Pi-Yueh Chuang at GTC 2016


At this year's NVIDIA GPU Technology Conference, PhD student Pi-Yueh Chuang presented the work "Using AmgX to Accelerate PETSc Codes." AmgX is an NVIDIA library that provides sparse linear solvers, smoothers and preconditioners on GPU devices. Pi-Yueh presented his work to couple AmgX with our fluid-flow solver, PetIBM. This code solves the Navier-Stokes equations on Cartesian... Continue »

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 »

Validation of the PyGBe code for Poisson-Boltzmann equation

The PyGBe code solves the linearized Poisson-Boltzmann equation using a boundary-integral formulation. We use a boundary element method with a collocation approach, and solve it via a Krylov-subspace method. To do this efficiently, the matrix-vector multiplications in the Krylov iterations are accelerated with a... Continue »
