--- Comment #4 from Ioannis E. Venetis <venetis at ceid dot upatras.gr> --- It seems that the problem was indeed some kind of confusion due to multiple gcc installs. I removed the nvptx related packages of gcc-9.3.0 from my Ubuntu 16.04.7 LTS system (packages gcc-9-offload-nvptx, libgomp-plugin-nvptx1 and nvptx-tools). After recompiling the test application I get the correct results with OpenACC (and with OpenMP). Why this problem happens and why it only affects OpenACC might still be interesting to investigate.
