[ANN] sgminer v5 - optimized X11/X13/NeoScrypt/Lyra2RE/etc. kernel-switch miner

[kenshirothefist]

Hi,

At NiceHash.com (I'm sure you've already heard about us) we're running a multi-algo cloud mining service and multipool. Thus we're striving to get unified and feature-full GPU miner. That's why we've sponsored the integration of sph-miner + keccak (from cgminer) + x11_mod (from lasybear) + NIST5 algo and some more stuff into unified, runtime-kernel-switching new version of the original official sgminer. sgminer has since then been redefined from "scrypt-miner" to "GPU OpenCL miner" and thus strive to support wide range of algorithms for GPU mining. New algorithms are added over time as well as some new features.

For the record: I'm not a developer of sgminer and haven't contributed any coding for sgminer, but was active in proposing and coordinating new features development. All the credits go to the many sgminer developers, listed here: https://github.com/nicehash/sgminer/graphs/contributors. NiceHash organization took over the initiative to continue development on this widely spread open-source mining software, therefore the most recent source code and releases can be found in the information below.

SOURCE CODE

If you wan't to pull the source code from GIT you can do it with this command:

Code:

git clone --recursive https://github.com/nicehash/sgminer.git

RELEASES

Binaries downloads are available here: https://github.com/nicehash/sgminer/releases

Here you can see the major changes:

News: https://github.com/nicehash/sgminer/commits/master

Please note: sgminer is still in development, you should regularly, so there are might be still some open issues and minor bugs present.

Here is an example of multi-algorithm configuration (you can add many pool-specific options):

Code:

{
"pools" : [
        {
                "name" : "NiceHash_X11",
                "url" : "stratum+tcp://stratum.nicehash.com:3336",
                "user" : "btc_addr",
                "pass" : "x",
                "nfactor" : "10",
                "algorithm" : "darkcoin-mod"
        },
        {
                "name" : "NiceHash_X13",
                "url" : "stratum+tcp://stratum.nicehash.com:3337",
                "user" : "btc_addr",
                "pass" : "x",
                "nfactor" : "10",
                "algorithm" : "marucoin-mod"
        },
        {
                "name" : "NiceHash_SHA3",
                "url" : "stratum+tcp://stratum.nicehash.com:3338",
                "user" : "btc_addr",
                "pass" : "x",
                "nfactor" : "10",
                "algorithm" : "maxcoin"
        },
        {
                "name" : "NiceHash_Scrypt-N",
                "url" : "stratum+tcp://stratum.nicehash.com:3335",
                "user" : "btc_addr",
                "pass" : "x",
                "nfactor" : "11",
                "algorithm" : "zuikkis"
        },
        {
                "name" : "NiceHash_Scrypt",
                "url" : "stratum+tcp://stratum.nicehash.com:3333",
                "user" : "btc_addr",
                "pass" : "x",
                "nfactor" : "10",
                "algorithm" : "zuikkis"
        }
]
"failover-only" : true,
"failover-switch-delay" : "300",
"queue" : "0",
... other configuration settings ...

Of course you can choose any and as many pools you prefer, NiceHash.com pools were given just as an example. Your miner will be able to switch to different pools using different algorithms at runtime, without any interruption and without sgminer restart. You can also set GPU settings and some other settings at a per-pool level to get optimum performance on various pools with various algorithms with a single configuration file. Now you can mine Litecoin, Dogecoin, Vertcoin, Darkcoin, Maxcoin, MaruCoin ... you-name-it with a single unified sgminer.

Note: sgminer v5 intoduced new stratum extranonce subscription; some pools ignores connection when sgminer sends extranonce subscription request, therefore you just have to add "no-extranonce" : true setting to the pool config for pools, that doesn't support extranonce-subscribe - this kind of pools appears Dead even if they are suposed to be working fine (you should never use this setting on nicehash pools since nicehash stratum proxy provides better efficiency with extranonce subscription)

Code:

	{
                "url" : "stratum+tcp://some-pool:3333",
                "no-extranonce" : true,
                "user" : "username",
                "pass" : "x",
	}

Or if you're using command line options, example for quark mining:

Code:

sgminer --algorithm quarkcoin --no-extranonce -I 18 -g 1 -w 256 -o stratum+tcp://some-quark-pool:3333 -u ... -p ...

