Solves #3910.

However, if it was just a typo and GPU support is in fact enabled, we can use this PR to pass the correct architecture to the grid and enable GPU tests

Let me know @jlk9 @wsmoses @glwagner

What's the problem? Why disable the tests?

It's running on the CPU so it is a duplicate of the Tartarus one, but it takes quite some time on Sverdrup because the CPU there is not that great.

If they take too long to run / compile, we will have to come up with a differerent strategy

How long do they take right now?

It was taking upwards of an hour. But on the GPU I imagine it takes less.

The distributed tests take 2h right?

About an hour, but it depends if there is space on the cluster or not.
