Boost in x11,x13,x14,x15,x17 comming soon. I finally managed to do the pointer tweaking right in the AES implementation. This removes some assembly instructions for every table lookup in the SBOX.
// inline asm
bfi.b32 %r234, %r18, %r527, %r528,%r569;
// inline asm
ld.u32 %r576, [%r234];
// inline asm
with valid hashes...
Very nice! Can't wait to try it. I was a little bit bored with all this offtop discussions about pools and markets, so your post is a breath of fresh air  |

Submitted a teaser you can test. github. Just a small speedup. If I replace all the sharedmem lookups the compiler is increasing the register count and hashrate is dropped. Need to find a way to tweak the compiler so that it generate the optimal code.

The people who work for the pools create fake acounts on the bitcointalk forum and other forums. They work in teams of 2-3 people, and sometimes they can control all the users.
My feeling is it's also true for coins themselves. Which makes the research that much more difficult. And picking the wrong coin is IMHO much worse than not making the maximum profit. well if everyone think like you, you won't make any profit at all... because seen like that, I am not sure there is any reason to buy coins... I don't agree with you. Maybe I wasn't clear, English is not my first language. When I put my rig on nicehash or miningrigrentals, I effectively rent it to someone who has done the research and pays me for the hashrate. Similar to what cloud mining companies do. We are both doing half the work: I manage and maintain my rig, the buyer sifts through all the coins and finds one he believes in. He invests a lot of time, I invest a little time and some money for the hardware and power bill, and we split the profit. This is cooperation. What I meant is, it's better to split the work and do both parts right, than try to do everything and do it badly because I don't have enough time. |

So again you really don't maximize your profit, you just settle for a minimum which is probably a lot lower than what you could achieve alone after having done some research... |

This is SP_artaaaa!!  well this is a Marathon to try to explain to new comers to crypto than there is a little more to crypto than just plugging their card to a pool and expecting money... it is called mining not milking... so there is some prospection involved... |

Cryptocurrencies started as an ideal, it had a purpose, but it just went down the shithole of profit 'only'. Everyone wants capitalism to work but they never take into account human factor. Its a good plan but it asks for honesty, justness & some ethics/morals. Its a sad thing people cure the symptoms not the cause. |

Its great to see that you are going out of your way to keep this just and support the dev. We can play capitalism with you for sure.  All the Best. |

All the Best. tanx sam ... very few devs will go out of their way to do these things - let alone release all the source code ( charged for or not ) ... sp is one of those that will ... so the focus is simple ... give back a percentage ( in our case 7% ) of the mining on a regular basis - which is about one day out of seven for as long as the farm is around ... if westhash DO whitelist our ip's - then the donation links will be permanent ... or at least as permanent as we are around ... we want to support the devs that support the community who support the devs ... so any ideas would be great - if we can implement them of course ... maybe start a new thread for this? ... #crysx |

This is SP_artaaaa!! Indeed. The codebase is pretty large with 30+ hashing algorithms. This meens that it's still possible to find small speedups everywhere. It just takes alot of time... A code marathon.... If you look at the first sp-mod from october 2014 the x11 was doing 6,5MHASH on the gtx 980x (scroll to the first page). In the latest Sp-mod (50+) an overclocked gtx980 will do 11-12 MHASH. That's a 70% - 85% increase of hashrate in 7 months. (free and opensource) There are other algos that have a higher increase.. Try blake... over 150% faster The problem with modern gpu's is that they change so quickly that the software developers don't have time to make optimal code before a new chip is comming. |

just out of curiosity - will you implement blake2b algo in ccminer? ...
ive been seeing a number of chats about the algo - which usually leads to new coins being created to make use of the algo ...

else.. on the other branch... multi pools config and pool failover/time switching is almost ready.
I can say it will be in my next release.. 1.6.4

Writing it in before there's a PoW using it is a waste of time; additionally, it's already there - Neoscrypt uses Blake2b, I believe. I have already optimized the blake implementation in Neoscrypt (from djm34's version). the total hashgain was around 7% on the 750ti. So the latest Sp-mod is around 7% faster than the optimized djm34 version when mining neoscrypt. |
