+# Installation script for GPAW 20.1.0:
+# * We compile our own Python as this is the best guarantee to not have to
+#   struggle with compatibility problems between various compilers used for
+#   various components
+# * Using the matching version of ase, 3.19.3
+# * Compiling with the Intel compilers
+#
+# The FFT library is discovered at runtime. With the settings used in this script
+# this should be MKL FFT, but it is possible to change this at runtime to either
+# MKL, FFTW or the built-in NumPy FFT routines, see the installation instructions
+# (link below).

+Description
+===========
+
+GPAW $GPAW_version for the UEABS benchmark.
+
+Configuration:
+  * Parallel GPAW $GPAW_version with ase $ase_version
+  * Using FFTW for the FFT computations and MKL for the BLAS/Lapack
+  * Minimal use of system libraries or libraries that are installed
+    through package managers such as EasyBuild or Spack.
+
+Detailed configuration:
+  * Compiler module: $compiler_module, used for all packages
+  * Python dependencies:
+      * zlib $zlib_version
+      * ncurses $ncurses_version
+      * readline $readline_version
+      * SQLite $sqlite_version
+      * libffi $libffi_version
+  * FFTW $fftw_version
+  * libxc $libxc_version
+  * Python $python_version
+  * Important Python packages: numpy-$numpy_version, scipy-$scipy_version, ase-$ase_version, gpaw-$GPAW_version
+  * Additional Python packages: wheel-$wheel_version, cython-$cython_version
+  * GPAW setups $GPAWsetups_version

+===========
+
+GPAW $GPAW_version for the UEABS benchmark.
+
+Configuration:
+  * Parallel GPAW $GPAW_version with ase $ase_version
+  * Using FFTW for the FFT computations and MKL for the BLAS/Lapack
+  * Minimal use of system libraries or libraries that are installed
+    through package managers such as EasyBuild or Spack.
+
+Detailed configuration:
+  * Compiler module: $compiler_module, used for all packages
+  * Python dependencies:
+      * zlib $zlib_version
+      * ncurses $ncurses_version
+      * readline $readline_version
+      * SQLite $sqlite_version
+      * libffi $libffi_version
+  * FFTW $fftw_version
+  * libxc $libxc_version
+  * Python $python_version
+  * Important Python packages: numpy-$numpy_version, scipy-$scipy_version, ase-$ase_version, gpaw-$GPAW_version
+  * Additional Python packages: wheel-$wheel_version, cython-$cython_version
+  * GPAW setups $GPAWsetups_version

+
+GPAW $GPAW_version for the UEABS benchmark.
+
+Configuration:
+  * Parallel GPAW $GPAW_version with ase $ase_version
+  * Using FFTW for the FFT computations and MKL for the BLAS/Lapack
+  * Minimal use of system libraries or libraries that are installed
+    through package managers such as EasyBuild or Spack.

+# Installation script for GPAW 20.1.0:
+# * We compile our own Python as this is the best guarantee to not have to
+#   struggle with compatibility problems between various compilers used for
+#   various components
+# * Using the matching version of ase, 3.19.3
+# * Compiling with the Intel compilers
+#
+# The FFT library is discovered at runtime. With the settings used in this script
+# this should be MKL FFT, but it is possible to change this at runtime to either
+# MKL, FFTW or the built-in NumPy FFT routines, see the installation instructions
+# (link below).

+Description
+===========
+
+GPAW $GPAW_version for the UEABS benchmark.
+
+Configuration:
+  * Parallel GPAW $GPAW_version with ase $ase_version
+  * Using FFTW for the FFT computations and MKL for the BLAS/Lapack
+  * Minimal use of system libraries or libraries that are installed
+    through package managers such as EasyBuild or Spack.
+
+Detailed configuration:
+  * Compiler module: $compiler_module, used for all packages
+  * Python dependencies:
+      * zlib $zlib_version
+      * ncurses $ncurses_version
+      * readline $readline_version
+      * SQLite $sqlite_version
+      * libffi $libffi_version
+  * FFTW $fftw_version
+  * libxc $libxc_version
+  * Python $python_version
+  * Important Python packages: numpy-$numpy_version, scipy-$scipy_version, ase-$ase_version, gpaw-$GPAW_version
+  * Additional Python packages: wheel-$wheel_version, cython-$cython_version
+  * GPAW setups $GPAWsetups_version

