NSGminer v0.9.2: The Fastest Feathercoin / NeoScrypt GPU Miner

It’s executed 64 times per hash. The final XOR outside the loop is less important.

Unless you mean something you’ve not pushed, in which case never mind. If you have, then nice - my trick with the aligning the XOR worked out for you.
Well, I added it to my beta 10 days ago. You have mentioned to do bytewise XOR in uints, I have vectorised it which is also fine. Not uploaded to GitHub yet, but quite a few people use it right now. It’s well improved over the previous release in performance and compatibility. I see only a 5% decrease while switching from 14.6 to 15.7 drivers. It was much worse before (https://bitcointalk.org/index.php?topic=712650.msg13585416#msg13585416).

OH, lol, yes, that is good, but that was not what I meant! This line:
[code]
neoscrypt_bxor(&Bb[bufptr], &T[0], 32);
[/code]I’m saying I did this operation using uints.

@Wolf0 I get it. I’ve also rewritten it. The code quoted is plain bytewise, though old VLIW GPUs like it for some arcane reason.

Odd. I got my 6970 today, so I should be able to work on Cayman in a while.
-
I have managed to squeeze 520 and 500Kh/s out of my r9 290s, and up to 420KH/s on my 7950s which is more where I was expecting, all my 7970/280x are between 450 and 500KH/s with the majority being around 500.
-
I have optimised almost all bytewise parts of FastKDF. 800KH/s before with v7 beta, 820KH/s now (Catalyst 14.6) or 770KH/s (Catalyst 15.7).
-
Even with beta v7, Im floating around 320KH/s on my 7950s. I only saw a ~20-30KH/s increase.

what driver version are you using?

weird… i think that is what I am running, plain and simple -w 128 -I 16…I will check tonight
What clocks are yours set to? Im running 1110/1550 or higher…

Ill have to double check my settings but I think clocks are 1100/1600 or so.

-w 256 -I 13 -g 2 and 1050/1600 clocks on 14.7 drivers. I did see when I got home that the rig had shutdown and had issues booting back up. I reinstalled the drivers and tried -w 128. So far its slower but I’ll let it hash awhile to see what it does.

Edit miner.c and driver-cpu.c to include neoscrypt.h before miner.h, and update typedefs in miner.h to the following:
#if !(uchar)
typedef unsigned char uchar;
#endif
#if !(uint)
typedef unsigned int uint;
#endif
#if !(ullong)
typedef unsigned long long ullong;
#endif -
In the code a type is defined, that was previously defined in another part/module/file
Suggesstion:
Edit miner.h and comment out the lines defining the type ullong and uchar
Then try again.
[Edit]
Ghostlanders way is far more elegant :D -

@AmDD So I checked driver version…its reporting as 15.8 but I know I downgraded it to 14.6 rc2
also I am running at I 15 because I am under 400KH/s with I 16

NSGminer v0.9.2 released. Well optimised for any drivers. Enjoy.

Thank you Ghostlander! I am not a miner, but will send you few more FTC later on :+1:

That fixed my slow r9 290!
