You are invited to join an online seminar on VECMAtk and the impact of uncertainty on predictions of the CovidSim epidemiological code, which takes place on 10:00UK/11:00CET, Friday 16 April
This seminar covers two related subjects:
1) Speaker: Dr Derek Groen, Brunel University London
The first part of the seminar introduces the VECMA Toolkit (VECMAtk). The toolkit enables automated Verification, Validation and Uncertainty Quantification (VVUQ) for complex single- and multi-scale applications that can be deployed on emerging exascale platforms and provides support for software applications for any domain of interest. 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),
- and to make creating coupled multiscale simulations easy, and to then enable efficient Uncertainty Quantification of such models using advanced semi-intrusive algorithms (MUSCLE3)
2) Speaker: Wouter Edeling, Centrum Wiskunde & Informatica (CWI)
The second part of the seminar covers an application of VECMAtk. Epidemiological modelling has assisted in identifying interventions that reduce the impact of COVID-19. The UK government relied, in part, on the CovidSim model to guide its policy to contain the rapid spread of the COVID-19 pandemic during March and April 2020; however, CovidSim contains several sources of uncertainty that affect the quality of its predictions: parametric uncertainty, model structure uncertainty and scenario uncertainty. Our research, recently published in Nature Computational Science, examined parametric sensitivity analysis and uncertainty quantification of the code using components of VECMAtk.