+Description
+===========
+
+GPAW $GPAW_version for the UEABS benchmark.
+
+Configuration:
+  * Parallel GPAW $GPAW_version with ase $ase_version
+  * Using FFTW for the FFT computations and MKL for the BLAS/Lapack
+  * Minimal use of system libraries or libraries that are installed
+    through package managers such as EasyBuild or Spack.
+
+Detailed configuration:
+  * Compiler module: $compiler_module, used for all packages
+  * Python dependencies:
+      * zlib $zlib_version
+      * ncurses $ncurses_version
+      * readline $readline_version
+      * SQLite $sqlite_version
+      * libffi $libffi_version
+  * FFTW $fftw_version
+  * libxc $libxc_version
+  * Python $python_version
+  * Important Python packages: numpy-$numpy_version, scipy-$scipy_version, ase-$ase_version, gpaw-$GPAW_version
+  * Additional Python packages: wheel-$wheel_version, cython-$cython_version
+  * GPAW setups $GPAWsetups_version

+Description
+===========
+
+GPAW $GPAW_version for the UEABS benchmark.
+
+Configuration:
+  * Parallel GPAW $GPAW_version with ase $ase_version
+  * Using FFTW for the FFT computations and MKL for the BLAS/Lapack
+  * Minimal use of system libraries or libraries that are installed
+    through package managers such as EasyBuild or Spack.
+
+Detailed configuration:
+  * Compiler module: $compiler_module, used for all packages
+  * Python dependencies:
+      * zlib $zlib_version
+      * ncurses $ncurses_version
+      * readline $readline_version
+      * SQLite $sqlite_version
+      * libffi $libffi_version
+  * FFTW $fftw_version
+  * libxc $libxc_version
+  * Python $python_version
+  * Important Python packages: numpy-$numpy_version, scipy-$scipy_version, ase-$ase_version, gpaw-$GPAW_version
+  * Additional Python packages: wheel-$wheel_version, cython-$cython_version
+  * GPAW setups $GPAWsetups_version

+# * Compiling with the Intel compilers

+GPAW $GPAW_version for the UEABS benchmark.
+
+Configuration:
+  * Parallel GPAW $GPAW_version with ase $ase_version
+  * Using FFTW for the FFT computations and MKL for the BLAS/Lapack
+  * Minimal use of system libraries or libraries that are installed
+    through package managers such as EasyBuild or Spack.
+
+Detailed configuration:
+  * Compiler module: $compiler_module, used for all packages
+  * Python dependencies:
+      * zlib $zlib_version
+      * ncurses $ncurses_version
+      * readline $readline_version
+      * SQLite $sqlite_version
+      * libffi $libffi_version
+  * FFTW $fftw_version
+  * libxc $libxc_version
+  * Python $python_version
+  * Important Python packages: numpy-$numpy_version, scipy-$scipy_version, ase-$ase_version, gpaw-$GPAW_version

+# Build issues at LRZ
+
+## Compilers used for testing
+
+The following compilers, available on the system at the time of testing and installed
+with Spack, were used:
+
+  * Intel C/C++/Fortran version 19.1.2.254 (as provided by the intel/2020.0.2 module)
+  * Intel MPI version 2019.8.254
+  * Intel MKL 2020.1.217
+
+These are components from the Intel compilers version 2020 update 2.
+
+## Issues
+
+  * It is impossible to download files from this system, so all sources have to be
+    put in place manually before starting the compile. The scripts will generate the
+    necessary URLs.
+
+  * A general issues: At some patch releases of Python 3.8 and 3.9 changes were made
+    to certain components of the code that installs additional packages. This causes
+    failures in the installation process of NumPy and SciPy. So it is better to stick
+    to the versions used in these example scripts (Python 3.8.7 and 3.9.4).
+
+  * GPAW tried to compile a file that includes an MPI header with the regular C compiler.
+    The solution was to set the regular C compiler to the MPI wrapper compiler script.
+
+    That issue does not occur on all systems since some systems have the MPI header
+    files included in ``CFILES`` so that the regular C compile also finds those header
+    files.
+
+  * We failed to get the combination Python 3.9.4 + NumPy 1.19.5 + SciPy 1.5.4 to compile.
+    It failed during the installation of SciPy, even though this combination worked on
+    several other systems.
+
+  * The system uses TCL modules 4.6 at the time of testing. We failed to get the right
+    compiler (which were not the default on the system) to load in the module file
+    unless we first manually unloaded intel-mkl, intel-mpi and intel.
+
+    There are no examples on how to do this in the existing module files of the system
+    which may be due to the fact that spack with rpath is being used.
+
+    It might have been a better solution to simply unload spack and use the other
+    compiler modules that are not spack-managed instead rather than a variant of the
+    default environment as presented by the system.

