Hi Mahdi,

You can build your own offload toolchain using the instructions here:

https://gcc.gnu.org/wiki/Offloading#How_to_try_offloading_enabled_GCC

Alternatively, Ubuntu 18.04+ has a package "gcc-offload-nvptx".

Depending on your need, you may find that building your own from the 
devel/omp/gcc-9 (or gcc-10) git branch works better.

Hope that helps

Andrew
