I am proud of my latest creation (worked on it for many months).
I have published the zcash, zclassic, ... solver at
   github.com/funakoshi2718/funakoshi-miner
just a few hours ago.

Why yours compared to any others around here?

Hi,

trying with 1070ti on Zcash (flypool), but only getting:


Some machine is working flawless with DTMS, EWBF etc.
Running on Ubuntu...

Any ideas?

Cheers,
Andy



Btw. How to exit from the miner? (currently need to kill -9 ...)

Anybody knows how to install this miner on eth os ?

The command-line argument   -cd 0    requests to mine using first nvidia card.
See the usage example in the github.

To mine using 2 cards you should pass the arg -cd 0 1

If you don't pass -cd (cuda device) arg, you will get 0 sols.

Soon I will add api support.

funakoshiMiner is virus-free. No trojan. This is very important.
It uses SSL (secured).
It is fast.

needs more work 4 1080ti's getting 2580 h/s. ebwf gets about 3000 at same settings. This miner also uses quite a bit of cpu resources.

Let the pool decide which solver is faster.
Check what the pool says after a few hours of running.
funakoshi should be faster.

Also ignore the first report of counters.
It is lower due to handshake with the pool.

Have been running it with the following command:


That still produces 0 Sol...

Anything else I can do?

Cheers,
Andy

Hi Andy

I have tested flypool from Ubuntu.

However I used:
     ./funakoshiMiner -cd 0 -l eu1-zcash.flypool.org:3443 -u xxxxxxxx.rig0

Please use ssl port 3443

In the log you can see that connecting to wrong port 3334 has failed.

No need to sudo.

Thanks Andy

Tested on lowend machine - E2180 4gb ram, 2*1070Ti, Win7, driver 390
makes ~ 700 h/s, vs 960h/s from dstm 0.5.8
Could be due to higher cpu usage, 40-50% vs 20-35% of dstm

The sol/s change all the time.

Each 15 secs different counters are logged.
Some of them higher and some lower.

This is due to the statistical nature of the equihash algo.

How did you choose 700 sol/s. Is it the lowest/highest/avarage?

Funakoshi miner reports each 15 secs the exact avarage in these 15 secs.
The sol/s normaly change each 15 secs (in range of tens per sec per device).

Miners should check what the pool says after a few hours of mining.
Let the pool decide which miner is faster. Miners get their fee from the pool.

Hi,

I'm such a fool - a little typo in the port number and I'm blame your miner not working.
Please apologize, that was totally my fault.
Miner is running and reporting around 380-412 Sol/s, while DSTM was reporting like 490-495 Sol/s.
Let's wait and see in a few hours what Flypool is reporting ;-)

Thanks a lot!

Cheers,
Andy

Hi,

some early reports from my testing concerning mining speed:
(linux, 1 x 1070ti):

Funakoshi:
Miner: 350-410 Sol/s
Flypool: 437 H/s (6+ hours)
0 stale shares, 0 invalid shares
CPU use: 90%

DSTM 0.5.7:
Miner: 490-495 Sol/s
Flypool: 485 H/s
0 stale shares, 0 invalid shares
CPU use: 6,5%

Good thing: Funakoshi is running rock solid (as DSTM is)
So, even at the pool side I don't see any benefit from use Funakoshi.
While I appreciate other miners and competition, I looks (at least from
these early results), that it still needs some work ;-)
Anyhow, first results are promising, and you may find some ways of
squeezing some more Sol/s out of your miner!
Maybe you want to consider a 0% dev fee until you reach a performance
level that is more closer to the competitors?

Cheers,
Andy

Thank you.

Thanks Andy

You are very kind.

I will improve the performance of my solver.

Funakoshi (if this is your name?),

If you find ways to improve it - please go for it!
I really think competition between different miners is a good thing. Furthermore I believe that dev fee is something totally acceptable - if the dev fee is worth the performance and stability. The market is big enough and great and reliable miners will always find plenty of rigs to mine on.
Finally I wouldn't focus too much on Windows. No serious miner (with more than really small number of rigs) will use Windows, because its hell to maintain and never stable as a Linux system...

Cheers,
Andy

added support to Nibirupool (ssl ports) and .bat examples for easy miners setup.