All interested developers, please, feel free to contribute to the code by simply pushing Pull request to the Github repository (see above).

Again, thanks to all the great developers of sgminer and kind regards,
kenshirothefist

YES!!  This is exactly what I've been waiting for!  So, as I'm understanding, do we omit the global kernel option and only need to specify the pool-algorithm?  Or do we list all the kernels we want to use in the global kernel option, then specify an algorithm per pool?

[ekoice]

excuse me, you should add this kernel also : x13 if you want to make it competitive...

[dhsc19]

Isn't marucoin the x13 kernel?

[cryptocointools]

I think so

I can merged mining altcoins (LTC,DOGE,...)? or am i wrong?

[atp1916]

I can merged mining altcoins (LTC,DOGE,...)? or am i wrong?

This release just means you can switch between entirely different algorithm-based coins on the fly, i.e. your main is a Scrypt pool and your fail-over is a x11 pool.

I'm actually hoping to use the pool quota option to apportion my GPU hashing to mine scrypt and x11 simultaneously.  Rather, I'm assuming it does it in a round robin fashion?

[reza_abay]

How can I configure my miner to work with NiceHash service?
I mean config 3 algoritm (scrypt-scrypt-n-x11) in one sgminer.config file.

[n2nshad0w]

How do the speeds compare to the juiced up version being used?

[Glizlack]

Been waiting for something like this since i started mining!!!  Yes about x13 is that going to work as well?

         }
]

Just add your pools and algorithms to your config

[merc82]

Spouting off some random thinking here, how about a stratum protocol amendment -- introducing an algo definition on connection and allowing algo changes to be initiated from the remote stratum.. that'd be fantabulous for us multipools who run multiple algos

[phzi]

Fantastic addition to the sgminer code base.  Thank-you for supporting this open source project, NiceHash team!

Maybe it's time to rename this branch of sgminer to clminer, or something to reflect it's broad utility for OpenCL mining.

[Bojcha]

Well it's  nice but You all are forgeting one thing..
All algos can use different clocks/voltages (for-more-speed)..  atleast I prefer for my 280x 1030MHz for scrypt/n-scrypt and 1100Mhz for X11/x13m.. etc. So this pool list with different algos  has no meaning since i again need to manually switch clocks.

Maybe to make it fully automatic, whole conception of sgminer-confing need to be changed.. something like 2, 3 or more configs that will be used. (config1, config2.. etc.) where config1 is priority1 and config2 is priority2.. etc.

Read the docs, man!  Pool/algo specific clockrates, intensitities, fan speeds - it's all there.

Options that can be configured have a pool- prefix and work the same as the global settings:

pool-algorithm
pool-nfactor
pool-intensity
pool-xintensity
pool-rawintensity
pool-gpu-engine
pool-gpu-memclock
pool-gpu-threads
pool-thread-concurrency
pool-gpu-fan

It would be nice to convert the config format entirely to have maybe an algorithms section with per-algo tuning, instead ofnper-pool. But, you can replicate the same thing easily enough already.

pls put one simple  config file for mininig in NiceHash.com here.

[platinum4]

Count me in, I've been collaborating with Elun, lasybear, and RRT5ON on that previous stripped out x11mod (from girino's 2%) and the newly smashed together x13mod.  I'm getting the tools for Windows builds right now and will see if I can pass a few patches into this.

Multi-algorithms aren't simple... you're going to need to tune your cards separately for each algorithm.  Then, you can calculate the comparative output of each algorithm, probably account for power consumption differences, and from there determine profitability targets.
