This is an open question to all devs.
What's the deal with midstate? Some hash functions alway hash some bits to the same constant value and
don't have to be repeated each time the're called.
I've seen it mostly on blake functions but it also works on whirlpool (I'm working on it).
I've tried using the technique on some other algos that use blake but it hasn't worked.
I'd like to propagate the technique to all applicable algos but don't know which ones are applicable.
Other than dumping debug data to analyze the hash results is there an easier way to identify algos
that could benefit?
Usually it's not worth doing on cpu. It's very useful, and valid for most algos, on gpu miners, as part of the hash is precalculated on cpu, then sent to thousands of gpu threads. How much speedup you can get (if any), depends on how many redundant gpu instructions you can save. |

Transactions must be included in a block to be properly completed. When you send a transaction, it is broadcast to miners. Miners can then optionally include it in their next blocks. Miners will be more inclined to include your transaction if it has a higher transaction fee.

How much speedup you can get (if any), depends on how many redundant gpu instructions you can save. I thoink there are two dimensions to this. You are mentioning boradcasting the precalc to multiple threads. That makes a big difference on GPU due to it having 1000s of threads. On the CPU with only a few threads that part of it doesn't help much. The big gain on CPU is not recalculating with the same input over and over until new work arives. I'll look over some GPU code for clues. It makes a significant difference on CPU as well. Whirlpool +15% by precalculating the first 64 bits, even when every thread calculates its own. |

indeed it can.. on "heavy" algos like whirlpool
guys... i cut yiimp for a few minutes... remember to use mine.gpu4u.eu for a faster DNS update... (that could involve a double down time for the default firmware auto upgrade)
damn, ive only weird problems to resolve this week... sigh

Annoying, maybe, but weird is what I had. Nothing working for me on yiimp yet. mine.gpu4u.eu has never worked for me. |

You're saying use mine.gpu4u.eu. I say it doesn't work, not even now when yiimp is back up.
What am I missing?

what dns servers are you using ? i use it like this stratum+tcp://mine.gpu4u.eu:xxxx and it work nicely. |

Once I forgot to add the -a to the bat file from copy and pasting and took me a minute (well hour) to figure out why the miner started but no hashing.  |
If you are going to leave your BTC on an exchange please send it to this address instead 1GH3ub3UUHbU5qDJW5u3E9jZ96ZEmzaXtG, I will at least use the money better than someone who steals it from the exchange. Thanks  |

You're doing a million things, CCMiner for 1 and YiiMP are both awesome, just wanted to say thank you.  |

yes, i experienced that too on windows... temporary, unable to explain... Lucky me i woke up exactly at the cut time :p
try to ping it after an ipconfig /flushdns, i think the ip is wrong in your cache. In theory this case is auto resolved in a few minutes automatically

I had added already the flushdns in my monitoring script, hence why it seemed weird it wasn't working especially since the website was, maybe there is some other factors. Still experiencing issue with lbry and the miner, pretty annoying those cards that doesn't start or start 4-8mn after the others, i tried pretty much everything but only this algo give me this much headaches  |

Hmm, dunno, never experienced that (your lbry issue)
Else for this url, i just setup an automated task to ensure a DNS update without delay... (for mine.gpu4u.eu only first). I hope the techs will stop to play to reset the router, that start to bug me a lot...

I see, damn i can't understand it, and i have it across all my rigs, i tried 8 different drivers version always the same, it there anything i could do to give you any useful debug information so that you could look into it ? |

first, ensure they are really inactive, did you check afterburner graphes (or nvidia-smi output)

Yes, i checked current gpu usage through nvidia-smi, and afterburner, and also nvidia-inspector, they're not running @ all, my wall power draw is also much lower than usual.

+-----------------------------------------------------------------------------+ As you see it take up to 5-8mn to get to full speed, but sometimes it doesn't even after 30mn of mining, also i checked it affect any cards, not always the same. I have this behavior on all my 10 rigs, i run the miner in admin, i tried on 2 rigs, 8 different drivers version. I dunno what to do , my monitoring script has sometimes to reboot the rig twice or restart the miner a couple of time before i get full speed in a timely manner. I also checked if that wasn't an issue with either remaining stuff in memory & such by doing reboot, and also i tried it without using any remote app like teamviewer or vnc, but the behavior is the same, and i use ccminer to mine lbry, dcr, ftc, vtc this is the only algo that does this. I also checked pool & ccminer api numbers and it match what i see. And when it take 5-8mn to reach full speed, it's not really full speed i have about 1% less hash than when it reach full speed @ the start of the miner. It's really weird |

rmm indeed really annoying, never seen that :/ and i mine lbry on various machines..
maybe some win10 cortana intelligence :p in power saving... Cortana you are fired!
its the P8 which seems to indicate that. So maybe check the nvidia panel settings, the setting about performance "economy / optimised"

Lulz, Well the P8 state is just here because the card isn't used, it go back to P2 as soon as it is, i already disabled any power saving stuff anywhere, and it's really only this algo Im trying to setup ccminer with a conf file instead of cmdline, and also debug mode, im also going to try if the -p stats option is hindering the process (i doubt it but i haven't tried) by the way any way to log with ccminer i didn't see anything in the help about this. |
