CCminer(SP-MOD) Modded GPU kernels.

[sambiohazard]

When mining ETH has anyone worked out how to use only certain GPU's, -d does not seem to work.  Trying to just use the 970 on my mixed rig.  I have messed around but can only seem to use 1 card or all of them.

ETHMINER--

Ethminer is not CudaMiner or CCminer.  By default Ethminer only uses card 0.  To use specific cards, put the command:

    ex.1)  "--gpu-devices 0 1 3 4"   or  ex.2)  "--gpu-devices 2"

on the command line.  The first example I gave will skip card 2, the second will only use card 2.  Don't use commas between the numbers, that is CudaMiner or CCminer format.

I am afraid that SP_ might be upset because of the Ethminer chat, it is off-topic.       --scryptr

I disagree, this is Cuda miner bonding time... :p

That and I'm sure if this generates interest, SP will want to get in on it too. The current Ethereum miner is mainly OCL so Nvidia cards all suck compared to AMD, they aren't running Cuda code for the most part. A 280x gets 25MH/s, while a 970 gets 17MH/s... SHAME! If only there was a Cuda coding hero that could rescue us~

ETHEREUM--

Ethminer is part of a much larger networking (group computing?) package called Ethereum.  Anyway, the miner itself is a small part.

Further, the Windows compiled version (~v1.0) that CryptoMining Blog distributed has a bug that affects 750ti cards, reducing their hash rate to 1-3Mh/s from about 8Mh/s.  Mine get about 1Mh/s.  An older version, v0.9.3, supposedly still works at the higher rate, but I can't find the code or an executable. One user said he compiled it on Ubuntu 14.04, and his rig runs fine.  My 960s run fine on Windows with v1.0, but the CUDA toolkit that Gemoil, the dev, used is a mystery.  He supposedly moved to v7.5, and no longer has v7.0 dependencies.  It is not known if the miner will compile on CTK v6.5.

The code has some dependencies not used in CudaMiner or CCminer, that might be problematic for a CCminer port.

I encountered a weird bug. When trying to mine with ethminer I get 'out of memory' when trying to start it up on one of my machines. Using the --opencl-device and --opencl-platform flags don't change anything. It refuses the use the 970s even though they show up with --list-device and obviously they have enough video memory on board.

Something else I noticed. I tried a older version of the miner and it makes a dag and then starts trying to mine with my AMD-4250 (integrated graphics). The switches for devices and platform once again do nothing. Weird thing about this, the 4250 isn't even in device manager and the motherboard isn't reporting it as it's disabled!

I noticed a cuda switch with a older version, trying that now. Either way the platform options seem to be broken.


Edit: seems the cuda switch works, however the miner eventually crashes after trying to regenerate the DAG file while it's mining. It also mines at close to nothing as utilization is through the roof. My 8350 with a handful of cards uses like 40% for 3x970s for comparison.

MANIA--

The coin is being hyped by some brazen blog-spammers, but the Ethereum project is bigger than all that, and appears legitimate.  If the coin (ETH) goes to a stable $3-$5 like LiteCoin and DASH, a single 6-card rig of 970s or AMD 280x cards would be profitable.       --scryptr

Right now AMD rigs are very profitable... makes me hurt inside when I think about having sold mine and downsized to Nvidia hardware. Hindsight is always 20/20 though. We'd all be millionaires if you could see the future.

I agree with you but for small time miner like me with just 1-2 cards, it doesn't make much sense to mine solo with 20Mh/s against 80+ Gh/s. Unless a pool is available its good for everyone to be divided between VTC & ETH. Also, there is speculation about the premine worth 17% of supply, unlimited/no cap to supply & most importantly not much development yet on smart contract side. ETH is something you mine/buy now and stash for a year or two. A long term investment with all the risk although Vitalik is very intelligent & i am sure we will see something from him in the future.

[UserAlter]

It looks like mining ETH is currently the most profitable.
100 750Ti could get 1.15 BTC/day.

why are you all counting in 100 or 1000 of 750ti ?

Because it only needs 120000EUR to buy 1000 of them + a little powerplant and You are making big money

Someone is very unhappy with my sharing about ETH mining.

SOLO MINING ETH--

I started solo mining ETH yesterday, and am hashing along with about 25Mh/s speed.  I just hit my first block (5 coins), the rest of the week I may see nothing, but on average I could get 10 coins.

I am hashing with my "lame" rig.  I hope that it is only a riser cable, but there is a card that kicks out and crashes the Win 8 x64 system.  If it weren't for the 750ti hashing bug, I'd be hashing at about 50Mh/s.  The rig runs Ethminer smoothly, but crashes on even VTC with CCminer.       --scryptr

@scryptr @antonio8
deleting the DAG corrected low hashes for my 750Ti
you could try that.
@fenomenhaa
15 280x would make a lot for ETH mining

[sp_]

Ok, I have checked the etherum hashing code.
I think can optimize kecaak implementation 40-100% faster than the current cuda implementation
But... New protocol. Alot of work to integrate to ccminer. No project file for windows.

It is really nice to hit the first block with just 1 280x hash.

#GreedyNoob #SelfishMiner

I just knew it would be pasted there

As you can see I am a noobish user

Anyway right now both vtc and eth are more than profitable for mining(atleast here with power cost 0.12EUR/kWH).
My numbers with 4x970+960+750ti:
51.5MH on vtc with ccminer (also accepted on give me coins pool)
85MH on eth with cudaminer (on eth pool), network hashrate reported 230GH-https://stats.ethdev.com/
The gpu power usage and the temps are much lower on eth ---> some big gains by code optimization seems possible

For comparision r9 280x is reported to have ~24MH on eth.

The later eth-cuda miner let's you select cards with - -gpu-devices 0 2 3

This only works with eth-cuda on the latest 2 or 3 releases.

If using regular eth (opencl) it will not work. Use - - opencl-platform 1 and all cards will be used.

I just started it like that (opencl-platform 1) and it doesn't look much different: https://i.imgur.com/3SDe7Bw.png
It looks like it's mining AND it's building a DAG file? Are DAG files per card?

I believe diag is per card don't quote me though.

If using AMD cards try - - opencl-platform 0

I DELETED THE DAG--

It didn't help.  I am on Win 8 x64.  Are you running on Linux?  A fella on another blog said he installed Linux (dual boot) and the problem went away.  Linux means that you have to compile with Ethereum in place, as well as the Cuda Tool Kit.

I am thinking of reloading Linux on my rig.  That fella said his 750ti cards were getting 9.5Mh/s.       --scryptr
