Some nice work there done in the other forks. I Will be away for a while so will take some time before I test and merge. I see some more possible speedups in whirlpoolx as well.
all good sp ... if its a holiday - njoi mate ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) ... #crysx

Rough idea - use lookup tables to pick up only linear independent bits and regenerate the rest by boolean matrix multiplication.
Small R and E lookup tables, the only source of non-linearity in whirlpool, take only 4*16 bits and could be implemented via uint64_t shift, without any memory access. Yeah, chatting with myself here ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

Of course I gave you bad advice. Good one is way out of your price range.

(level 1 cache 1 cycle per read) The current opensource miner do a lookup for every 8 bits. By increasing each lookup to use 11 bits I reduce the number of table lookups 25% 11bits will also fit into the 64KB 750 sharedmem limit wich is 64kb. I call it the X-box. Precalculated, but faster.

I bitsliced R and E and Einv.
No actual code yet, bitsliced whirlpool lives in tables in memory. Just above 2000 commands per round, 2 hashes in parallel for 32 bit operations ![Sad](https://bitcointalk.org/Smileys/default/sad.gif) Have to write codegenerator. The 980 has 96KB of shared mem. (level 1 cache 1 cycle per read) The current opensource miner do a lookup for every 8 bits. By increasing each lookup to use 11 bits I reduce the number of table lookups 25%
11bits will also fit into the 64KB 750 sharedmem limit wich is 64kb.
I call it the X-box.
Precalculated, but faster.
Cool!
