[Datacoin] External miner released!

[mumus]

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
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.

As I understand, it will be possible very soon

Like this weekend?

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.

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")

The .conf file is in the same folder as the datacoin-qt file.

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.

[MarcusDe]

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

[MarcusDe]

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.

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 .
