Bitcoin Forum

Hi community,

I'm glad to say that mumus (https://bitcointalk.org/index.php?action=profile;u=127442) released his version of jhPrimeminer there: https://github.com/hg5fm/jhPrimeminer

MrMagic (https://bitcointalk.org/index.php?action=profile;u=3986) gave us this link and additional info about mining:


So now you don't need to have separate wallet on each mining machine, and it is big step ahead to getting pools up and running! Many thanks to Mumus!

Edit:

 ;)

A lot of good news and DTC applications will be released this week ;) But this one was a surprise, really.

Unified instruction about building this miner both under Linux\Windows will be released soon.

Any info about pools?? Waiting for them while solomining at 500 primes per sec hihi :)

This miner is one more step to pools. As I promised, when we have any working pool (even in beta mode), I'll announce that immediately.

Thanks!

So what does this allow? Multiple computers to mine a single block via getwork?

Yep, just wallet on one computer and miners on all others.

do you know how to compile it under linux ubuntu?

Current version (in OP) is only for MS VS, but mumus said that he'll try today to add this DTC code to linux port of primeminer.

I don't know how to compile it. Can somebody post a version for windows x64? THX a lot!!!

Here is the version I am using. It is compiled for x64-AVX processors. I have mined 3 blocks so far using this. If anyone wants the source I can create a repo and post it. The only changes I made are the ones I posted above and some stat output formatting changes.

https://dl.dropboxusercontent.com/u/20044454/DatacoinMiner.zip (https://dl.dropboxusercontent.com/u/20044454/DatacoinMiner.zip)

I personally would love to see the source. What is the dll for?

Also can you give information on how to compile?

what is command line for solo mining?

thx! Did I need to write something in the datacoin.conf?

thanks a lot kind sir

Is it just me or is the forum broken?

I will get the source up asap.

The dll is for Multiple Precision Integers and Rationals (mpir). This is a library that is used to give a performance boost for computing the primes (from what I understand of the code).

Instructions for compiling from https://github.com/hg5fm/jhPrimeminer

Needed tools:
 - Visual Studio 2012 Express or above
    - The compiled version I just posted was compiled using Visual Studio 2013 Professional, but I have also compiled it using    VS2012 Express)
    - You may be able to compile it using a lower version of Visual Studio such as 2010.

1) Download the source code to your machine
2) Open up the primecoinMiner.sln
3) Add transaction.h to the "Header files" in the project by right clicking on "Header files" -> Add -> Existing item -> transaction.h (located in the same folder as the project)
4) Add transaction.cpp to "Source files" the same way you did transaction.h
5) Open main.cpp and look at the top of the file for "bool useGetBlockTemplate = true;" change it to "bool useGetBlockTemplate = false;"
6) At the top of the VS window change the drop down that says "Debug" to "Release-AVX"
7) Make sure Platform is set to x64
8) Right click on "jhPrimeminer" project in Visual Studio -> Properties
9) In the right panel of "Solution 'primecoinMiner' Property Pages click "General" under "Configuration Properties". Make sure platform toolset is set to the correct version. (For example, I am using VS 2013, so I use toolset "Visual Studio 2013 (v120)"
10) Under C/C++ -> Optimization I have Optimization: Maximize Speed, Inline function expansion: Any Suitable, Enable intrinsic functions: Yes, Favor Size or Speed: Favor fast code, Omit frame pointers: No, Enable fiber-safe optimizations: No, Whole program optimization: Yes (/GL)
11) Under C/C++ -> Code Generation  Change Enabled Enchanced Instruction Set to AVX or SSE2 depending on your CPU's architecture.
12) Under C/C++ -> General I also enable Multi-processor compiliation to speed up the compile time because I am impatient.

Everything should compile and then you are good to go!

after about 5-7 min crashing wallet when solo mining with this miner.. (( has the same problem somebody?

These are the settings you need in datacoin.conf to be able to connect the miner to your wallet.

server=1
rpcallowip=*(or whatever IP the miners will be connecting from)
rpcport=<port> (whatever port you choose to open for the miners to connect to your wallet)
rpcuser=<username> (whatever username you want)
rpcpassword=<password> (whatever password you want)

Example:
server=1
rpcallowip=*
rpcport=4778
rpcuser=DatacoinMiner
rpcpassword=MinerPassword

Then you can connect the miner to your wallet using "DatacoinMiner.exe -o http://localhost:4778 -u DatacoinMiner -p MinerPassword"


*Edit: I am using rpcport 9199 on my own miners.

