SEAVEA Hackathon and Applications Meeting

The second SEAVEA Hackathon is taking place on 8-9 December 2022. The two-day Hackathon on Verification, Validation and Uncertainty Quantification (VVUQ) for HPC simulations will focus on the SEAVEA toolkit (SEAVEAtk), which facilitates VVUQ for applications irrespective of their source domain. The two-day Hackathon will take place in-person at University College London. If you are interested in making your simulations more robust and your results more credible, then do not miss it and register now.

The Hackathon will allow you to interact with our SEAVEAtk experts, who will help you apply your choice of SEAVEAtk tools on your own codes and applications. And if you already are a SEAVEAtk user, then we will have support on hand to help you add more rigorous VVUQ to your application. The toolkit provides a variety range of tools to:

  • create VVUQ procedures (EasyVVUQ),
  • to facilitate the creation of surrogate models for multiscale simulations (EasySurrogate),
  • to automate the complex workflows emerging from these procedures (FabSim3),
  • to enable the efficient execution of large numbers of jobs on computational resources (QCG Pilot Job Manager),
  • to provide convenient means to use HPC facilities for users (QCG-Now) and user-developers (FabSim3 and QCG-Client),
  • to make creating coupled multiscale simulations easy, and to then enable efficient Uncertainty Quantification of such models using advanced semi-intrusive algorithms (MUSCLE3),
  • to perform surrogate modelling using Gaussian Processes (MOGP).

The Hackathon will be structured as follows:

Applications Meeting – 12 December 2022

You are invited to join the SEAVEA applications meeting on 12 December 2022 at University College London. Within this applications meeting, which will be a fully hybrid event, we will initiate a discussion on topics of major societal importance, including climate change, medicine and energy production, conducted at ever increasing scales and scope. Moreover, we invite speakers from diverse backgrounds to present the context of the emerging exascale computing infrastructures and the potential of quantum computing.

However, fundamental principles of scientific investigation must be widely enforced to ensure the reliability of and confidence in the results generated. This hinges on our ability to (i) validate (V) them, normally against experimental observations, but sometimes compared to “gold standard” numerical results; (ii) verify (V) them, to ensure that the correct mathematics is used, and (iii) equip the output data with meaningful bounds on errors which come from rigorous uncertainty quantification (UQ).

We also invite everyone, speakers and participants alike, to take part in discussions around these central themes, and to contribute towards specific strategies to improve the quality and uptake of VVUQ in a HPC simulation context. These strategies will then form a backbone for the activities in the SEAVEA project (and beyond) over the coming year.

Please register for the meeting here no later than Tuesday 2 December.
