Abstract: This talk will focus on a number of computational issues arising from the use of adaptive methods and uncertainty quantification on large parallel computers. The context is provided by recent work on quantifying volcanic hazard risk over an entire jurisdiction, but the computational methodologies developed are applicable to a large class of problems characterized by the solution of complex partial differential equations using numerical discretization. We describe efficient methods for data management for adaptive computing on distributed memory platforms. The talk will also highlight the crucial role of adaptivity in making these computations feasible.
