Next steps: I am not planning to take on this project. This is just an initial report found. Please feel free to work on this.

SNbone:

https://proxyapps.exascaleproject.org/app/snbone/
https://github.com/ANL-CESAR/SNbone

Initial report for SNbone:

• Minimum version of Fortran required using gfortran: F95
  • Required arguments to compile with version: "-fdec"
• How to compile with gfortran:
  1. First you can download the project by running in bash:

  git clone https://github.com/ANL-CESAR/SNbone.git
  cd SNbone
  

  2. Now you can compile the project by running:

  cd src_fortran
  make COMPILER=gfortran
  

  By default, SNbone compiles with OpenMP. To turn this off you can append THREAD=no when calling make.
• Does it compile with flang-new: No
  When running make FF=flang-new LD=flang-new we get a missing abort intrinsic lowering error:

  flang-new -c      -o Basic_Abort.o Basic_Abort.F90
  error: loc("./Basic_Abort.F90":21:1): TODO: missing intrinsic lowering: abort
  make: *** [Makefile:128: Basic_Abort.o] Error 1
  

Versions:

• gfortran version used: 9.3.0
• flang-new, fir-dev branch, HEAD: fb8eb63
• Architecture for compilation: aarch64
