Project description
Employing exascale systems to quantify uncertainties
Uncertainties in complex systems have long posed a significant challenge in the field of engineering. One potential solution to address this challenge involves harnessing the immense computational power offered by exascale systems. In this context, the EU-funded ExaQUte project aims to leverage the capabilities of exascale systems to conduct computational simulations. Its objective is to establish a cutting-edge framework for uncertainty quantification and optimisation under uncertainties. To achieve this, the ExaQUte project will employ a multilevel Monte Carlo approach, enabling the quantification of a vast number of stochastic variables. It will also integrate state-of-the-art dynamic task scheduling technologies with space-time accelerated solution methods. This integration aims to optimise the efficient utilisation of exascale systems.
Objective
The ExaQUte project aims at constructing a framework to enable Uncertainty Quantification (UQ) and Optimization Under Uncertainties (OUU) in complex engineering problems using computational simulations on Exascale systems.
The stochastic problem of quantifying uncertainties will be tackled by using a Multi Level MonteCarlo (MLMC) approach that allows a high number of stochastic variables. New theoretical developments will be carried out to enable its combination with adaptive mesh refinement, considering both, octree-based and anisotropic mesh adaptation.
Gradient-based optimization techniques will be extended to consider uncertainties by developing methods to compute stochastic sensitivities, This requires new theoretical and computational developments. With a proper definition of risk measures and constraints, these methods allow high-performance robust designs, also maximizing the solution reliability.
The description of complex geometries will be possible by employing embedded methods, which guarantee a high robustness in the mesh generation and adaptation steps, while allowing preserving the exact geometry representation.
The efficient exploitation of Exascale system will be addressed by combining State-of-the-Art dynamic task-scheduling technologies with space-time accelerated solution methods, where parallelism is harvested both in space and time.
The methods and tools developed in ExaQUte will be applicable to many fields of science and technology. The chosen application focuses on wind engineering, a field of notable industrial interest for which currently no reliable solution exists. This will include the quantification of uncertainties in the response of civil engineering structures to the wind action, and the shape optimization taking into account uncertainties related to wind loading, structural shape and material behavior.
All developments in ExaQUte will be open-source and will follow a modular approach, thus maximizing future impact.
