Are you testing on linux too ? or just in windows ? Still trying to get the same gains on windows... but that take a lof of time

I am only testing on windows. There was a small bug in the exe file I sendt out. Exe 7. I have fixed it, and noe I am preparing another checkin later today. Next kernal to be checked in is blake.

Probably a little more; and X15 can be improved a lot.
Bitslice it if you must. That will help you remove the memory issue. Checked in a small boost by using the perm instruction in whirlpool, but I think I have to rewrite the shared mem part to get 1/8th the memory reads.

Checked in a small boost by using the perm instruction in whirlpool, but I think I have to rewrite the shared mem part to get 1/8th the memory reads. Bitslice would mean NO memory reads. For 750ti: With ccminer v7 from DJm34 I have an average of: x11 = 2605 KhashWith ccminer by SP_ release 8 I have an average of: X11 = 2800 KhashThat's a 195 Khash average difference. It wont make me any richer but it is always welcome ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif) ccminer by SP_ release 8 seems to have a few bugs though. When you proceed with ctrl+c, most of the times ccminer will crash. Also when you are asked to terminate the batch job whether you say Y or N yields the same result: ccminer is closed.

By the way, any intentions on including and perhaps improving m7 algo in ccminer by SP_ releases?

Some of the bugs have been removed in the the Tvpouvet release that I forked. I will probobly refork. My focus is on the kernals, and only 50% of the kernals of x11 have been modded in the opensource.
I just recompiled with yesterdays NVIDIA driver (344.75) There seems to be a hashincrease on the 750ti of around 30KHASH.

EDIT: Just looked at Echo again. Quite well done, I tip my hat.
Instead of doing 10 rounds of echo, I do 9.25 rounds. This is because most of the first round is done on constant input. But someparts of round2 can also be precalculated... More boost is expected. To be continued.

No improvement with GTX 970 whatsoever over 1.4.9. Or maybe there was no such intended?

Kernals are beeing merged up to the head branch by tvpouvet. 1.4.9 and this mod based on 1.4.6 share the same optimalizations. There is a small difference though. 1.4.9 has improved the throughput settings in the kernals. I need to do a refork, and redo launchbounds tweaks for 1.4.9.

So it means you'll make use of his API too? I'm busy writing a .NET app that monitors your cudarigs with his API, with detailed stats etc, so that would be nice for comparisons ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

yes, When I do a refork, only some of the kernals will be different. On github alot of good changes and bugfixes have been done in 1.4.9. API support as well. Makes it worth the upgrade
