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:

apt-get install g++

then in the bash/sh shell you can setup the Intel environment variables by doing:

source /opt/intel/oneapi/setvars.sh

now 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 FC=mpiifort F77=mpiifort  --enable-open-mp --enable-par-linalg --enable-hdf5-par-io \
--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
