Update Ocean2D example in FabUQCampaign.py to use the refactored EasyVVUQ

[djgroen]

It's this function:
def ocean2D(**args):
in this file:
http://www.github.com/wedeling/FabUQCampaign.py

SOFT DEADLINE: 23rd of May
HARD DEADLINE: 29th of May (but then you'll also have to revise the tutorial document in FabUQCampaign! ;))

I'll have a look at this early next week

Hi Derek, quick question. How do I run your ocean2D subroutine? My old script doesn't work any more now that run_UQ_sample is removed.

[djgroen]

Hi Wouter, That's strange, I thought that I'd kept your old script intact... Perhaps it's best to return run_UQ_sample to its original location then, so that we can keep using the old script as well? The new script is not fully functional yet, because I have to wait for EasyVVUQ to be updated. It can be run like your old script though (if run from config/Ocean2D), but I just noticed that I forgot to commit the new config files to the repository from my laptop :/. I'll try to get that sorted out tomorrow morning :). Cheers & apologies for the mistake there! -Derek

Okay, I committed the fix now. You can run the script through FabSim3 using

cd config_files/ocean2d
fab localhost ocean2d:ocean2d:label=1

I hope to be able to remove the first line after the refactoring with EasyVVUQ is done.

Hi Derek, I have Stochastic Collocation working with the refactored EasyVVUQ, although I haven't pushed the new version yet. Anyway, when I run your command above I get a Command(s) not found:ocean2d error, and the same when I try to run uq_ensemble from within my EasyVVUQ script. It seems I cannot access any subroutine in FabUQCampaign.py. Is there something which I might be messing up?

[wedeling]

I've pushed both the refactored advection diffusion and ocean model examples. I also updated both tutorials (the readme and the separate ocean tutorial). I'll fine tune them once we work out the issue above.

Hi @djgroen

I have managed to fix the issues above with the help of Hamid. Turns out that the import statements above the ocean_2d task in FabUQCampaign,py were creating a problem. If I comment them out, FabSim recognizes the other subroutines in the same file again.

I had another issues as well, which I fixed and pushed:

1. If I keep sim_ID fixed (i.e. the sim_ID needed for campaign2ensemble), and rerun a campaign with a different polynomial order, the old samples get executed again, along side the new ones. This is because the old samples do not get deleted from <fab_home>/config_files/<sim_ID>/SWEEP. I fixed this by assigning a dynamic sim_ID (the same name used for the EasyVVUQ campaign), such that it is different every time a campaign is launched.

2. The previous version had quite a lot of hard coded variables. I now made a more generic run_FabUQ_ensemble subroutine to run the ensemble. It is located in the same file as the example scripts. Only the fab home directory needs to be hard coded now.

I've updated the advection diffusion tutorial (https://github.com/wedeling/FabUQCampaign/blob/master/README.md) and the ocean tutorial (https://github.com/wedeling/FabUQCampaign/blob/master/Tutorial_ocean.md)

@wedeling I think we have this tutorial fully working, correct? If so, I think we can close this now :).

[wedeling]

I agree :)
