Pallas, can you  rewrite this groesl-256 implementation to a groestl-512 and add it to sgminer (x11,x13,x15).?

Yes, that makes the game damn addictive.
Look, you told us about wide tables, great idea, but to skip sboxing with it couple more inches deeper inside AES is needed

@wolf0 do you have anything better than the neocrypt kernel u leaked on feathercoin thread?  I am getting 278KHs on 7950 and 295 on 280x

Just wanted to say I've tried applying some of the tricks I learnt working on whirlpoolx to the groestl kernel, but it's not so simple.
This kernel is much bigger in size so you can't just copy some good lines of code and it runs faster. Furthermore some of the optimizations I made in the past, make it more time consuming to apply some apparently simple hacks. Wolf0 I'm sure you know what I mean ;-)
Still there is room for improvement, I have some ideas, but the question is: when the profit is gone, and the fun is gone, is it still worth?

Wow! may I have new Neoscrypt kernel, 7950 working hard just doing 278KHs with your older kernel!

Looking ... 1160/1500 I have modded card a bit for better cooling

Another trick, not for speed, but for cleaning the code - when you want to postpone sboxing of byte, put preimage of zero (0x81 in Whirlpool) there.

That's some truly slick updates!

I was indeed planning to do full AES round without t-tables as the amount of masks are nonsensical.
I had the impression the SALU was immensely updated for Tonga given it takes much more VGPRs on the analyzer.

I wonder how to trick the CL compiler in emitting this code.

But most importantly, what are they waiting to just make an AMD_GCN_swizzle extension!?

I'm interested in knowing the hashrate of R9 285 and R9 Fury X cards, anybody?

Nothing new in the groestl+groestl area, but I've worked a bit on the groestl+sha variant (myr-groestl for myriad, digibyte, saffron, etc.).
Tahiti is a mess, but I could easily push hawaii over 60 Mh/s, keeping the kernel compatible with the old miners.

the diamond.cl  is missing on the download
i only see groestlcoin-v1.cl

or must we just rename to diamond ?

so i rename to diamond.cl
but no change in my speed i have 4.7 mh on r9 270  sgminer 4.1.0

i guest groestlcoin-v1.cl is not for diamond, i ve got a lot rejected shares
