--- Comment #13 from Benjamin Schulz <schulz.benjamin at googlemail dot com> --- Hi many thanks for the effort. Sorry for the late reply. In desperation, by now I have tried to switch my code to openmp entirely and compile it with clang... But openacc has more parallelization levels (gang,loop, vector) as openmp since simd on gpu does not work with clang. Also, I found the teams distribute keyword of openmp very restrictive since once this appears, the code can not have commands between #pragma omp target and #pragma omp teams distribute. This makes it difficult to, do stuff on the target and then write a teams distribute loop on the device. So i will try openacc again... I use gentoo. They already have a gcc ebuild of the versions: https://packages.gentoo.org/packages/sys-devel/gcc 15.0.9999 : 15EAPI 8 ?amd64 ?x86 ?alpha ?arm ?arm64 ?hppa ?mips ?ppc ?ppc64 ?riscv ?sparc 15.0.1_pre20250323-r1 : 15EAPI Since the entire gentoo is compiled everyday with gcc, I suppose I will not switch to the 15.0.9999 version by now, which is the development code... I do not know if gcc version 15.0.1_pre20250323-r1 : 15EAPI contains the fixes already. If a sufficiently stable version of gcc appears that contains the fixes which compile my code, i will try them out happily and convert my code again to open acc when on the device, and use openmp when on the host, if this brings some speed.
