Build on Marconi

Here we provide the instructions for building MILADY on the widely used supercomputer MARCONI.

Note

We describe here the way that we use and we know that it works. If you know a better procedure, we are happy to learn about your experience. You can email us to update the present documentation.

Step 1: Loading modules and setting bash environment

In the following, MILADY refers to the GitHub repository. We preserve here the same structure of the directories as in previous examples.

Create a directory MLD and copy MILADY in that location. Hereafter, ${MLD} is the location of MLD directory.

Set your bash environment. My ${HOME}/.bashrc file contains the following modules and variables:

module load env-skl
module load intel/pe-xe-2020--binary
module load mkl/2020--binary
module load intelmpi/2020--binary
module load cmake/3.18.2
export I_MPI_FC=ifort
export I_MPI_F90=ifort
export I_PMI_CXX=g++
export I_MPI_CC=gcc

Note

mld_build and mld_install will be created by the installation procedure, whilst mld_testdir is a directory with tests that is not compulsory.

Define in your environment the following bash function (can be added at the end of your ${HOME}/.bashrc file)

function f_setenv_milady{
  unset MLD_ROODIR
  unset MLD_SCRDIR
  unset MLD_SRCDIR
  unset MLD_BUIDIR
  unset MLD_INSDIR
  unset MLD_TESDIR
  unset MLD_SETENV
  unset OMP_INSDIR
  unset OMP_ROOT

  export MLD_ROODIR="${MLD}/"

  export MLD_SRCDIR=${MLD_ROODIR}/MILADY
  export MLD_BUIDIR=${MLD_ROODIR}/mld_build
  export MLD_INSDIR=${MLD_ROODIR}/mld_install
  export MLD_TESDIR=${MLD_ROODIR}/mld_testdir
  export MLD_SETENV=ON
  export MKL_ROOT=${MKLROOT}
  export OMP_INSDIR=/cineca/prod/opt/compilers/intel/pe-xe-2020/binary/impi/2019.9.304/intel64/
  export OMP_ROOT=/cineca/prod/opt/compilers/intel/pe-xe-2020/binary/impi/2019.9.304/intel64/

  export PATH=${MLD_ROODIR}/MILADY/scripts:${PATH}
}

Step 2: Installation

Charge the MILADY bash environment (do not forget to source your $HOME/.bashrc file before it):
```
f_setenv_milady
source ${MLD}/MILADY/scripts/compile_milady.bash
```
Note

Do not forget that ${MLD} is defined by you. It is the path to the MLD directory.
Install MILADY:
```
f_compile_milady_intel
make -j6
```

And that is it ! The executable is in bin/milady_main.exe.
