[OOD-users] OOD-users Digest, Vol 17, Issue 7

Ben,

This seems to be possible with the current interactive app plugin capabilities.

Here is an example of the Jupyter app modified to display a text area to the user and modify the batch script, loading the desired modules prior to starting Jupyter:

and in particular

https://github.com/OSC/bc_example_jupyter/pull/6/commits/8227416bf95bae95381b3fdc4010e8f21e1292ad

At OSC we don’t do this so I’m not sure what limitations you would run into. One limitation that needs to be addressed is you can’t change the textarea size which makes editing multiple lines annoying with the default textarea size. That will be fixed in the next OnDemand version.

Thanks,
Eric

Morgan & Susan,

I brought this up at the PEARC BoF, but I would also like to echo here. I think it would be really nice to allow for a text input field that gets dumped to the job file that gets submitted. We could set a default so that they can see an example? I would expect the block of text to go right after any job submission parameters, before any commands get run. This would allow a user to set up their jupyter environment much more flexibly. They could even load the proper environments/modules for running other kernels available on the cluster, e.g. R, MATLAB.

Cheers,
Ben

Hi Susan,

Are you asking about how to give users a choice about how to select the Jupyter kernel of their choice? Or about the version of the Jupyter engine itself?

Subject: [OOD-users] Jupyter Notebooks in OnDemand

At the PEARC Open OnDemand BOF, I asked how OSC recommends we allow users change which version of Jupyter will be used for their session. OSC suggested creating a config file that will be read after the user brings up OnDemand.

I found docs about jupyter_notebook.config file but nothing regarding modules or versions.

Has anyone who is using OnDemand for Jupyter Notebooks figured out a way to do this .-- create a config file that allows users to customize which modules they load for use with Jupyter?  I haven't been able to find anything.

How is everyone else handling multiple versions within OnDemand?

Thanks in advance,

Susan Litzinger
