Hello,
I have successfully installed gcc 8.1 with target offload on various systems.
Is there a flag to tell gcc to compile for a specific GPU type? I tried march=sm35, but this was not supported. I see k80, but I am not sure if that indeed target Nvidia Tesla K80 GPUs.
Thanks in advance for your advice,
Gabriele