+Description
+===========
+
+GPAW $GPAW_version for the UEABS benchmark.
+
+Configuration:
+  * Parallel GPAW $GPAW_version with ase $ase_version
+  * Using FFTW for the FFT computations and MKL for the BLAS/Lapack
+  * Minimal use of system libraries or libraries that are installed
+    through package managers such as EasyBuild or Spack.
+
+Detailed configuration:
+  * Compiler module: $compiler_module, used for all packages
+  * Python dependencies:
+      * zlib $zlib_version
+      * ncurses $ncurses_version
+      * readline $readline_version
+      * SQLite $sqlite_version
+      * libffi $libffi_version
+  * FFTW $fftw_version
+  * libxc $libxc_version
+  * Python $python_version
+  * Important Python packages: numpy-$numpy_version, scipy-$scipy_version, ase-$ase_version, gpaw-$GPAW_version
+  * Additional Python packages: wheel-$wheel_version, cython-$cython_version
+  * GPAW setups $GPAWsetups_version
+
+Before loading the module you have to ensure that some modules in the default
+environment are unloaded which could not be done reliably from this module:
+
+module unload intel-mkl intel-mpi intel

+GPAW $GPAW_version for the UEABS benchmark.
+
+Configuration:
+  * Parallel GPAW $GPAW_version with ase $ase_version
+  * Using FFTW for the FFT computations and MKL for the BLAS/Lapack
+  * Minimal use of system libraries or libraries that are installed
+    through package managers such as EasyBuild or Spack.
+
+Detailed configuration:
+  * Compiler module: $compiler_module, used for all packages
+  * Python dependencies:
+      * zlib $zlib_version
+      * ncurses $ncurses_version
+      * readline $readline_version
+      * SQLite $sqlite_version
+      * libffi $libffi_version
+  * FFTW $fftw_version
+  * libxc $libxc_version
+  * Python $python_version
+  * Important Python packages: numpy-$numpy_version, scipy-$scipy_version, ase-$ase_version, gpaw-$GPAW_version
+  * Additional Python packages: wheel-$wheel_version, cython-$cython_version
+  * GPAW setups $GPAWsetups_version
+
+Before loading the module you have to ensure that some modules in the default
+environment are unloaded which could not be done reliably from this module:

+# Installation script for GPAW 20.1.0:
+# * We compile our own Python as this is the best guarantee to not have to
+#   struggle with compatibility problems between various compilers used for
+#   various components
+# * Using the matching version of ase, 3.19.3
+# * Compiling with the Intel compilers
+#
+# The FFT library is discovered at runtime. With the settings used in this script

+Description
+===========
+
+GPAW $GPAW_version for the UEABS benchmark.
+
+Configuration:
+  * Parallel GPAW $GPAW_version with ase $ase_version
+  * Using FFTW for the FFT computations and MKL for the BLAS/Lapack
+  * Minimal use of system libraries or libraries that are installed
+    through package managers such as EasyBuild or Spack.
+
+Detailed configuration:
+  * Compiler module: $compiler_module, used for all packages
+  * Python dependencies:
+      * zlib $zlib_version
+      * ncurses $ncurses_version
+      * readline $readline_version
+      * SQLite $sqlite_version
+      * libffi $libffi_version
+  * FFTW $fftw_version
+  * libxc $libxc_version
+  * Python $python_version
+  * Important Python packages: numpy-$numpy_version, scipy-$scipy_version, ase-$ase_version, gpaw-$GPAW_version
+  * Additional Python packages: wheel-$wheel_version, cython-$cython_version
+  * GPAW setups $GPAWsetups_version

+Description
+===========
+
+GPAW $GPAW_version for the UEABS benchmark.
+
+Configuration:
+  * Parallel GPAW $GPAW_version with ase $ase_version
+  * Using FFTW for the FFT computations and MKL for the BLAS/Lapack
+  * Minimal use of system libraries or libraries that are installed
+    through package managers such as EasyBuild or Spack.
+
+Detailed configuration:
+  * Compiler module: $compiler_module, used for all packages
+  * Python dependencies:
+      * zlib $zlib_version
+      * ncurses $ncurses_version
+      * readline $readline_version
+      * SQLite $sqlite_version
+      * libffi $libffi_version
+  * FFTW $fftw_version
+  * libxc $libxc_version
+  * Python $python_version
+  * Important Python packages: numpy-$numpy_version, scipy-$scipy_version, ase-$ase_version, gpaw-$GPAW_version
+  * Additional Python packages: wheel-$wheel_version, cython-$cython_version
+  * GPAW setups $GPAWsetups_version