I have improved the performance of Funakosh-Miner  :D

Now the solver doesn't use much CPU.

As a side-effect there is a jump in solves-rate  :)
both on Windows and on Linux.

You are welcome to download the new release and try it.

can you explain, why virustotal find a virus?

https://www.virustotal.com/de/file/4191b32025330aacb7f5bc58c740adbc7012251ce7f5db113d3997eaa3ba4c0d/analysis/1519038341/

A lot of miners get marked due to their excessive consumption of system resources and people using them illegally by putting it on other peoples computers without permission.

...and this has what to do with Funakosh Miner?

Cheers,
Andy

There is absolutely no virus.

Mcafee, Avg, Norton, Kaspersky, E-set, F-prot, F-secure, and all other well known anti-viruses don't see a virus.


I don't know what is CrowdStrike Falcon (ML) that says malicious_confidence_70% (D)

I am not saying that dstm has a virus, but:

    https://www.virustotal.com/#/file/39209c0077e1fc42a5f511ac9e81817073a8d4623ebfc57fbec3308f96457316/detection

You should consult Mcafee, Kaspersky, ... (well known and respectable anti-virus providers)
and not unknown anti-virus providers.

That seriously get lost on you?

sorry this is my fault. I will try the miner.

my ini
funakoshiMiner -cd 0 1 2 -l zcl.suprnova.cc:4142 -u xxxxxxxxxxxx.Rig
I tried to start it almost 20 times,always " not suppoted pool...etc" till at last ....
at a pool side my hashrate is less for about 20% and it  takes 25% CPU more than DSTM or Bminer
handshake with the pool took almost 5min.
I tested it on win10 and 3pc  1070GTX.
is it supported -logfile command ? if is not could be implemented ....

results for 3 hours, and will let it go 24h

I have just connected to zcl.suprnova.cc:4142
It took 1 sec to connect.

Is it possible that your pc has communications problems with the internet?

now started at first and  took 4 mins till line " Authorised worker..."  internet is fine, another rig works normally, and teamviewer is connected
slowly reads GPU-s and temperatures , as i said will let it go for 24h and then will post results, that should be representative
is there anyway to make logs ?

I will add write to logfile and api in the near future.

When I connect to zcl.surpnova.cc the handshake is immediate and authorize line
is also immediate. I have no idea why it takes so long on your pc.

Connection between Funakoshi-miner and Suprnova has been tested from a few
different computers (some windows, some ubuntu). It works fine.
Handshake with the pool is immediate and smooth.

If handshake and authorize are slow on your pc, then I belive that everything else will also be slow.

Full support for more nVidia miner development!

[2018-Feb-20 12:31:43] CUDA error 'CUDA driver version is insufficient for CUDA runtime version' at line 61

Version of CUDA?

Version 9

What hash rate should I expect from titan x pascal (2016 version).  I have not found any miner better than excavator with same settings.  I get around 760 h/s.

I'm executing the exe via a batch file and I had the port in there.  However I copied my EWBF config and it was using port 3333.

funakoshiMiner -cd 0 1 2 -l us1-zcash.flypool.org:3333 -u 123.rig

I changed the port to 3443 in the bat file and I have now connected.  My current hash rate on this rig on flypool is 1.6 kH/ w/ EWBF's miner.  I will update tomorrow with what this value has changed to running your software.

Back from a system failure less than 5 minutes after running the program.  PC became unresponsive, mouse cursor stopped working and then the screen went black.  Music still playing but had to reboot.  System has been solid on the other miners with my current OC's.  I also run xmr-stak on my CPU along w/ the 3 1080s that are in this box.

I am loading the box in the same manner and trying again.

Miner has crashed to desktop with no errors, window just shut down..  Reverting back to EWBF until further development has occurred.  I see potential.  Appeared to be 30 to 40 hash slower than EWBF from mining app reporting.

Hi,

I can see a substantial drop in CPU consumption (around 25% CPU load, was 80-85%) and some speed bump.
My 1070ti test card shows 560-570 Sol/s (which is much more than DSTM's 495 Sol/s...), but let's wait what pool will report.
As previous version: rock stable on Ubuntu 16.04!

Keep going, Funakoshi!

Cheers,
Andy

Thanks for the encoragement Andy

You are most welcome!

