A Parallel Solution-Adaptive Method for Turbulent Non-Premixed Combusting Flows
A parallel adaptive mesh refinement (AMR) algorithm is proposed and applied to the predictions of turbulent non-premixed compressible combusting flows for both two and three space dimensions. The parallel solution-adaptive algorithm solves the system of partial-differential equations governing …

ADMM Based Methods for Time-Domain Decomposition Formulations of Optimal Control Problems
… (PDE)-constrained optimization problems. The solution of such optimization problems is computing time and memory intensive. TDD formulations split the time-dependent PDE into coupled subdomain equations and introduce potential for parallelism and global memory reduction. This thesis tailors …

Monolithic and partitioned Rosenbrock-based time integration methods for dynamic substructure tests
… cases and partitioned methods with staggered and parallel solution procedures for linear and nonlinear cases. Initially, the Rosenbrock integration methods endowed with one stage to three stages are introduced and their applicabilities to second-order systems are investigated in terms of accuracy, …

Recursive Bayesian Filtering Through a Mixture of Gaussian and Discrete Particles
Conventional solutions to nonlinear filtering problems fall into two categories, deterministic and stochastic approaches. While the former is heavily used due to low computational demand, approximation error is tied to their initialization, which causes difficulty during long term application. The …

Boundary method-based domain decomposition on multiprocessors
… efficient method has been developed for the fast solution of the boundary problems of Poisson's equation on irregular as well as regular domains. The method, called the boundary method-based domain decomposition or BMDD, combines the attractiveness of the domain decomposition technique in parallel …

Smoothing Particle Hydrodynamics parallel implementation for numerical modelling of solid-fluid interactions
In this work is presented an effcient parallel implementation of a Lagrangian mesh-free method based on the Smoothing Particle Hydrodynamics technique to analyse the behaviour of solids and fluids. The proposed solution makes use of different techniques to improve the computational complexity of …

MR-CUDASW - GPU accelerated Smith-Waterman algorithm for medium-length (meta)genomic data
… Accordingly, this algorithm is the first highly parallel solution that has been specifically optimized to process medium-length nucleotide reads (DNA/RNA) from modern sequencing machines (i.e. Ion Torrent). Results show that the software reaches up to 82 GCUPS (Giga Cell Updates Per Second) on a …

Domain decomposition preconditioners for higher-order discontinuous Galerkin discretizations
… solver able to take advantage of the massively parallel architectures of modern day supercomputers. A higher-order hybridizable discontinuous Galerkin (HDG) discretization combined with an implicit solution method is proposed as a means to attain engineering accuracy at lower computational cost. …

Adjoint based solution and uncertainty quantification techniques for variational inverse problems
… results fit the physical measurements.The solution procedure is computationally expensive since it involves running the simulation computer model (the emph{forward model}) and the associated emph {adjoint model} multiple times. In practice, our knowledge of the underlying physics is …
