Hi @hdrake

  • what do you have in mind for this 2h session? 3 x 20' overview presentations from @fionaclerc , @thabbott , and myself; followed by 1h hands-on; with you moderating / leading the session as a whole?
  • For MITgcm I intend to rely on existing stuff (there's a lot) rather than create new material. Could just use a markdown file with links to run the 20' presentation (~like I did for session 3). Would this work?
  • How much computing resources can we expect to have available? Would be easy and fun to let attendees start this solution, either on premise or in cloud, but it would take at least 24 cores to be comfortable.

Hi @gaelforget

Pretty much, yes! I think the hands-on sessions are best done in breakout groups for each model.

For MITgcm I intend to rely on existing stuff (there's a lot) rather than create new material. Could just use a markdown file with links to run the 20' presentation (~like I did for session 3). Would this work?

That sounds fine. You know better than me! I would recommend going through a bit of the official MITgcm documentation, e.g. showing the basic equations, some of the verification experiemnts, etc.

Perhaps @thabbott can chime in about the computing resources, but I suspect 24 cores is too much...

Yes, 24 cores is too much---the machine I've set up only has 8.

Cool. Thanks for letting us know. Some follow up questions if that's ok:

  • can @fionaclerc and myself just use the instances you are setting up?
  • how much storage do you have on those instances? (a few GBs is my guess)
  • are you using aws, azure, or something else? ( likely can share $ cost if any )

  • Yes! I'll email you login info.
  • The instance has a 64 GB boot disk (with 50+ GB still free) so there's a reasonable about of storage if you want to save and play with some output
  • I'm using free trial credits on the google cloud so it's not costing me anything (but thanks for the offer anyway!)
