elbe
During my last year at the Institute for Fluiddynamics and Ship Theory at TUHH, I worked on refactoring, extending and combining my previously written GPGPU codes into one single code framework. The result is elbe – the efficient lattice boltzmann environment from Hamburg. It features 1D, 2D and 3D Lattice-Boltzmann kernels for various different physics, from the depth-averaged one-dimensional shallow water equations to three-dimensional multiphase models. elbe has already been used in a couple of Read more…

Testing the new GeForce GTX Titan
We recently tested the new NVIDIA Kepler boards for our GPGPU flow solver elbe. After initial tests on the Kepler K20 boards were very promising and led to speed-up factors of up to 2.5x (without any code modifications), we decided to purchase the new GeForce GTX Titan board to see if the consumer hardware can keep up with the professional boards. This consumer card features 2688 streaming processors, 6 GB device memory and single- and Read more…
