Hydrodynamic Stability Without Eigenvalues
TL;DR: A reconciliation of findings with the traditional analysis is presented based on the "pseudospectra" of the linearized problem, which imply that small perturbations to the smooth flow may be amplified by factors on the order of 105 by a linear mechanism even though all the eigenmodes decay monotonically.

TL;DR: The work of the community to prepare for the challenges of exascale computing is described, ultimately combing their efforts in a coordinated International Exascale Software Project.
MultiMATLAB: MATLAB on Multiple Processors
Anne E. Trefethen,Vijay Menon,Chi Chang,Grzegorz Czajkowski,Christopher R. Myers,Lloyd N. Trefethen +5 more
TL;DR: A system is described that enables one to run MATLAB conveniently on multiple processors using short, MATLAB-style commands, potentially useful for education in parallel programming, for prototyping parallel algorithms, and for fast and convenient execution of easily parallelizable numerical computations onmultiple processors.
Proceedings ArticleDOI
MultiMATLAB Integrating MATLAB with High Performance Parallel Computing
Vijay Menon,Anne E. Trefethen +1 more
TL;DR: This work presents a MultiMATLAB architecture that provides performance on multiprocessors while maintaining the functionality and usability of MATLAB, and discusses a general Multi MATLAB architecture and two implementations built upon MPI.
Journal ArticleDOI
Spectra and pseudospectra for pipe Poiseuille flow
TL;DR: In this article, numerically computed spectra and pseudospectra are presented for the linear operator that governs the temporal evolution of infinitesimal perturbations of laminar flow in an infinite circular pipe at Reynolds numbers 1000, 3000 and 10 000.
