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.

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

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.

Bitslice would mean NO memory reads.

For 750ti:

With ccminer v7 from DJm34 I have an average of:
x11 = 2605 Khash

With ccminer by SP_ release 8 I have an average of:
X11 = 2800 Khash

That's a 195 Khash average difference. It wont make me any richer but it is always welcome Cheesy

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.

Maximum on the 980, limited by 1.2500v, voltage limitations of the reference cards Sad

Targeting 10MH/s X11, keep pushing  Cool

Disabling SLI things go higher, will print screen trying to hit 10MH/s.

wow Smiley good game, didnt check blake512 for the moment, trying to fix x13 weird behavior during benchmark

but i was able to see the improvements on windows too with the previous commit

EDIT: + 10KH also with blake on the 750 ti

Faster blake (nist5, quark,x11 etc.).

http://www.filedropper.com/release8

fixed bug in release7 (unvalid nounces) (the bug was only present in the exe, because an old file was linked in instead of the latest)

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.

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 have checked in some more performance improvements. I moved the precalc table in echo from constmem to the instruction cache. Improved registers/launchbounds on shavite.

The 980 is now around 400KHASH faster than the release 6. on stock clocks.(x11).

Here is the link:

http://www.filedropper.com/release7

Nice, 9MH/s with 185+ on 980 GPUs.
10MH/s with extreme overclock GPU at 300+ and overvolted.

750Ti boost to 2.9MH/s with 135+ GPU 460+ MEM.

Cheers

Possible small optimization at the end of cuda_echo_round:
Code:
	for (int i = 0; i<15; i += 4)
{
W[i] ^= W[32 + i] ^ 512;
W[i + 1] ^= W[32 + i + 1];
W[i + 2] ^= W[32 + i + 2];
W[i + 3] ^= W[32 + i + 3];
}
W[15] ^= W[47] ^ 512;
(we don't need more than 16)

Thanks, it works.

   for (int i = 0; i<15; i += 4)
   {
      W ^= W[32 + i] ^ 512;
      W[i + 1] ^= W[32 + i + 1];
      W[i + 2] ^= W[32 + i + 2];
      W[i + 3] ^= W[32 + i + 3];
   }

is enough.

Indeed, +15kH on the 750 Ti (2ms improvement on your repo, its the biggest optimisation you have made on a single algo, was 0.5 before, i will pick it for the 1.5.0)
on mine, i get +9 KH (2791 vs 2800KH in benchmark mode) but i didnt take the launch bounds change for the moment...
39.171ms before, 38.522ms before = 0.65ms on mine, enough for me (but not fully comparable)
EDIT: but on windows :// seems to be lowered, investigating...

In addition to the launchbound change, did you remember to go from 256 to 320 threads when calling the kernal?. The launchbound will force the compiler to use 64 registers. We get more spills to memory, but it seems to run faster.

the problem is that the throughput is set to be fast on the 980 in the source version. download the 1.4.9 source and replace the file:

cuda_x11_echo.cu from my fork

you should get a small boost in x11. On quark I have optimized bmw and blake a tinybit

1.4.9 with the intesity parameter is found here:

 https://github.com/tpruvot/ccminer

sp your older ccminer  and im really pushing it. looking forward to your new one.  Smiley
the fastest hashing is 1.4.6