Hmm strange. I have been running for about 2 days with about 12 machines connected with no problems. 3 blocks mined so far.

Which version of the wallet are you running? I am running the latest QT wallet from here http://sourceforge.net/projects/datacoin/files/datacoin-qt-131204.zip/download (http://sourceforge.net/projects/datacoin/files/datacoin-qt-131204.zip/download)

So we can make a private pool with someones wallet ?

Yes. I have 12 machines running on my one wallet.

@MrMagic:

Good job!
I was able to sucessfully compile it with VS2013 in AVX & non-AVX versions.

Can someone explain this to me:

Datacoin allows anyone to place entire files permanently in its blockchain - so how long until someone uploads illegal material and then everyone who runs a Datacoin node can be arrested?

I answered this questions a lot of times. Firstly, all coins that support messages and small data can contain such content - Namecoin for example.
Secondly, files stored in blockchain are not just files on your harddrive - they're turned into blobs and encrypted into blockchain. You need special soft (wallet) to get these files, so it cannot be easily proved that you have some illegal content. I can write a program that takes definite bytes from Windows common files and writes them to file '1.jpg'. This program won't contain any such content, but if you run it, you can get illegal picture from windows common files. So do you think that all Windows users can be arrested in such a way? :)

And lets say it:

Illegal content is only illegal from someones point of view.

We all agree that pedobear is bad guy, but we all agree that some documents should be acessible to all, even if some people say they are secret.

We are making free decentralised data service, which cant be closed that easily.

We are making Internet more free.

did anyone have active testnet node? my wallet in testnet cannot sync...

I just want to check my config is right, so I want test it in testnet.

Hi,
I've just updated the source at https://github.com/hg5fm/jhPrimeminer with some fixes related to what MrMagic suggested in his previous post.
Now the miner will accept "-getwork" command line parameter that can be used to do the classic solo mining using datacoin wallet and getwork protocol. It also should have some fix that may prevent the wallet crashing problem reported by some users.
A precompiled binary can be found here: https://mega.co.nz/#!mRMnSAwC!ZoAHgBVIMIOthnRQOq9ukRWWz-hvayNyshB1oXpHcXU (https://mega.co.nz/#!mRMnSAwC!ZoAHgBVIMIOthnRQOq9ukRWWz-hvayNyshB1oXpHcXU)
Compiling the source can be done using Visual Studio 2008/2010/2012/2013 or by installing the Windows SDK.
If someone doesn't want to install Visual Studio here is a little guide to compile it with windows SDK.
1. Download and install the Microsoft Windows SDK for Windows 7 from: http://www.microsoft.com/en-us/download/details.aspx?id=8279 (http://www.microsoft.com/en-us/download/details.aspx?id=8279)
2. Download and extract the jhPrimeminer source code from: https://github.com/hg5fm/jhPrimeminer/archive/master.zip (https://github.com/hg5fm/jhPrimeminer/archive/master.zip)
3. Open the "Windows SDK 7.1 Command Prompt"
4. Change the current directory to the extracted jhPrimeminer source location, for example:
5. Compile the miner with the following command:
The jhPrimeminer.exe will be located under C:\jhPrimeminer-master\src\bin\ directory
In order to run it you will need also the mpir.dll which depends on MS Visual C++ runtime. One can be found in the jhPrimeminer-v8.2.zip mentioned above.
6. Run the miner
Of course replace the username and password with your values specified in the wallet's datacoin.conf

You may want to test that your miner and configuration works well using the datacoin  testnet network where the difficulty is very low so you can find block easily.
In order to do this run the latest wallet (I've compiled form the latest code today, earlier versions may not work on testnet) with the following command:
Then run the miner:


Regarding to building the miner with different compilation flags targeting some CPU features like AVX, SSE3, SSE4, etc., I've found no significant performance improvement in my tests.
More important is the version of the mpir.dll that is used by the miner which can lead to 20-30% improvements with specific CPUs.
A package of some precompiled mpir.dll can be found here:  https://mega.co.nz/#!DMdBCSII!ZYAYTzxeNJu_JzKVpUFNa01ehTYfHQHH_leijY28wbQ (https://mega.co.nz/#!DMdBCSII!ZYAYTzxeNJu_JzKVpUFNa01ehTYfHQHH_leijY28wbQ)

I've also tried to solo mine datacoins with one of the Linux port of the jhPrimeminer that was forked form https://github.com/hg5fm/jhPrimeminer at an earlier stage. It should support getwork protocol but  looks like it is broken now. I'm working on the fix and will post and update when I have something.

