ok, I have released the source of the x15 ccminer.
It can be found here:
https://github.com/djm34/ccminercompilation on windows takes forever (sorry for that).
It should compile on linux (I fixed the Makefile.am), if anything is missing let me know...
To run x15 "ccminer -a x15"
as previously said, it is far from perfect (gpu usage rather low around 80%, so there are room for optimisation... and exceptionally the 780ti runs at 74°C).
I get at the moment (started on the previous compilation):
1467MHash/s for the 750ti
2900MHash/s for the 780ti (on supernova...)
Compiling now...... Then on to testing. Thank you very much for your efforts, and for sharing!!
