[Datacoin] External miner released!

[maxsolnc]

Hi community,

I'm glad to say that mumus released his version of jhPrimeminer there: https://github.com/hg5fm/jhPrimeminer

Yes, the hg5fm is my repo and of course you can use the miner and the code freely.

MrMagic gave us this link and additional info about mining:

The only changes I had to make were adding transaction.h and transaction.cpp to the project and setting useGetBlockTemplate = false. I compiled using x64-AVX in Visual Studio 2012 Express.

To start mining you need to open the debug console on your server wallet and put "setgenerate true 0". Now you can point your miner at the wallet and start mining.

I tested on testnet with a few PCs and watched the mined blocks roll in. I have been running on mainnet on all my PCs for about 24 hours and I mined one block so far.

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:

This code was originally written and forked from the repository of jh00 (the owner of ypool.net). <...>
My DTC address is: DUEXtM7PGck5rLWmVPo8CTPSrRHXiv5UGW

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.

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?

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.

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

Also can you give information on how to compile?

[ig0tik3d]

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?

[MrMagic]

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
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?