Thank you mumus for fast reply!

There is (at least) one wiki*eaks document (a leaked document) stored into the bitcoin blockchain.

Nice! Thanks for the update mumus. I also tested with different arch builds but couldn't see any noticeable difference either. Funny that you mentioned messing with mpir as I was looking at that next for any performance increases. I suppose this is why you chose to link it using dll instead of lib, so that the dll could be replaced easily by end users. Curious though how you built mpir for sandy bridge. I did not see that in the visual studio project provided on the mpir site. The reason I ask is I would like to build a haswell dll if possible.

Thanks again!

*Edit: Just tested sandy bridge mpir.dll on my 4770 (Haswell) and some 3770s (Ivy bridge) and it appears to give about 3x performance (based on 3/4 ch/hr) over the stock dll that was with the repo.

seems that solo mining with home computers can be profitable again? ;)

Has somebody found any block with this miner yet?

5 and counting. Literally just got one 23 minutes ago.

How many PCs you got?

Currently running 6 cores on (1) i7-4770 and 7 cores on (12) i7-3770. I save the last core on the 3770s for gpu litecoin mining overhead.

Quick question: is the chainsperday stat on the datacoin daemon supposed to give a reading when you are using an external miner?

I'm just wondering because mine is sitting at 0, other than that everything seems to be working correctly. I got a big boost from using the Sandy Bridge mpir on my i7 4770 as well.

No. The chains per day stat is generated by the internal mining code of the wallet.

wooow, how much times when you get 5 blocks on these PCs?

And what's the "ACC" mean?

linux pretty please?

I'm still fighting with the native Linux version but meantime I would suggest running the windows version with wine

I was mining with jhPrimeminer for the last 24h with 6 PCs (core i5-i7). Found two blocks, or in other words paid as much for electricity as the coin value is (probably even a loss). Don't know if jhPrimeminer is the cause. Was mining with datacoind 2 weeks ago (diff was less) and had 6 blocks with 6 PCs in 24h.

2 weeks ago diff was much lower...

I've just checked the logs, the diff was 9.6.

Hey guys,
I'm having trouble getting this to work?
I've created a datacoind.conf file and put it in the datacoin directory.
I've added:

server=1
rpcallowip=*
rpcport=9199
rpcuser=USERNAME
rpcpassword=PASSWORD

to it and added a .bat file to the miner's folder with this:
jhPrimeminer.exe -o http://localhost:9199 -u USERNAME -p PASSWORD

It crashes with error "GetBlockTemplate mode requires -xpm parameter".
What am I missing? Can anyone give me the proper structure of the jhPrimeminer batch file?
For non-ATX version if that matters.

I got the miner from this link in this thread:
https://mega.co.nz/#!mRMnSAwC!ZoAHgBVIMIOthnRQOq9ukRWWz-hvayNyshB1oXpHcXU
Any help is appreciated.
Thanks!

9.7489277 is much more than 9.6. This difference can lead to 3x-6x less coins per day. Remember that diff is not linear, but exponential

jhPrimeminer.exe -o http://localhost:9199 -u USERNAME -p PASSWORD -getwork

Thanks ig0tik3d, but I already tried the -getwork tag with no success.
with that tag it stays open, but It repeats these two errors over and over:
Getwork() failed with error code 1
getblockcount() failed with error code 1

I'm not sure whats wrong...
I've set the datacoin wallet to setgenerate true 0 and its open...
Any other ideas?

Try adding to the datacoin.conf file rpcallowip=127.0.0.1 then restart the datacoin wallet and run the miner again with the -getwork parameter.

Mumus, any eta on linux version?

Check to make sure that port is open on your router if your miner is on a different network than your wallet.

should be datacoin.conf

Just because you put the port in the datacoin.conf does not make it open on your router. You will need to go to your router administration page (192.168.1.1 for example) , and forward the port to your machine. Remember you will only need to forward the port if your miners are in a different network than your wallet.

Comeon guys, he doesnt need any ports open, he doesnt even need router in theory, hes mining on LOCALHOST - 127.0.0.1

Almost done, still need some extra time because it's not stable. Because I need also some sleep I guess in about 12h I will try to push some sources out.

I would be happy to help if your looking for some beta testers.

Didn't notice he was mining on localhost. I know you don't need to open ports if on localhost which is why I put "if your miner is on a different network than your wallet".

I'm also waiting linux version, want to check some things...

