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 »
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 »
Vorticity field in the wake behind a snake cross-section at a Reynolds number of 2000 and 35-degrees angle of attack.
These animations show the vortex wake behind a snake cross-section (two-dimensional profile), obtained with full Navier-Stokes simulation. The solver is an immersed boundary method that uses GPU hardware, cuIBM (open-source under the MIT license). The cases shown vary in Reynolds number (Re=1000, 2000) and angle... Continue »
PhD student Christopher Cooper presenting in the "CUDA Research Fast Forward" event at the NVIDIA booth in the SC'11 conference.
Background The Boston University Center for Excellence and Innovation in Teaching (CEIT) offers a rich program of Teaching Talks (focused on pedagogy) and Teaching Tech Talks (focused on technology use). The Spring 2013 program included talks on course design, using learning management systems, group work in the classroom, etc. I was invited to host a CEIT... Continue »
