FYI [Version 5.2 of the AMD AOCC compiler](https://www.amd.com/en/developer/aocc.html) has been released. A DO CONCURRENT parallelization feature was added in Fortran. Also, the next major release, Version 6, will be based on llvm-flang and not “classic” flang like current versions. ---

@Ali do you know if you can include the aocc compiler into [setup-fortran](https://github.com/fortran-lang/setup-fortran) with conda? it would be pretty cool ! ---

@jorgeg yes, good idea! AOCC is included now in [setup-fortran-conda](https://github.com/gha3mi/setup-fortran-conda).

What will be its relation with [AOMP](https://github.com/ROCm/aomp/tree/aomp-dev), “an open source Clang/LLVM based compiler” by AMD (it provides `flang` under the name `amdflang`)? ---

My understanding is the AOMP compilers are a development branch targeting OpenMP on Radeon GPU’s based on LLVM. It is part of the [AMD Open Source Stack (AKA ROCm)](https://www.amd.com/en/products/software/rocm.html) for GPU computation. AOCC targets AMD Zen processors but will (hopefully) support GPU offloading at some time. ---

I’m a bit confused now ;). I used `amdflang` as a wrapper for AOCC because I saw that `amdflang` is supported in `fpm` : [fpm/src/fpm\_compiler.F90 at main · fortran-lang/fpm · GitHub](https://github.com/fortran-lang/fpm/blob/main/src/fpm_compiler.F90) However, I’m no longer sure whether this refers to AOCC or AOMP, so I’d like to make sure I’m using the correct compiler identifier. Any suggestions? ---

AOCC is the standard “classic flang” plus clang/clang++ and is “tuned” for AMD Zen family processors but should work for other AMD64 processors (Intel). Its based on a LLVM 17 release (kinda old). AOMP is a development branch based on the most recent LLVM (I think 22 with 23 in the works). As best as I can tell it is where AMD does their development on OpenMP for Radeon GPUs. I presume that it will support offloading to Radeon GPUs via OpenMP but don’t quote me on it. I think AMDs AOMP work will filter back into mainline LLVM flang at some point. For now, unless you really want to play around with OpenMP on a Radeon GPU, AOCC is the release you want to install if you have a Zen processor.
