You need a double precision gpu to do this project on a gpu. Single precision is not used. A few other projects may be able to be done on it instead. Doesn't expecting the unexpected make the unexpected the expected? If it makes sense, DON'T do it. |

There are other threads about this subject, but on the hardware side if you are running cuda you need a GTX260 or up, if you are ATI based you need 48XX or up. If you are thinking to purchase hardware for this project, get ATI equipment as their cards are way faster than cuda. As to why use double precision? The projects deals in astronomical distances, and single precision does NOT give the accuracy provided. Cheers |
