-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 There is no master plan I know of. For my MSc project with Johan Jansson at KTH last year I implemented GPU assembly and solve using DOLFIN. There are 2 backends: a native CUDA one and one using the cusp library from NVIDIA. I'm currently trying to get my code in shape and working with the current dolfin-dev to publish in a branch on launchpad (lp:~florian-rathgeber/dolfin/gpu-backend). The code currently in there is broken, I had pushed it to show the CMake problems I was seeing. Hopefully I can push something working soon.
If you want to read up on the background my MSc thesis is probably a good start: http://www.nada.kth.se/utbildning/grukth/exjobb/rapportlistor/2010/rapporter10/rathgeber_florian_10106.pdf I don't know how much time I will have to maintain this, but I thought it would be useful to have something out for people to play with and show there is work in this direction in the FEniCS community.
