Accepted: Biomolecular electrostatics solver using Python and GPUs

Surface charge plot on a lysozyme molecule, obtained using the PyGBe code.

Submitted: 20 September, 2013. Accepted: 24 October, 2013. This paper presents a study of the effect of solvent-filled cavities and Stern layers in a biomolecular electrostatics solver based on a boundary integral formulation. The tool for this study was the PyGBe code: a solver for biomolecular electrostatics using Python, GPUs and boundary elements. To determine... Continue »

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 »
