CUDA miner

Mo35 · February 2016

Im bit stuck with latest 1.0.3 miner , unfortunately i had to slice up partition to fit win7 for mining purposes , and i have limited amount of disk space , so 1.0.3 versions DAG loc switch is must for me. i have 970 and 2x 950 cards , but with --cuda switch im unable to force miner to use all cards it just sees 1st 970 , using --opencl works with all cards and properly announces them as cuda1.2. Any suggestions what im missing ? why with --cuda only 1st card shows up ?

Sergeant · February 2016

@Genoil thank you for a hint. Found August version of ethminer and it works with 3.0 cards just fine.

@restless only with compute 5.2 cards. 750ti is Compute 5.0

@Genoil GTX750Ti under Win7 does not work - this is clear. But is the Linux another story?
Here and there I've got 4 GTX750Ti cards in different PC all under Win7. I wonder will it do any good if I place them into one Linux farm?

Genoil · February 2016

@Mo35 hmm this sounds like a bug. I've read the same somewhere else today. Anyway, try adding --cuda-devices 0 1 2 to the command arguments. This should force the use of three cards.

@Mo35 add "--cuda-devices 0 1 2" to starting config

@Genoil You are fast

Mo35 · February 2016

thanks that did the job , 3 cards 970+ 2x950 nets me close 40Mhz , impressive ! i just wish i can get rid of win 7 , hate it ... i was happily mining with my old 347.52 driver till i got 950 cards , support for 950 cards apeared just in already screwed 355.69 ... maybe sugggestions how to fool win10 to use 347.52 win7 driver for 950 (it does support 960) , probably some inf tinkering or something deeper is necesary ?

Mo35 · February 2016

Well , actually i did managed to force all cards 970 and 950 to work with 347.52 under Windows 10 even 950 wasn't around at the time of driver release.

if anyone wants to tinker , here is what i did , i found under devices my hardware ID for gtx950 , looks something like this PCI\VEN_10DE&DEV_1402&SUBSYS_85551043 , 1402 is model hw identificator , since gtx960 was close pick , i checked in driver inf files for 960 ID , it was 1401 , so i crawled through infs and searched for 1401 id. And then made changes to fool installer, that my 1402 card actualy is one that that is supported , bunch of entries like this :%NVIDIA_DEV.1401%= Section034, PCI\VEN_10DE&DEV_1402 so on.

You will have to reboot in recovery with driver signature verification disabled to install this changed driver , also retarded Microsoft driver update prevention doesn't really works as it should, it still updates nvidias drivers even its prohibited via Contr.Panel\system\advanced settings\hardware\device installation settings, so i ended up making local computer group policies to prevent windows from touching those devices. Hit run type gpedit.msc and go to Computer Config\Administrative templ.\System\Device Installation\Device Installation Restriction and open policy named "Prevent installation of devices that match any of these Device IDs" , go to your device manager and look under you GPU`S details\Matching Device Id for your card ID values (something like pci\ven_10de&dev_13c2 ), enable policy and add your card ID strings to policy , windows wont be able to replace driver for those devices. Reboot , enable net , enable updates , recheck that your drivers sits on 347.52 and you are set to mine under Win10 for now at least with --opencl at full hashpower.

There is one thing tho with --cuda , you wont be able to mine with 1.0.3 unfortunately , because miner crashes with "cuda driver version is insufficient for cuda runtime version" , even if i copy cudart64_65.dll into miner dir , it wont pick it up , probably we need someone on linux to recompile 1.0.3 with older imho 1.1 cuda support.

Anyone ?

p.s. there is older release with cuda 1.1 support around like 1.0.1 ?, ask author , tho it performs worse (~-2-3Mhz from 40Mhz) and lack newly implemented functionality unfortunately , but at least you can mine with cuda not cl

Genoil · February 2016

@Mo35 I think the message means that the binary should be rebuilt with a version of CUDA that was around at the time the 347.52 drivers were released. So 6.5 or 7.0.

If you can do what you did there with Windows, you should try building ethminer ;-)

simply · February 2016

The 350.12 version for Win7 also working on Win10. This is the newest possible, which does.

Mo35 · February 2016

does 350.12 works with full hashpower too ? unfortunately even 350.12 dosnt include support for newest cards , like gtx950 sooo still , inf tinkering is must.

@Genoil , im not much into linux`es , but for thos 3 additional Mhz , and -R functionality i will probably have to look into , i was just hoping someone with setup for compilation can do that less painfully

Genoil · February 2016

@Mo35 you don't need Linux to roll your own ethminer. Building on Windows is a bit botched at the moment, but I'll try to make that a bit more straightforward.