Hi,
Regarding to the Linux miner I've just found out that my last day work was a little useless because tandyuk in his repository already merged the relevant changes to a different branch that works also with datacoin. Source is here: https://github.com/tandyuk/jhPrimeminer/tree/mumu-v8 (https://github.com/tandyuk/jhPrimeminer/tree/mumu-v8)
Building instructions can be found also there. (This version doesn't requires the "-getwork" parameter)
There are still problems with solo mining on the Linux builds in general because of some communication problems with the wallet. Each request to the wallet takes at least 2 sec and the connection is not closed correctly as a result the miner doesn't gets the new block notification in time and also may result in crashing the wallet. I'm working on fixing this issue.

-M

Thanks mumus!

So do I... Wanna try to run it on my 100 ubuntu 10.04 machines  ::)

As I understand, it will be possible very soon ;)

Like this weekend? :)

BTW The mpir package I've linked is not built by me, I've took from Rdebourbon's doropbox. https://www.dropbox.com/sh/sq24hzo993afy9c/l7icP0KiuM
He also got it from somewhere else.
I've also tried to build them with the latest sources and VS2013 but I the test results wasn't so good so I'm just using the dlls from the package. 

Thank you all so much for your suggestions.
Still no go on the miner.

This is my datacoin.conf file:

server=1
rpcallowip=127.0.0.1
rpcport=9199
rpcuser=USER
rpcpassword=PASS

and my .bat file:
jhPrimeminer.exe -o http://127.0.0.1:9199 -u USER -p PASS -getwork

The .conf file is in the same folder as the datacoin-qt file.
Open up the wallet, type setgenerate true 0. Run miner.
Getwork() failed with error code 1
getblockcount() failed with error code 1
getblockcount() failed with error code 1
Getwork() failed with error code 1
getblockcount() failed with error code 1
getblockcount() failed with error code 1
Getwork() failed with error code 1
getblockcount() failed with error code 1
getblockcount() failed with error code 1

Super annoying. What am I doing wrong? Everything looks right...

First you don't need the setgenerate true 0
setgenerate is controlling the internal miner of the wallet. We don't want to touch this now.
To check if your wallet is responding you may execute the following command from command prompt:
telnet 127.0.0.1 9199
If it connects without an error you should see a blank screen, otherwise you'll get some error message from telnet or from the wallet.
(in newer windows Telnet is a feature that you may need to add separately in the "Turn Windows features on or off / Telnet Client")

You should place the datacoin.conf file in %appdata%/datacoin/ not in the place of the qt wallet

Just press the windowskey + R and type %appdata% , this will open a window with some directories, search for datacoin and put the file inside that dir.

Go to your datacoin wallet.dat dir.
Get there fast pressing Win+R on your keyboard and paste there this:

%appdata%/datacoin/

You should be in correct directory now.
Your sohuld see wallet.dat file.

Assuming your datacoin.conf file is where your .exe file is just copy&paste it.

Voila.

checked - it works for me. Waiting for linux :)

I've compiled linux version on 16-core Xeon. Well, it works fast, new shares coming at light speed :-D
But when it found 9-chain share it crashed server-wallet on other Windows machine :-P No reward.

See if it works on testnet.

@mumus:

omw, waiting on testnet nodes... no block sources so far.

I have a fully synchronized node on 84.228.200.63 and I'm also connected to 2 additional nodes: 144.76.123.194, 108.61.57.80.

Now I'm stuck 5 hours behind, 1st node wont connect, others work.
End of work time, I'll check it from home.

5h is OK. that was the last block on the network probably generated by me.

Ahh great, now I feel like an idiot.
I assumed it checked the current directory first.

Hi,

I tried it and it indeed crash the wallet when i'm going over 5+ simultaneous connection from Linux.
Still it look very promising!
Thx you for your work and hope to see the issue resolved soon :).

I have been testing 5 or 6 linux machines pointed at a linux wallet and no crashes yet (only been about an hour).

I am seeing 0 Total/Valid shares from all miners though:

Does that mean that something is wrong or is that just a pool type stat/protocol that doesn't exist yet?

From what I gather, there is no way to see the total hashing power going through a wallet is there?

@mpjetta:

Remember its solo mining, valid share = block found :-)

@mumus:

I've found temporary fix for qt-wallet not closing connections, should work without crash at least longer.
Add rpcthreads=1024 in .conf file.

Tips are welcome :-P

I've had my rpcthreads=64 and haven't had any crashes. I've had multiple 9-chains as well. How often should a 9-chain actually end up in a mined block? Or does that even matter?

anyway to set the number of threads? like -t 4?

