Re: [ESPResSo-users] GPU Lattice Boltzmann

[Georg Rempfer]

Hey,

hardware wise you need an NVIDIA graphics card with compute capability >= 2.0. I think you would have a hard time finding a card that only has compute capability 1.1 these days, so that is not a serious constraint. The more memory the better of course. As for the software, you need the CUDA toolkit and matching drivers to be installed on the machine. Both of those you can get from the NVIDIA website (https://developer.nvidia.com/cuda-downloads) or from your distribution's repositories.

Greetings,

Georg

Hi,

A list of all CUDA capable GPUs is here:

You can find the instructions to get started with CUDA (what is needed
for ESPResSo on GPUs) in the documentation of nvidia:

Can someone please give me some information about what GPU is needed as a minimum? What libraries is the implementation referring to?
