Nature TechBlog: My digital toolbox

Jeffrey Perkel, Technology Editor for Nature, interviewed Prof. Lorena A. Barba about her research group's reproducibility practices and the digital tools that enable them. She talked about the group's computational research interests, their avant-garde use of digital tools and repositories to create "repro-packs," and how these allow her to share research figures freely even when part...

Submitted: "Lift and wakes of flying snakes"

Sketch of the gliding behavior of a flying snake.

Submitted: September 16, 2013. Accepted in Physics of Fluids: February 10, 2014. This paper presents a computational study of the aerodynamics of an anatomically correct cross-section of Chrysopelia paradisi, the flying snake. These animals inhabit the canopy of rainforests in East Asia, and have a very peculiar method of locomotion: they jump from tree branches, change... Continue »

How will the fast-multipole method fare in the exascale era?

Roofline model of current hardware and computational intensity of various representative algorithms.

SIAM News (Vol. 46, issue 6) has published on the front page our piece about the future of algorithms in the exascale era. This piece was written by invitation on the aftermath of a very successful SIAM Conference on Computational Science and Engineering, held in Boston last February. At this conference several minisymposia focused on... Continue »

New exaFMM paper accepted

An isosurface plot of the second invariant of the velocity gradient tensor helps to visualize the structures of turbulence.

FMM-based vortex method for simulation of isotropic turbulence on GPUs, compared with a spectral method, Rio Yokota, L. A. Barba, Computers & Fluids, in press (available online 13 August 2012), doi:10.1016/j.compfluid.2012.08.002 This paper presents the results of comparing a Lagrangian vortex method with a trusted spectral method for the simulation of isotropic fluid turbulence. The numerical engine of the vorticity-based fluid... Continue »
