Hi all!

This is improved version of open source miner for zcoin.
Tested and developed under ubuntu 16 , cuda 10, 415.25 driver. Tested on mintpond pool.
Improved speed and moved Merkle tree generation to GPU.

WARNING! READ BEFORE USE!

1. Cards will eat every watt of tdp and they will be hot. Check your PSU
2. This miner have problems with extranonce2 and will run out of nonces on high speed rigs. It will abort() itself if running out of nonces, so launch in loop or launch 1-2 cards per instance
3. This miner will force exit too, if pool is lagging (annoying stratum_gen_work: job not yet retrieved message)
4. Please, ignore this error GPU #2: result for 27713c34 does not validate on CPU! - It means nothing, full result checks not running on GPU, If this message is rare, it is OK.
5. To reduce CPU work and number of messages "result for 27713c34 does not validate on CPU" please use static diff 2^n aka 1024,2048,4096.. on mintpond: -p pass,d=4096,strict
6. In some rare times pool do not send diff, miner will use default(8192), you can change it in util.cpp file



OVERCLOCK

+mem, +cpu, all is working, for 1080, 1080ti Pill is working too.

SYSTEM requirements:

CPU - any, Celeron is OK
RAM - 256M per card
GPU - 5G of vram
For 20x0 cards: edit Makefile.am and change compute to 75

DEVFEE

Devfee is ZERO.
If you want to donate, send coins to my addresses, that shows after miner launch.

Ubuntu 16.04 with Cuda 9.2
https://github.com/dhan000/ccminer-mtp/releases/tag/9.2

MTP algo becomes one of more profitable for GPUs and there is a need for such miners. It is suitable to have a Windows version for the majority of the miners.

Windows versions compiled by djm34 are here https://github.com/zcoinofficial/ccminer/releases

You have downloaded on Github ccminer release 1.1.6 again instead of the new version 1.1.7 (https://github.com/zcoinofficial/ccminer/releases). At least in miner window it is shown 1.1.6. Nevertheless its performance is much better than previous 1.1.5 release (small test of your miner on P106-100, GTX1080 and 1070Ti is in Russian article here: https://www.cryptoprofi.info/?p=1475)

the link for 1.1.7 in Github download a file displaying 1.1.6...

There are different releases of miners because they have different sizes. I think that developper didn't change the number of release in compiled version 1.1.7.

Works great with Pascal version.

I downloaded the windows of this miner from zcoin's github, compiled by djm. Could only run 2 cards max, otherwise it error -22 and closes. Does the windows version need more than 256mb ram per card? Or is it just low virtual memory?

My specs:

Pentium G4560
7x 1080ti
4gb ddr4
30gb virtual mem

krnlx/djm version needs more virtual memory than cryptodredge

This ^^

I set virtual mem on my 5x 1080 rig at 64GB to be safe. Also running multiple instances requires even higher swap file size apparently. Just keep increasing until the error disappears.

performance wise its on par with CD 0.15.1 , but biggest plus - krnlx work is rock stable , not a single issue or crash.

p.s. power limit is your friend with this one :P

thanks for the new version 1.1.10

Can we get hashrate info on 1080ti cards? OC settings? Eth pill works?

I get around 3400 kH/s  (w10, core i7, single 1080i, latest drivers)
cminer_61 v1.1.10 (krnlx), -i 22, d=1024, mem +0, core +110, power 80%

mem & pill doesn't seem to do much, core has huge impact but miner has more issues with MTP algo when going high...
Cryptodredge is doing a bit more hashrate, but slightly more reject and instable with 1080ti (it's ok for me on 1070)
fix diff of d=1024 is important to reduce rejects...

I get more hashrate running both miners (krnlx & Cryptodredge 1700 + 2600...) in //,  but it will run for 5 to 20 hours only

thanks for the development  :)

Thank you my man!

version updates are good for mining. with an increasingly good version, this will make the system of mine that there will be more. In addition, the combination of MTP will provide systems to the GPU in order to provide faster results.

2X 1080TI + 6X 1080 + 1X 1070 74GB SSD Virtual memory + 8GB DDR4 Memory crash! Fixed pls

I'm using your program for Zcoin. It has less hashrate than CryptoDredge on default settings, but if you increase intensity it's OK. Sometimes there is a problem "an illegal memory access was encountered". Maybe you can advise something to avoid it?

Does not work on Nicehash.
Does not send share, constantly gives errors:
accepted: 0/15 (diff 0.000), 9747.16 kH/s booooo

Will there be support Nicehash?

Thank.

Use cryptodredge to mine MTP it is much better than this because you will receive more error while using it compared to cryptodredge and it is much faster than this.

The only problem is the dev fee is 2% in cryptodredge compared to this miner no dev fee.

Alternatively you could use TT miner which is both faster than krnlx's miner and has lower fee than CryptoDredge for similar speeds... And very stable to boot.

Thanks for the suggestion it seems that there is a little difference on the hashrate cryptodrege gives me more hashrate than ttminer but just a little hashrate.

Let me ask if how much the dev fee of this miner?

TT miner Does not work on Nicehash.
Does not send share (MTP-100 or MTP-92), constantly gives errors:
16:18:36 Error(pool): Invalid xnonce2 size; is miner not compatible with NiceHash?(65537)
16:18:36 GPU[0]: ***Rejected 242 ms. mtp.eu.nicehash.com:3374 [172.xx.xx.xx]

I think the dev (TrailingStop) is working on it. But you might as well pop into his dedicated TT-miner thread, no need to pollute this one anymore. Just wanted to point it out earlier, that's all!

Interesting ...

Will be testing this version when time permits this week.
