Install Yambo on Ubuntu/LinuxMint with Intel compiler

The Intel compiler are freely available on Linux machines.
From the Intel oneAPI page, download and install:

• Intel Fortran Compiler
• Intel C++ Compiler
• Intel MPI libraries
• Intel MKL libraries.

notice that Intel compilers require g++ on your system to work properly if you did not installed it yet, just do it with the command:

sudo apt-get install g++

and then you need also the zlib in order to compile NetCDF and HDF5, that you can install with the command:

sudo apt install zlib1g zlib1g-dev

Now that you have installed all packages necessary to compile yambo, you can setup the Intel environment. If you use th bash/sh shell just do:

source /opt/intel/oneapi/setvars.sh

now all intel compilers and libraries will be in your path, you are ready to install Yambo. The Yambo configure automatically recognize BLAS, LAPACK and FFT from MKL, you have just to specify to use MKL also for BLACS and SCALAPACK.

./configure CC=icx MPICC=mpiicx MPIFC=mpiifort MPIF77=mpiifort FC=ifort F77=ifort --enable-open-mp --enable-par-linalg --with-scalapack-libs=mkl --with-blacs-libs=mkl --enable-slepc-linalg

finally compile the code with:

make core

Nota bene: every time you compile or use yambo, you have to load the Intel variables with the command: source /opt/intel/oneapi/setvars.sh
