[firedrake] Progress on installing PyOP2/firedrake on ARCHER

[Eike Mueller]

Hi Florian,

thanks a lot for your reply and for updating the wiki, I got a bit further now.

ok, I will use the environment script as it is and not worry about the fact that the anaconda library breaks the module command at the moment. Let's see if the support can figure something out.

It works with the updated instructions on the webpage. Strangely, if I clone a repository into a directory, delete this directory and then try to clone again with exactly the same command, nothing happens.

I will ignore this then, and just call the setup.py script twice in the PyOP2 directory.

I tried a simpler hello-world script where I swap python -> anaconda and run a python script. This does work.
Still trying to run the poisson example from the benchmark repository, but the ARCHER queues seem to be terribly slow, even if I just run on one node on the debug queue :-(

I think I already have access to the repository, so will edit if necessary.

Thanks a lot,

Eike
