Need tutorial on how to add new Algorithm

[mosesong]

Can we get some tutorial on how to add new algorithm to our miners(i.e. ccminer)? Been waiting for Xevan and now there is new x16r algorithm out that we PimpOS users can't use. It's very frustrating because we don't know when the new algorithm is coming to PimpUp, and the longer we wait, the more profit we would loose since some of use try to mine those new coins before the difficulty goes up.

Thanks!

For ccminer, the process is very simple. You can get a pretty good tutorial here:

First, make sure the current build supports the algorithm you want to use. As of today, the list for ccminer looks like this:

  -a, --algo=ALGO       specify the hash algorithm to use
			bastion     Hefty bastion
			bitcore     Timetravel-10
			blake       Blake 256 (SFR)

			x17         X17
			wildkeccak  Boolberry

Next, create a user profile. Declare the algorithm as desired, setup the pool and wallet info, and fire it up in debug mode first to make sure its all working as expected.

Thanks, but that's not what I'm asking for. I see that CCMiner 2.2.5 already support x16r, don't know when we will get 2.2.5 in PimpUp. However, there is a "ccminer-xevan" out there, how can we add it to our PimpOS?

[Anjin]

If you look above, you will note that the currently shipping version of ccminer supports x16r, and the version reports 2.2.5.

*** ccminer 2.2.5 for nVidia GPUs by tpruvot@github ***
    Built with the nVidia CUDA Toolkit 9.1 64-bits

So I am just a little confused by your request. Could you clarify? The version of ccminer currently shipped is 2.2.5 and supports x16r. When you do a pimpup and update ccminer, it will fetch the current mainline source code from GitHub, and compile it up on your rig.

======= Starting update for nvidia-ccminer
-> Backing up existing /opt/miners/ccminer to /opt/miners/ccminer.03-12-1453
Source type is: git
-> Cloning -b linux https://github.com/tpruvot/ccminer to /opt/miners/ccminer
-> Updating submodules in /opt/miners/ccminer
-> Executing autogen.sh
-> Executing 'configure '
-> Executing make... This is the actual compiling and it may take up to 30 minutes on some systems. Typical compile time for sgminer is about 5 minutes, ccminer about 15 minutes.

As for the ccminer-xevan, there are multiple forks of the ccminer code base where third parties have added in xevan. We do not normally support many of these forks. By adding in a new algorithm to an existing miner, many third parties will also subvert the dev fees. This is not a good practice and impacts the original developer teams.

Regardless, the PiMP environment allows for you to simply pull any fork you desire, and build it following the maintainers instructions. 99% of the time, most trees will build without any issues. Occasionally you will need to resolve some dependancies. Once you have build an unsupported fork of a supported miner, you can simply replace the binary. IE, put the new ccminer with xevan into the directory /opt/miners/ccminer as the file ccminer.

The best resource for doing this is simply the GitHub repository for the miner fork you are working with.

Thanks! For some reason I thought the CCMiner we have in PimpOS at the moment is 2.2.4, could be because of the post here https://forum.getpimp.org/topic/10/setting-up-miner-profiles/2 stating 2018-1-25. I will run PimpUp on my system again later today and try out x16r.

when we will get sgminer x16r for AMD GPU

[lily]

We dont write the miners, so we dont know when a particular miner will support any algo.
If SGMiner currently does not support x16r on AMDs, it would be up to the authors of SGMiner to include it.
