cryptonight-heavy?

[L1LjSHX]

POW war is started. Thanks Bitmain and baikal...

@xmrig for Graft about update: https://www.graft.network/2018/03/27/upcoming-graft-software-release-major-network-update/

[xmrig]

@2010phenix thank you, I will update info later, according their github, will be used Monero v7 PoW graft-project/GraftNetwork#100
@esfomeado It just a new difficulty algorithm, not a new PoW, this change not directly affect miners.

[sergneo]

@xmrig
Sumokoin
‏ @sumokoin

Due to recent network's hashrate high fluctuations (our best guess is ASICs trying to get their last blocks) stalling the network, we decided to bring the fork's blockheight closer at block 116520. Binaries will be released shortly.
Thank you

[Zambi9]

What happens if I just continue using version 2.4.4?

[xmrig]

You shares will be rejected by pool, you can continue use older versions only for coins which not change PoW yet.

[DuyQuang06]

@xmrig IPBC coin update new Cryptonight "Variant"

https://ipbc.io/eng/announcements/ipbc-fork-available-in-testnet/

: D

[DrStein99]

Scratchpad to 4k !?!? oh no!

[telebog]

I have a Ryzen 1700 Cpu. Tried on Sumokoin and works only on 4 threads ~230 H/s If I configure Json to use 8 Threads it works only with ~130 H/s. Any idea what settings to use to work normally ~500H/s?

[xmrig]

@DuyQuang06 Thank you for link.
@DrStein99 Now I'm confused how name this thing, maybe cryptonight-ipbc or cryptonight-v7-jumbo-crazy, because just variant not enough... 4 MB scratchpad.
@ipbc-dev Reward most crazy PoW change now moved from Sumokoin to you.

[xmrig]

@telebog No it not possible, it new heavy algorithm.

For reference i7-4770 original hashrate 300 H/s (4 threads) new is 136 H/s (2 threads). New algorithm specially designed to hurt CPUs hashrate. CPU vs GPU balance changed to prefer GPU mining. Scratchpad size is not main reason for such low hashrate, main loop length reduced twice, main reason is thing named half-step with additional memory access in main loop. If simple remove this half-step for test, hashrate is 237 H/s, but of course it make invalid hashes.

[Sayyiditow]

haven protocol did not work for me, i keep getting rejected share, even with @cryptonight-heavy change on config.json. @xmrig

[ipbc-dev]

@xmrig

Call it cryptonight ultraheavy ?

We have forked your repo and implemented the new algo, CPU, AMD and Nvidia are working, we are testing and optimizing it, when we are done we can do a pull request.

https://github.com/ipbc-dev/ipbc-miner

[xmrig]

@Sayyiditow You should use only version v2.6.0-beta1 for it, I was checked mine Haven, it works.
@ipbc-dev I think cryptonight-ipbc is good, pull request would be nice, please use dev branch for it.
Thank you.

[rhlug]

Manual action required, algo option should changed to cryptonight-heavy and threads count should reduced twice.

Can intensity be halved and keep same # of threads?

OLD

    "threads": [
        { "index": 0,  "intensity": 1920, "worksize": 8, "affine_to_cpu": false },
        { "index": 0,  "intensity": 1600, "worksize": 8, "affine_to_cpu": false },
    ],

NEW

    "threads": [
        { "index": 0,  "intensity": 960, "worksize": 8, "affine_to_cpu": false },
        { "index": 0,  "intensity": 800, "worksize": 8, "affine_to_cpu": false },
    ],

OR is this required?

    "threads": [
        { "index": 0,  "intensity": 1920, "worksize": 8, "affine_to_cpu": false },
    ],

Or does it matter?

[xmrig]

@rhlug it related only to CPU miners and it was written when only CPU version was available, so if you was run 2 threads you should run 2 too, but about intensity no need reduce it twice, optimal values should be above 1000 but lesser previous intensity, only experimenting may suggest you now.
Thank you.

[Sajo8]

TurtleCoin has successfully forked on April 8, at block height 350000, please update

[pejuangbitco]

how changed algo to cryptonight-heavy? i use cpu

[xmrig]

@Sajo811 Thank you I updated info.
@pejuangbitco change this line in your config to "algo": "cryptonight-heavy", and use miner v2.6.0-beta1

[Sayyiditow]

@ipbc-dev any idea when you will fork?

