@PierU, @ivanpribec and others are giving you good advice!

In our code, we always use `!$OMP PARALLEL DEFAULT(SHARED)` and then go through the parallel section with a fine-tooth comb and declare all variables which should be exclusive to each thread with `!$OMP PRIVATE`. This is required because the compiler would have a hard time figuring out our intent for each variable.

Interestingly, your variables `i` and `j` are private by default because they are loop variables. See [here](https://fortran-lang.discourse.group/t/parallelization-on-gpu-with-intel-compiler/7804/35).
