Topic: [Datacoin] External miner released! - page 6. (Read 10520 times)

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

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= (whatever port you choose to open for the miners to connect to your wallet)
rpcuser= (whatever username you want)
rpcpassword= (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.

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

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!

Is it just me or is the forum broken?

thanks a lot kind sir

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

what is command line for solo mining?

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

Also can you give information on how to compile?

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

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.

do you know how to compile it under linux ubuntu?

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

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

Thanks!

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.

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

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

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