[2010phenix]

@xmrig Graft add pool for test... and strange, only NVIDIA and AMD miner, link: https://bitcointalk.org/index.php?topic=2115188.msg34305644#msg34305644
-- cut --
The team completed an update to the public testnet.
A new pool for mining functionality test is available here : http://pooltest.graft.network

[2010phenix]

@xmrig Graft move update date:
-- cut --
PATCH 1.1.1 HAS BEEN RELEASED – MAJOR NETWORK UPDATE ON BLOCK 65110
We decided to make the major network update sooner in order to minimize the possibility of hashrate attacks. Patch version 1.1.1 is now released and available for download from master. The major network update itself is rescheduled for block height 65110, around April 14th.

[felipe-vvoosh]

ETN is doing what? Such a slow team...

[ipbc-dev]

@xmrig yesterday with new Baikal N on new v7 light.

[xmrig]

@ipbc-dev Aeon still not fork to v7.

[ipbc-dev]

@xmrig ups sorry my bad, i supposed is already done, just taked a look here https://www.cryptunit.com

[sibero]

intensecoin fork to v7 PoW - May 14, 2018 https://intensecoin.com/2018/04/15/april-15th-update/

[felipe-vvoosh]

ETN is just playing with the devil now, the network is at 650 MH/s and the fan boys are saying that ASIC miners are fine as the team keeps struggling to fork and become ASIC resistant. It’s a blind trusting.

[marki555]

@sibero That is not accurate. 2 days ago ITNS released new plan for emergency fork in the following few days - https://intensecoin.com/2018/04/16/imminent-hard-fork-and-network-attack/

[2010phenix]

@marki555 yes for now April 21

[cmorsucci]

aeon v7 is supported?

[xmrig]

Masari will fork too, information updated.

[2010phenix]

almost all coin use or monero v7 clean, or option variant should set to 1
maybe OLD monero change to variant 1 and all other new-NEW-nEW altcoin simple work with autodetect or we can't detect?

[xmrig]

variant should set to 1, autodetection is useless since all other coins use block version below 7, except GRAFT, but actually good idea change default to 1 sometime later. I think you already saw xmrig/xmrig-proxy#168 it allow pool explicitly inform miner about what exactly algorithm needed.

Now cryptonight-lite has 3 possible variants and cryptonight will have 3 variants soon, total 7 algorithms now.

[MoneroOcean]

Does xmrig already reacts to algo change provided by pool/proxy?

[bobbieltd]

@MoneroOcean Under my tests with xmrig 2.6.0 beta 3 / xmrig 2.5.3, xmrig doesn’t change algo.

[2010phenix]

@xmrig Yes for proxy very good and simple idea send variant and algo data and even more, no other solution....
but look on miner, we have already programmable algo-Terminator )) , demand more and more time for you(with not clarify itself algo Devs) and for ppl who used xmrig..
autodetect all this things(most like new algo fork from monero) solve and save time.

@MoneroOcean us say xmrig detect be in 2.6 stable master (for now only beta)

[randing89]

@xmrig
Hi
BBSCoin has been forked to Cryptonight v7 on height 72500.
Original announcement: https://twitter.com/bbscoin_xyz/status/986098944387072001
Our official pool is: http://pool.bbscoin.xyz/

[2010phenix]

@randing89 Hashrate(Network Hash Rate: 267.77 KH/sec) not to low for IN ?

[mcnih]

is ETN going to fork the algo or not? thanks

[cyberghost66]

ETN BLOCKCHAIN UPDATE MAY 30TH
https://electroneum.com/2018/04/25/blockchain-update/
( https://youtu.be/XJVspl2sJWQ )

[bobbieltd]

@MoneroOcean
if (algorithm.isValid()) {
LOG_ERR("Incompatible algorithm "%s" detected, reconnect", algorithm.name());
}
else {
LOG_ERR("Unknown/unsupported algorithm detected, reconnect");
}

No algorithm switching 😂 only for variant.
@xmrig Do you plan to make algo switch (lite, normal, heavy) in the future ? Scratchpad size issue ?

[Zambi9]

Do I understand correctly, that for Monero we will potentially need to change the miner every 6 months?

[sergneo]

@Zambi9 in the future it is expected that Yes it is necessary

[stoffu]

@xmrig Aeon is forking on June 3rd: https://github.com/aeonix/aeon/releases/tag/v0.12.0.0

[QwertyJack]

@xmrig Etn is gonna fork these days: etn update

[xmrig]

Recent information about algorithms/coins https://xmrig.com/docs/supported-currencies this issue not updated for a while, and not actual anymore.
