If you compiling Gromacs-2020.6 with Plumed2-2.7.2, do follow the Regression Test Errors during Gromacs Compilation. The Key issues are

DREGRESSIONTEST_DOWNLOAD=OFF -DREGRESSIONTEST_PATH=../regressiontests-2020.2

If you can download the regressiontests-2020.6.tar.gz and get the regressiontest PATH correct, it should work without issues.

To workaround,

Step 1: Download the Relevant Test from https://ftp.gromacs.org/regressiontests/

Step 2: Untar the regression test to the Gromacs Source Directory

% tar -zxvf  egressiontests-2019.6.tar.gz

Step 3: Create a script file

% touch gromacs_gpgpu.sh

Compiling Gromacs 5.0.4 on CentOS 6

Compiling Gromacs has never been easier using the cmake. There are a few assumptions.

  1. Use MKL and Intel Compilers
  2. Use OpenMPI  as the MPI-of-choice. The necessary PATH and LD_LIBRARY_PATH have been placed in .bashrc
  3. We will use SINGLE precision for speed used MDRUN and MPI Flags

Here is my configuration file using Intel Compilers

# tar xfz gromacs-5.0.4.tar.gz
# cd gromacs-5.0.4
# mkdir build
# cd build
# /usr/local/cmake-3.1.3/bin/cmake 
-DGMX_BUILD_OWN_FFTW=ON \
-DREGRESSIONTEST_DOWNLOAD=OFF \ 
-DCMAKE_INSTALL_PREFIX=/usr/local/gromacs-5.0.4 \
-DGMX_MPI=on \
-DGMX_FFT_LIBRARY=mkl \
-DMKL_LIBRARIES="/usr/local/intel/mkl/lib/intel64" \
-DMKL_INCLUDE_DIR="/usr/local/intel/mkl/include" \
-DGMX_DOUBLE=on \
-DGMX_BUILD_MDRUN_ONLY=off \ 
-DCMAKE_C_COMPILER=mpicc \ 
-DCMAKE_CXX_COMPILER=mpicxx
# make
# make check
# sudo make install
# source /usr/local/gromacs/bin/GMXRC

Installation Flags

–   -DCMAKE_C_COMPILER=xxx equal to the name of the C99 compiler you
    wish to use (or the environment variable CC)
–   -DCMAKE_CXX_COMPILER=xxx equal to the name of the C++98 compiler you
    wish to use (or the environment variable CXX)
–   -DGMX_MPI=on to build using an MPI wrapper compiler
–   -DGMX_GPU=on to build using nvcc to run with an NVIDIA GPU
–   -DGMX_SIMD=xxx to specify the level of SIMD support of the node on
    which mdrun will run
–   -DGMX_BUILD_MDRUN_ONLY=on to build only the mdrun binary, e.g. for
    compute cluster back-end nodes
–   -DGMX_DOUBLE=on to run GROMACS in double precision (slower, and not
    normally useful)
–   -DCMAKE_PREFIX_PATH=xxx to add a non-standard location for CMake to
    search for libraries
–   -DCMAKE_INSTALL_PREFIX=xxx to install GROMACS to a non-standard
    location (default /usr/local/gromacs)
–   -DBUILD_SHARED_LIBS=off to turn off the building of shared libraries
–   -DGMX_FFT_LIBRARY=xxx to select whether to use fftw, mkl or fftpack
    libraries for FFT support
–   -DCMAKE_BUILD_TYPE=Debug to build GROMACS in debug mode

Compiling and Installing Gromacs 4.6.2 with OpenMPI and Intel on CentOS 6

Step 1: Compiling cmake
To compile Gromacs 4.6.2, first you need to compile cmake 2.8 and above. At this point in writing, the current version is cmake 2.8.11.2

# tar -zxvf cmake-2.8.11.2.tar.gz
# cd cmake-2.8.11.2
# ./configure --prefix=/usr/local/cmake-2.8.11.2
# make
# make install

Step 2: Installing OpenMPI
See Blog Entry Building OpenMPI with Intel Compilers

Step 3: Installing FFTW (Single and Double Precision)
See Blog Entry Compiling and installing FFTW 3.3.3.

Step 4: Compiling Gromacs 4.6.2 (Single-Precision with Intel and OpenMPI)

# tar -zxvf gromacs-4.6.2.tar.gz
# cd gromacs-4.6.2
# mkdir build-cmake
# cd build-cmake
# CC=icc CMAKE_PREFIX_PATH=/usr/local/fftw-3.3.3-single/ /usr/local/cmake-2.8.11.2/bin/cmake .. 
-DCMAKE_INSTALL_PREFIX=/usr/local/gromacs-4.6.2-single-intel -DGMX_X11=OFF -DGMX_MPI=ON 
-DGMX_PREFER_STATIC_LIBS=ON -DBUILD_SHARED_LIBS=OFF
# make
# make install

Step 5: Compiling Gromacs 4.6.2 (Double Precision with Intel and OpenMPI)

# tar -zxvf gromacs-4.6.2.tar.gz
# cd gromacs-4.6.2
# mkdir build-cmake
# cd build-cmake
# CC=icc CMAKE_PREFIX_PATH=/usr/local/fftw-3.3.3-single/ /usr/local/cmake-2.8.11.2/bin/cmake .. 
-DCMAKE_INSTALL_PREFIX=/usr/local/gromacs-4.6.2-single-intel -DGMX_X11=OFF -DGMX_MPI=ON 
-DGMX_PREFER_STATIC_LIBS=ON -DBUILD_SHARED_LIBS=OFF -DGMX_DOUBLE=ON
# make 
# make install
