Dr Derek Groen of Brunel University London presents the VECMA Toolkit (VECMAtk, www.vecma-toolkit.eu). 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)