Yeah, it seems to be -t

Thanks to everyone for helping me out and thank you mumus for putting in the work on these miners.

Mining 5 hours 10 mins on a quad core x64 machine.
254 x 6ch
24 x 7ch
2 x 8ch
0 x Valid Blocks

I can feeeeel a block coming.

This coin is just begging for a pool!

@mumus & all good people who want to test it:

I just compiled mpir.dll from sources for core2 and nehalem + avx optimized.
Tried to benchmark it few minutes, avx version seems to be even faster than last added to mumus build.

Here is the link to my skydrive:
http://sdrv.ms/19FlJPX

Gl & hf with more shares :-D

I compiled the same one, but it wasn't as fast as the Sandy Bridge mpir on my 4770k

我根据你说的做了
I do according to your said

I'm completely new to using miners like this and having to set it up with the conf file. I tried reading through this topic a few times, and using the settings MrMagic posted, but it's not starting up; the miner just instantly opens then closes.

Is there an idiot proof newbie guide on how to set up the conf file to make it connect with the jhPrimeminer?    :-*

@KovaFchina I am unable to view the pictures you posted. I assume you are having problems, but I cannot tell what.

@ahnonamis Usually when that happens it is a problem with the command line input. I assume you are trying to start the miner using a batch file since you said it opens and closes instantly. You can view why the miner is closing by open a command prompt and change directories to the one where your batch file is at and running the batch from the command prompt. You should see the error output.

Add pause in next line in your .bat file - you will see errors, as that window wont close.

How to compile miner on linux? (ubuntu 13) Thank you.

Well,
1) download source
2) cd jhPrimeminer-mumu-v8
3) make
4) jhprimeminer will show in directory where Makefile is.

voila :-p

For better results try to make mpir lib from source with gmp compat (at least it worked for me that way)

Oops) i think you compile this source https://github.com/hg5fm/jhPrimeminer
ok thank you.

what need to do ?(for noob)

...
And now? lol... Someone with same problem?

@Hix:
 
This is linux version: https://github.com/tandyuk/jhPrimeminer/tree/mumu-v8 (https://github.com/tandyuk/jhPrimeminer/tree/mumu-v8)

Download mpir from official website, unpack;

been mining for around 24 hours with no blocks yet.

icore i7 4770 8  cores with hyperthreading


how is anyone else doing?


I don't have a coin yet, if someone wants to donate one to me, be much grateful.

Is there an easy way to compare the datacoin-hp PPS with the jhPrimeminer PPS?

In datacoin-hp I get 3770 PPS and in jhPrimeminer I get 60000 PPS.

just got a block  ;D

10.46dtc

Primes per second is a bad metric to measure your speed. Since the two miners calculate the stats of your mining differently it is hard to compare the numbers. The way that I measured performance was by running each miner on testnet for 3 minutes and then counted how many blocks each miner got.

Couldn't get testnet working. Will have a look later tonight.

So does this miner works for solo mining on linux or not? I am pretty noob but i want to mine with this guide here  https://bitcointalk.org/index.php?topic=345209.0 on DO but using the external miner. Is it possible or i am wasting my time?

I have been soloing with this miner for 3 days now with decent success. Day 1 - (6) blocks, Day 2 (4) blocks, Day 3 (3) blocks. Total of 137 DTC after 3 days.

Hardware - (6) HP BL460c G6 Blade servers - 96 logical cpu cores (16 per host including hyper threading) Windows 2008 Server X64.

3 blocks/last 24h (linux+win mixed + around 50cores total)

What was your result?

I am having trouble port forwarding.

ipconfig

I tested a few days ago before mumus posted about using different versions of mpir.dll. I was using the one included with the repo at the time, which had lower performance for my machines. Anyway, the results at the time were about 93 blocks for external and 130 for HP miner. Since then though I have been using the sandy bridge mpir.dll, which gave me a big boost in performance for the external miner. I have not tested since upgrading, but my chains/h was about 3x higher using the sandy bridge dll over the default, so I assume the external is faster with the right mpir.


Do you have the correct port in your datacoin.conf file? Eg. rpcport=9199

Yes, I can mine on local host.

Hmm. That's a tough one. You can open other ports fine on your router?

How many DTC blocks this machine can mine? http://www.forbes.com/sites/alexknapp/2013/11/21/china-still-has-the-worlds-fastest-supercomputer/

Has anyone gotten an AVX version to run with GPool? Non-AVX speeds are killing me.
