Fortran Compiler 2023.2.1

[AK33]

Hello,

I am trying to run the EIA's NEMS model (GitHub - EIAgov/NEMS). 

NEMS was compiled using a free download of the 23.2.0 release for Intel Fortran Compiler Classic and Intel Fortran Compiler for Windows (2023.2.1). The code does not run the the 2025 version of the compiler, nor with an earlier version (2024.2) that I was able to find on one of the threads on this forum.

To avoid having to change the underlying setup code for the model, I would prefer to just install the original version of the Fortran compiler and run the model in my VM setup. Is it possible to find the installation files for the 2023.2.1 version of the compiler anywhere? I was unable to find it on the Intel website.

Any help would be greatly appreciated!

You won't find this version unless you have active support.

Please have a look at this post:

I took a very quick look at the code. It is true that all configuration files (Makefiles, bash scripts, etc.) currently refer to version 2023.2.1 of the "ifort" compiler, with hard-coded paths. However, you should be able to adapt them without too much difficulty to use the newer "ifx" compiler. I would suggest searching the entire project for occurrences of “ifort” and replacing them with “ifx”, while updating the corresponding paths accordingly. A code that strictly depends on a specific compiler version would not be able to survive for very long anyway…