Okay, now I see:


What could be the reason?

Cheers,
Andy

This is a bug.
I am fixing it now.
I estimate that it will take me 1 or 2 hours.
I will load the fix and tell you when it is ready.

Fantastic - I really appreciate your hard efforts!

Cheers,
Andy

I have uploaded a bug-fix to current release v0.8

Please re-download funakoshiMiner and funakoshiMiner.exe

I thank Andy for reporting the bug.

My pleasure!

Download and running.

Now showing 510-518 Sol/s on 1070 Ti...every release new hash rate ;-)
Let's see what pool is reporting, will report.

Thanks for the ultra-fast fix!

Cheers,
Andy

I have done my testing under Windows.  Am prepping to convert all my boxes to Linux so will hopefully play with this on Ubuntu later today.  I will also try this on a box that purely mines instead of my personal box that mines and gets regular usage.

Thanks for trying my miner

miner crashed 3 times in 24h, window just shut down. worked about 5-6 hours and ....
has a potential, but there is some bug, add log file

Have you re-downloaded the miner after I have uploaded the bug fix an hour ago?

I will add logfile soon.

Please add luckpool.org

Tested GTX 1060 3GB

dstm - 290 sols
funakoshi - 254 sols

anyway keep up with the good job.

Please, test how many shares on hour?

Funakoshi,

Another crash/bug showing up after a few hours running:


Any ideas on this issue?

Cheers,
Andy

Nice work.

Please add support for some of this pools:

https://zen.zhash.pro/
https://pool.bitcoinzguiding.ovh/

And add how to instruction for newbies.

Hi,

what informations are you exactly missing from his GitHub Page
https://github.com/funakoshi2718/funakoshi-miner (https://github.com/funakoshi2718/funakoshi-miner)?

zen.zhash.pro should something like:


(where -cd 0 1 2 3 represents the GPUs you want to use, starting with 0).

Cheers,
Andy

Only listed pools are supported.
I will have to check connecting with each unlisted pool (basicly its SSL certificate),
and if its certificate is usable I will add it to the list of supported pools.

Are there other heavy graphic applications running on GPU in addition to the miner?

New version works much better and faster, runs stable for more than 12h, no of shares  is little less than Bminer and DSTM, Good work.

Nope, its a dedicated mining (test) rig.

Cheers,
Andy

P.S. After restarting miner now runs for the past 5 hours...will report if it crashes again

Thanks!

Small update on my testing:

on pool side I'm not getting more than 420 Sol/s for 1070 Ti. Funakoshi reports 510-520 Sol/s.
DSTM reports 495 Sol/s and 480-485 Sol/s on pool.

Cheers,
Andy

Before the performance improvement the pool said 437
and after the improvement the pool says 420  :'(
It seams that I will have to do some research.
Thanks Andy

Please support  :)
https://luckpool.org/

I will do it. However it may take a few days (maybe less).
Please be patient.

Andy, I did another comparison of Funakoshi vs Dstm-0.6
on a Ubuntu 16 cloud server with gtx 1070 GPU.

First I run Dstm for 2 hours and after that Funakoshi for 2 hours.
2 hours is too short time (but I wanted to test both solvers in
as close as possible period of time).

Dstm:
cpu: 6%
I/s: 237
Sol/s avg: 442 (reported by miner)
Flypool avg sol/s: 399


Funakoshi:
cpu: 16%
I/s: 240
Sol/s avg: 446 (reported by miner)
Flypool avg sol/s: 401

In the following graph from flypool,
Dstm 2 hours recording is on the left-side
and Funakoshi 2 hours recording is on the right:

    https://imgur.com/JQNKKo3

In this configuration both solvers seams to have similar
performance. I also noticed that there are many large
jumps in flypool graph in both directions.

Maybe different configurations gives completely different results.
Maybe different hours of day in flypool gives different results.

However I will continue to try to find ways to improve the performance.
Thanks for sharing your experience with me.

I have added support of LuckPool and updated the current release v0.8

thanks for the miner, but its crashing when I want to use this pool:
europe.ethash-hub.miningpoolhub.com:20575

can you help out?

