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 ...

How could a bitcoin pool hold[water?  Wouldn't the tourists wade in and grab them?       --scryptr

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

its all a good thing smolen ...

Haha, I'd be spending more than a few satoshis on ladyboys there!

hahaha - i would definitely be in ... just need to get a an address and start 'saving' ...

never been to hong kong and the missus and i would be way too eager to get out of australia for a holiday ...

as for the ladybois ... well - im leaving that one to you wolf ...

cudaminer conference ... when is that bomba?

I bitsliced R and E and Einv.

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.

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 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%
