: 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).
This extraction creates the root directory containing necessary source code files, structures, and pre-configured template files. Configuring the Makefile
A Comprehensive Guide to Installing VASP 5.4.4 The Vienna Ab initio Simulation Package (VASP) is a premier software package for performing ab initio quantum mechanical molecular dynamics simulations. Installing VASP 5.4.4 correctly requires a precise combination of compilers, numerical libraries, and Message Passing Interface (MPI) wrappers.
The compilation process can take anywhere from 10 to 30 minutes depending on your CPU. To speed up the compilation on a multi-core machine, use parallel execution with the -j flag: make -j 4 all Use code with caution. Step 4: Verify the Installation vasp 5.4.4 installation
Once compiled, binaries are located in the bin/ directory. You can verify the installation by running a small test job using mpirun : mpirun -n 4 /path/to/vasp.5.4.4/bin/vasp_std Use code with caution. Copied to clipboard
| Common Error | Likely Cause | Potential Fix | | :--- | :--- | :--- | | | Compiler version incompatibility with the source code. | Try a different compiler version (e.g., older Intel) or apply the latest official VASP patch. | | Error: Assignment to contiguous pointer from non-contiguous target | Strict Fortran 2008 compliance of newer gfortran versions. | Compile with -std=legacy flag or use an older GCC version. | | **"cannot create directory build/std': File exists"** | An incomplete or failed previous build left artifacts. | Run make veryclean to clean the build directory completely before recompiling. | | **Linking errors or "undefined reference"** | Missing or incorrectly linked libraries, especially MKL or FFTW. | Double-check the LLIBS and INCS paths in your makefile.include . Ensure that the MKLROOT` environment variable is set correctly or specify the full path. |
First, navigate to your desired installation directory, copy the source archive there, and unpack it using the terminal. tar -xvf vasp.5.4.4.tar.gz cd vasp.5.4.4 Use code with caution. : If the compilation fails during the linking
Before launching high-throughput production runs, execute a short test calculation to ensure the binaries work correctly. 1. Create a Test Directory
Create a simple test directory with example inputs (e.g., a silicon bulk calculation). Run with 2-4 MPI processes:
Open the makefile.include file with a text editor (like nano or vi ). For a standard Intel Parallel Studio / OneAPI setup, you usually need to verify these paths: Installing VASP 5
A typical Slurm job submission script for a parallel VASP calculation on a cluster might look like this:
Mixed compiler versions or leftover objects. Solution: make veryclean and re-extract from tarball.
This is where you link to Intel MKL. The exact paths may vary, but a common pattern is:
Inside this directory, you will find the core source files and a sub-folder named arch containing various template configuration files ( makefile.include.* ). Step 2: Configure the Build Environment
