part 3: The Contents of the Tarball – What’s Inside?

Once you have obtained a legitimate copy of vasp.5.4.4.tar.gz and extracted it (tar -xzf vasp.5.4.4.tar.gz), you will find a specific directory structure. Understanding this is key to successful compilation.

| Directory / File | Purpose | | :--- | :--- | | src/ | The Fortran source code (.F and .f files). This is the heart of VASP. | | makefile.include | The master configuration file. You must edit this for your specific HPC environment. | | build/ | A newer structure (introduced around 5.4.4) for out-of-source builds to keep source tree clean. | | arch/ | Example makefile templates for various compilers (Intel, GNU, NEC, Cray). | | lib/ | Pre-compiled libraries (e.g., for FFTW, LAPACK). | | testsuite/ | A suite of input files (INCAR, POSCAR, POTCAR, KPOINTS) to verify your build is correct. |

Key takeaway: Version 5.4.4 moved toward a modular build system, which allows you to compile multiple variants (e.g., standard, gamma-only, non-collinear) from the same source without cross-contamination.

Fortran Compiler: Intel ifort is the industry standard for VASP, though gfortran can be used. MPI Library: Such as Intel MPI, OpenMPI, or MPICH.

Mathematical Libraries: Optimized BLAS, LAPACK, and ScaLAPACK (often bundled in Intel MKL). FFTW: A library for computing discrete Fourier transforms. 📦 Step 1: Extraction and Patching

Once you have your vasp.5.4.4.tar.gz file, the first step is to unpack it: tar -zxvf vasp.5.4.4.tar.gz cd vasp.5.4.4 Use code with caution. Copied to clipboard

VASP often requires specific patches to fix minor bugs or improve compatibility with certain hardware. For instance, if you have a patch file like patch.5.4.4.16052018.gz, you should apply it before compiling:

gunzip patch.5.4.4.16052018.gz patch -p0 < patch.5.4.4.16052018 Use code with caution. Copied to clipboard ⚙️ Step 2: Configuring the Build

Unlike many modern software packages that use cmake, VASP 5.4.4 uses a template-based makefile.include system. You will find several templates in the arch/ directory.

Choose a template: Copy the one that most closely matches your architecture. cp arch/makefile.include.linux_intel makefile.include Use code with caution. Copied to clipboard

Edit makefile.include: Open the file in a text editor to ensure the paths to your compilers and libraries (like MKL) are correct.

GPU Support (Optional): If you are compiling for NVIDIA GPUs, you must ensure the CUDA_ROOT is correctly defined in your makefile.include. 🚀 Step 3: Compilation

VASP 5.4.4 allows you to build three main versions of the executable: std: The standard version for most calculations.

gam: A version optimized for calculations involving only the Gamma point.

ncl: The non-collinear version for magnetic or spin-orbit coupling studies. Run the following command to build all three: make all Use code with caution. Copied to clipboard

The resulting binaries will be located in the bin/ directory. ✅ Step 4: Verification

After a successful build, it is critical to run a test job. You can use standard benchmark sets or a simple bulk silicon calculation to verify that the MPI parallelization and numerical results are consistent with known values. Pro-Tips for Success vasp.5.4.4.tar.gz

Clean before recompiling: If you change your makefile.include, always run make clean before restarting the build.

Stack limits: In your submission scripts, remember to set ulimit -s unlimited to avoid memory-related crashes.

Documentation: Always refer to the official VASP Wiki for the most detailed information on input parameters.
