Description Vedran Miletić 2015-12-21 13:02:27 UTC 
For teaching and demonstration purposes it would be cool to have emulated fp64 arithmetic on low-end Evergreen and Northern Islands chips which don't support it (e.g. Caicos). However slow it might end up being, it would be really useful to have it at least for teaching GPU computing.
