Intel have made their compiler much easier to use, its now not necessary to register a license, instead it’s now covered by an End User License Agreement.
Packed in their OneAPI tool, you will need a fair amount of disk space to download all the gubbins it comes with. The mkl library is part of the base package of oneAPI and ifort and another fortan compiler are available in the high performance computing package. The fortran compiler ifort supports Fortran 2018, a newer compiler ifx apparently that has an ‘LLVM backend’.