To mine zclassic you should use the domain
equihash-hub.miningpoolhub.com instead of
ethash-hub.miningpoolhub.com

See the examples in https://zclassic.miningpoolhub.com/
Disregard the server names and read the examples.

Read examples of command-line arguments to Funakoshi-Miner:
     https://github.com/funakoshi2718/funakoshi-miner

that was my mistake, I just took the green server names… instead of reading further.

MPM should fix this ;) thnx for the quick answer

Funakoshi,

Okay, let me try to run (unfortunately not in parallel) two more 24 hour test.
One with your miner, and one with DSTM, both on flypool with Zcash.
Will report back.

Cheers,
Andy

Any plan for new update?

Funakoshi Miner supports miningpoolhub.com.
Miners should use domain equihash-hub.miningpoolhub.com
For mining equihash coins like zcash.

What is the speed in comparison to EWBF?

You are welcome to check for yourself.
Don't belive me and don't belive others.
Many of the posted benchmarks are not objective.

If you ask for my non objective opinion:
I think that it depends on the specific computer & gpu model.
On windows-7 & gtx 1080 I have measured that Funakoshi
has more sol/s (but not much more).

I am currently working on some performance improvements.
I will upload them soon.

Hi,

so, I ran a 24h test on flypool with one GTX 1070 ti on Ubuntu 16.04 with OC (GPU +200, MEM +700).
The miner (Funakoshi) shows between 505-519 Sol/s in the console. Flypool reports different:

Flypool (https://ibb.co/eKyKQx)

In reality pool reports average of around 415 (+/-5) Sol/s. For comparison DSTM reports an average
of 485 (+/- 5) Sol/s with the same settings. Roughly +20% speed for DSTM...

Funakoshi needs another speed bump to be on par with the current Equihash miners.

What I really do like very much with Funakoshi miner is its "SSL only" approach. That is really a big
plus.

From my point of view, Funakoshi miner is missing:

• better speed
• telemetry/api
• increased stability

I'm sure, Funakoshi is already hard at work, addressing above list ;-)

We are all looking forward with what Funakoshi is coming up!

Cheers,
Andy

Tomorrow I am planning to release version 0.9 of Funakoshi-Miner.

This release will include the following benefits:

  1. Reduced CPU usage (both on Linux and on Windows).

  2. Support for log-file (a new  -f  command-line argument).

A few days afterwards I will also add API support.

 :)

Added log-file as promised.

Checkout release v0.9 for using log-file
   -f fileName   (in command-line args).

Also fixed some bugs, and reduce %cpu.

It will take me a few more days to add api.

In a few days from now I am going
to publish release v1.0 of Funakoshi-Miner.

It will include a performance boost  :)

What's the fee?

1.5

Version 1.0 of the miner has been released.
Made some gpu-side performance improvments  :D

    https://github.com/funakoshi2718/funakoshi-miner

Hopefully we'll get some test results soon from the update

At my 3 x GTX 1080 less 12% Hash and 7% more power consumption at lower TDU.

Please check on the pool side and see.

The sol/s in the EquiHash algorithm change all the time in
the range of 30% to each direction. I am still experimenting
in calculating more or less stable avarage.

What is important to you is what your pool says.
The pool estimates an avarage based on submits.
From hundreds of sol/s each second, there is 1 submit
each 1 to 60 seconds (depending on the difficulty target
of the pool). Thus the pool estimate is also unstable.

You should run the miner a full day to decide what the
pool says.

Time to get our hands dirty again ;-)

Fantastic job, Funakoshi!

Cheers,
Andy

Finally decided to give this a try:

[2018-Mar-01 15:25:56] [GPU-3] CUDA: failed to alloc memory

6x 1060 3GB. I have a 16GB pagefile.

Dialed back overclock to stock, same results.


funakoshiMiner.exe -l us-east.equihash-hub.miningpoolhub.com:17023 -u XXXXXXXXXXX -p x -f log.txt -cd 0 1 2 3 4 5

I didn't test the miner on 1060 3GB.
It seams that the miner requires more memory than available on the gpu
card. To support 1060 3GB some changes need to be done in the code.

All other equihash software support it, its no biggy if you dont put it in.

Hi guys, I am new here.

I have exactly the same problem: CUDA: failed to alloc memory
Running a 6 GTX 1070 Ti rig on Windows 10.

