--- 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! - Ron
