| Abstract Scope |
Tasmanian is library for Uncertainty Quantification developed at Oak Ridge National Laboratory, with focus on sparse grids surrogate modeling, Bayesian inference and optimization. The library has been deployed in many applications ranging from surrogates for melt-pool shape geometry, to plasma-material interactions and magneto-hydrodynamics in plasma physics, to fracture mechanics in solids. Tasmanian offers a wide range of tools that address problems of different level of smoothness of the model outputs of interest with respect to the model inputs, from very smooth to discontinuous, and different computational complexity from a few minutes to hours or days at a cluster computer. The latest development in Tasmanian allow us to deploy our tools on exascale supercomputers, including the utilization of extreme concurrency and GPU accelerators. In this talk, we will present some of the new results with specific focus on multi-physics simulations for additive manufacturing and plasma physics. |
