--- Comment #13 from Ron <caplanr at predsci dot com> ---
Hi,

I can confirm that gfortran 15 and gfortran 16 installed through apt with
ppa:ubuntu-toolchain-r/test recognize and compile the "do concurrent" reduce
clause.  

I cannot tell right now if the -ftree-parallelize-loops= is multi-threading the
reductions or falling back to serial, but either way the answers are correct.

The code I tested was HipFT (github.com/predsci/hipft) turning off the "GCC"
environment variable in the GCC configuration file.

Thanks!
