Bring back computing info on Piz Daint

[youwuyou]

In the "Software Update" section of the website this particular hyperlink to remote settings is now not pointing to any existing subsections .

It was on the discussion to bring back the setup for Piz Daint to the website, and I see it is essentially the content in this commit here.

Maybe we shall resolve it before the lecture 7 on 29th October?
