Scaling finite difference methods in large eddy simulation of jet engine noise to the petascale: numerical methods and their efficient and automated implementation
… method and the Schur complement method. Algorithmically, these solvers force a trade-off between numerical accuracy and parallel scalability. Programmingwise, implementing them for each of the three coordinate directions is tediously repetitive and error-prone. ^ In this study, we attempt …

Scalable parallel tridiagonal algorithms with diagonal pivoting and their optimization for many-core architectures
… to no pivoting. Meanwhile, conventional pivoting algorithms are sequential and not applicable to GPUs. In this thesis, we propose three scalable tridiagonal algorithms with diagonal pivoting for better quality of solutions than the state-of-the-art GPU tridiagonal solvers. A SPIKE-Diagonal …
