Yesterday the admin announced a new subproject that will run on GPUs ...
QuoteGPU72 new subproject (pre-alpha)
GPU72 is a subproject for GPU Trial Factoring of Mersenne Prime. The project will be run on opencl for AMD and Nvidia cards on 64bit only.
There is still some further processing in creating all the server stuff.
No new workunits ready at the moment though.
GPU72 workunits are available now.
Wowzer, I ran just a few tasks to see how they go, talk about working the GPU, first time I have seen the gtx 970 screaming with fan and temps in 80s.
Gee, no other project really works the card as hard as this one lol.
Cheers
The GPU72 application has now been renamed to TF (Trial Factoring).

Unfortunately, all TF applications need to be renewed, which is why all results from the GIMPs server will be rejected after the 31st except mfakto apps earlier.