Any ideas on how to solve it?

What is the command you used for running the miner?

that is the command I used.

Just for testing. Can you try to use only 3 devices -cd 0 1 2
and see if the problem continues.

this is the one I used:

funakoshiMiner.exe -cd 0 1 2 3 4 -l eu1-zcash.flypool.org:3443 -u address.minername

I took it as it was from the web and just changed my wallet address and miner name.

Hello Funakoshi,

Are you maybe interested in this project? I am willing to offer you 30% of all earnings mined. This could be a very profitable project where we can earn upto 4-7k USD a day. Please let me know if you are interested.

https://i.gyazo.com/3d76d1ec0710dc4ee8adf8a63608a94d.png

@Funakoshi

I just noticed that on Github, the is a spelling mistake on the title of the miner!
"Funakoshi Eqhihash Cuda miner"

Unless it is on purpose?!
If it's the case, I'm curious what's the meaning! ;D

Thanks for this new miner!   I'm installing it right now; it seems very promising  :)

Thanks a lot. It was a typo mistake. I fixed it.

Why SSL only? Are you hiding the network traffic of your miner?

You can easily verify that Funakoshi-Miner only connects to the
miner chosen pool and to no other server.

Exactly 1.5% of submits to the pool are used as developer fee.
This is explicitly explained in the github page.

SSL is used to protect against "man in the middle" changes of
messages to/from the pool.

All submits to the pool and messages from the pool are logged
to console and optionaly to log file.

Could you please look if you could add Equihash 96/5 algorithm?
There are enough Equihash 200/9 miners already, but a good 96/5 is still in high demand.

Your suggestion above is meaningless, thank you.

"mime-location" does not mean "mime-us" but "us", please check it. Read the examples.

Thank you for prompt reply. Did you check what I posted above ? It says (on getting started) 'US miners: mine-us.miningspeed.com or EU miners: mine-eu.miningspeed.com'. I can connect mine-xx.miningspeed.com on regular stratum no problem.
It's just this coin (CMM) using this stratum format unlike most of other coin using location.miningspeed.com.
Please you check yourself.

The certificates used by miningspeed are invalid (not trusted by most browsers).
I added the certificate of us.miningspeed.com as privatly trusted to the miner code.
However the domain mine-us.miningspeed.com doesn't use the same certificate
as us.miningspeed.com and the used certificate is also problematic. I can add this
certificate as authorized in the next release of the miner.

I have boosted the performance of Funakoshi miner.
Now it is the fastest cuda miner.  :D

Have you fixed the 'invalid certificate' issue ?
Look, I want to try your miner, but it still has the same 'invalid certificate' as the previous version.

Sorry, but not yet. My top priority was to imrpove speed.
Now that Funakoshi Miner is the fastest miner I will give
priority to functionality. Your request will be implemented
in next release.

Gonna try tomorrow. If it's faster than dstm, with less fee, I'm in

Thnx m8 nice to se competition

You do know that this thing dont work out of the box ?
Why not make a pakkage complete so that this is click and play ?
Now i get all kind of dll missing errors  ??? even a nvml dll  ???

You can download all needed dlls including nvml from Funakoshi-Miner github release page.

Yeah like a jigsaw puzzle  ;D ;D
Found it pffff
now i get another error only support sm 6.0 and higher ???

Driver version latest 391.35
Memory Clock 650
Core Clock default 0
Is this hashing normal?
Can someone tell me about it? ???

hi,well i'm getting a bit higher I/s (around 405 on 'stock' 1080ti gigabyte factory watercooled,dstm around 399),but comparing to dstm,there is significantly more bus traffic(bus interface load around 43%,dstm around 1%),i'm single-card miner,so for me it is not an issue,but i'm not sure if this might be problem on slower cpus/more cards,also whole pc draws a little more (dstm around 280-290w,funakoshi around 290-300w,as precise as corsair link power supply can report it)

also coil whine is different,quieter(that i kinda like,because of less stress on caps i guess:) )

if i may a little suggestion,console colours? :)

anyways,i'm gonna play with it for a while,thanks

k.

Can I use GTX 1060 3GB with the latest funakoshi miner?

Sorry but no.
Funakoshi Miner requires at least 4 GB.
