New CUDA Research Center at GW
NVIDIA names GW a new CUDA Research Center, in recognition of the research trajectory of Prof. Lorena Barba. The announcement reads as follows. The CUDA Research Center at the George Washington University in Washington, DC, recognizes the research trajectory of Prof. Lorena A. Barba. With a background in mechanical engineering and aeronautics, and a few... Continue »

PyGBe: Python on the surface, GPUs at the heart. BEM solver for Electrostatics of Biomolecules
Poster presented at the GPU Technology Conference, March 2013, San Jose, CA.
It presents the PyGBe code (pronounced 'pig-bee'), which solves the linearized Poisson-Boltzmann equation using a boundary element method, BEM. The underlying dense systems are solved using a Krylov-subspace method, accelerated with... Continue »
Weak scaling of parallel FMM vs. FFT up to 4096 processes
This figure shows the weak scaling of a parallel FMM-based fluid solver on GPUs, from 1 to 4096 processes. The FMM (fast multipole method) is used as the numerical engine in a vortex method fluid solver, simulating decaying isotropic turbulence. The reference method for this application... Continue »
Validation of the cuIBM code
We have developed a Navier-Stokes solver, called cuIBM, to simulate incompressible flows using immersed boundary methods. This document provides background on the numerical methods implemented in the cuIBM code framework and evidence of the validation exercise carried out by the authors. The code provides... Continue »
