could you please link the forum thread instead of the .cl file directly? this is the link: https://bitcointalk.org/index.php?topic=779598.0there is some important information on there, which can be necessary for some people to make the kernel work properly. thanks! |

thanks danbi.
a couple questions:
do you suggest to set a change address even for wallets which don't make a lot of send transactions?
are the minting transactions creating such additional hidden change addresses as well?

Complete mining newbie reporting in, with some questions.
Decided to dabble in xmr mining a bit, to support the network, and put any hypothetical earnings into the dev address, as per smooth's suggestion. Getting started on Amazon's EC2 as well, but also wanted to see if I can put my Macbook to use... here's the result:
I might as well turn it off, right? I'm adding about 40 H/s, which is for all practical purposes negligible, correct?
just don't expect it to pay the electricity it consumes, not even if you sell at 3x the current price ;-) |

So, it's for sure then that wolf0 is violating the GPLv3 by not providing source code even when he is distributing the binaries? Great... what a fucking asshole. I really hope one of the sgminer or cgminer devs sue him.
Build your own miner and stop stealing, wolf0! Or try being honorable for once and stop violating software licenses.
The thing is, even if he violated GPL, it will be a moot point as soon as someone released an equivalent open source miner, which isn't really hard to do given all the information we have from this thread, and the fact that AMD even posted their own optimization guide. http://developer.amd.com/tools-and-sdks/opencl-zone/amd-accelerated-parallel-processing-app-sdk/opencl-optimization-guide/#50401334_pgfId-448804So instead of all the useless whining about wolf, which will definitely not change his mind, maybe people should get to work. true, but don't expect that guide to help you much. optimizations are much more subtle and you need to know programming and the algorythms pretty well. |

Congratulations Pallas.
Do you have it on Github already?
Thanks. No git yet. I was thinking it's not necessary for a single file, but now there are bins and maybe multiple versions so I may end up doing it. congratulations excellent optimization, but what about the other algorithms I did work on other algorithms too (x11 components, m7 and others) but nothing ready for publication. I'd need more time and lower kilowatt hour cost in order to go ahead :-) I understand that all miners are written C ++, and why not in C #, it is a bit faster than the C ++ Most miners are written in plain C but it doesn't matter that much unless you are mining with the CPU (still there is a good deal of assembly on some algorithms). GPU code is opencl or cuda instead. |

I don't really think it's possible to create a human mineable coin. The problem is you need a PoW algorithm which is hard for bots to solve but easy for humans to solve, but it also needs to be easy for computers to verify the solution. There is no easy way to meet those requirements. The problem space would have to be so huge that a bot wont have any chance at finding a solution by randomly searching for one, but it should be solvable by applying creativity and logic. For example when a programmer is faced with a problem he must apply creativity and logic to write an algorithm which can solve the problem. If he were to randomly try every possible algorithm he would never find a solution, but by applying human reasoning skills he is able to write an algorithm capable of solving the problem. That is the sort of PoW problem required to make a human mineable coin.
what about a captcha type thing? thats easy for humans to solve Captcoin |

two weird things:
- my wallet did not mint a single block for 6 days (usually it was 1/2 a day)
- cpu usage is much lower recently
may it has to do with the blockchain problem? is there a way to check if it's minting, other than "unlocked_until"?

Guys the mh/s and the GPU clocks you are getting on R9 290x's ,,,,,, do your card;s have standard cooling fans  I ask because i cant get any where near some of those high GPU clocks, the very max i can get with stock cooler's is 1020 so how am i seeing some ppl get clocks as high as 1050;s + cheers What's your room temperature? is the case well cooled? I use a big fan blowing from the front of the case thru the cards. And all as open as possible. My GPU temps are 78 stable do i need to have lower temp to reach like 1040 GPU engin clock ? not in general, but the gpu may throttle because the fan if already at max speed. did you check the actual gpu clock to be what you set (> 1020)? |

Let's view PPC chart http://coinmarketcap.com/currencies/peercoin/After they release new wallet in android. I'm learning dev app in android, I'll free to join DMD wallet project . We need to make something for DMD, to make it's more popular. I've already compiled the headless wallet on arm and it works on android. The interface is missing of course. We discussed this recently (should it stake? full blockchain? fork bitcoin opensource android wallet? etc.). |

unfortunately there is a lot of people who need to take it out by badwording and offending on forums, because they can't in real life.

Haven't tried it yet....but do you have Linux binaries? I could try to make a linux version, not sure if I will do it with static libs. EDIT : getting the git files, configuring and compiling work perfectly, no need to provide binary git clone https://github.com/noncepool/cpuminer-yescrypt.git
cd cpuminer-yescrypt
./autogen.sh
./configure CFLAGS="-O3 -march=native"
make That makes it much slower.......you can use ./configure CFLAGS="-O3" CXXFLAGS="-O3" but its no different in speed. I believe CXXFLAGS is not used. I've tried the most aggressive CFLAGS and I get a very small boost. Still intel much better than amd. |

The dashboard on danbi's pool shows we're hashing away.
Does this mean we lose whatever mining power we pointed to it for now?
yes send ur miners towards http://multipool.bit.diamonds/there lot possible algos u can use Thanks. The problem is that I'm at work without access to rigs. Will have to wait till I get home tonight. Just an fyi - I use Teamviewer (google it) - it is free and allows me access to my rigs no matter where I am. or simply "byobu_enable" on linux ;-) |

Ok - pointed my miners to the scrypt multipool until all fixed.
if you have a gpu rig, better use x11 or nist. |
|
|

that one is already in my mod (though at the moment it is for diamond only) if you want the speedup for groestlcoin you will need to copy diamond.cl and rename it groestlcoin.cl Edit: It seems I never pushed the changes though to github.... Will update when I get off work. That groestl actually slowed down X11 a little bit for me until I modified it. Yes, some modifications are needed in order to work best on x11. |

a 6 years old i5 runs almost as fast as a new fx.
surely there is room for improvement on amd cpus.
I noticed minerd wasn't that awesome for AMD CPU's. My Phenom X3 (Unlock 4th core) doesn't do that well. Not trying to hate on amd, but thier cpus are kinda crap compared to intel speeds and standards. I agree that hashrate/power of intel is better than amd, but on the other algos hashrate is comparable per core/frequency. In this case, it's way off. |
