UM-Bridge Workshop 2022
UM-Bridge is an easy to use and language-agnostic software interface for coupling Uncertainty Quantification (UQ) methods to numerical models. It enables containerization of models for portability and reproducibility as well as access to cloud platforms. For details on UM-Bridge and a library of ready to run UQ benchmarks, see UM-Bridge documentation.
This workshop has the following goals:
- Teach how to use UM-Bridge
- Initiate new collaborations between UQ and model experts
- Advance the UQ software ecosystem through common interfaces, unified benchmarks and access to cloud-based HPC
Talk Recordings
Some of the talks are available online: Recordings
Organizers
- Anne Reinarz anne.k.reinarz@durham.ac.uk
- Linus Seelinger linus.seelinger@iwr.uni-heidelberg.de
Time and Location
The workshop will be held online and span two days:
- Monday, December 12, 10:00 - 18:00 CET
- Tuesday, December 13, 10:00 - 18:00 CET
- For American time zones, we offer additional late sessions
We plan to use gather.town as our online platform; details are TBA.
Registration
Registration is available through the registration form, up to the limit of 50 participants.
Introduction session
We will have a short session where each participant may (optionally) introduce themselves and say a few words about their research interests and current projects. This is supposed to help in finding interesting discussion partners. If you’d like to participate and show something, please send me up to 3 PDF slides until Saturday (Dec. 10) to linus.seelinger@iwr.uni-heidelberg.de; I will compile them in a single document to avoid delays in between.
Prerequisites
For practical exercises, you will need working installations of
- docker (available at docker.com)
- Python
Schedule
Times below in CET (GMT+1).