Mo35 · February 2016

@Genoil , could you please point me to "how to" for win , if its available , i will try to mop up something tonight , thats if i figure out what im suppose to do

edit: am i looking @ correct places ?
https://github.com/ethereum/webthree-umbrella/wiki/Building-on-Windows
https://github.com/Genoil/cpp-ethereum

at the moment still kinda clueless what to do with all that besides , installing VS and trying to feed it something to compile

restless · February 2016

I tried mining on Win7 + 750Ti and 347.52 driver - but speed was ~ 700KH/s

PS:
Installed a 750Ti on Ubuntu
tried running ethminer and ...

./ethminer --help
ethminer: error while loading shared libraries: libethcore.so: cannot open shared object file: No such file or directory

even copying lib file into directory of ethminer won't change the errors
Make install runs flawlessly (imho)

@restless this driver workaround is for Compute 5.2 (GTX900 series) on Win8/10.

@Mo35
1. Download and install CMake and Visual Studio 12 2013 (community edition is free and fine)
2. Download and install CUDA Toolkit 6.5 to make sure you don't get the error message (not 100% sure if this is the cause, but there's no performance hit anyway for using an older CUDA toolkit). Make sure to only install the toolkit and not the bundled graphics driver

3. Download or check out the source code from github
4. run getstuff.bat in cpp-ethereum/extdep. This will take a while.
5. Create a directory "build" inside "cpp-ethereum" and go there with a command prompt
6. run cmake -DBUNDLE=cudaminer -G "Visual Studio 12 2013 Win64" ..
7. open ethereum.sln in build directory
8. go to right pane, right click ethminer and choose "Set as startup project"
9. Make sure build Type is "Release" in top toolbar
10. Press Play button in top toolbar
11. Build will fail

Now comes the part where it's botched. There is a file called BuildInfo.h that is only created at build time. It ends up in the build directory, but the VC project assumes it is somewhere else. Navigate to the right pane, open the Buildinfo project and look for header file "BuildInfo.h". Right click to remove it from the project and add the correct file Buildinfo.h from the build dir by "Add existing file to project".

I really should fix this but I'm not very good with CMake..

Build again and it should work.

restless · February 2016

Genoil, 10x for answer but I'm still trying to build it on Ubuntu

DavBE · February 2016

@restless : i am willing to help you build ethminer on ubuntu, you can reach me on #ethereum on freenode

Genoil · February 2016

new 1.0.4 beta release is up. supports stratum mining on coinotron. please note it's a beta release. it's looking good, but it would really help if some of you could test it for a while.

https://github.com/Genoil/cpp-ethereum/tree/stratum/releases

usage ethminer.exe -U (or -G) -S coinotron.com:3344 -O Username.Workername:workerpass

restless · February 2016

any idea why mu Ubuntu compiles athereum but sees no opencl/cuda devices?!
I installed latest NVidia drivers - 352... but obviously something more is needed

barabeku · February 2016

@Genoil does the latest version submit shares for K520?

In windows it didnt submit shares.
Can you test in EC2 g2 linux instance please, does it submit shares?

Genoil · February 2016

@barabeku if it didn't in the previous version, it won't now. If you send me a few ETH I can spend a few hours of debugging on a $2.60/hr AWS console to see why it doesn't work. Yay.

bluebox · February 2016

@Genoil Nice! Will start with 1.0.4 tonight. Coinotron's stratum has been good so far.

Genoil · February 2016

Normally I don't mine myself, but have been running the stratum miner for a 8 hours now without any problems. Hashrate display in the miner will likely show higher values (about 1MH/s extra for my GTX780), but that's just the result of a different way things are handled. @dr_pra of ethpool notified me it also works on ethpool. He also brought to my attention that I still need to implement automatic reconnect on lost connection.

bluebox · February 2016

@Genoil — Didn't work with your usage pattern, tried adding http:// and other typical patterns, but no go... what would I be doing wrong?

well this is how far i got ... with cmake -DBUNDLE=cudaminer -G "Visual Studio 12 2013 Win64" , no ethereum.sln apears in build dir , some kind of errors in cmake logs wich unfortunately means nothing to me

i uploaded small zip with cmakeerror and cmakeoutput logs , in case anyone willing to look at http://expirebox.com/download/78133cd106b51407cf63afc3fc93867a.html

@ genoil

Not mining ETH much anymore but still lurking and just tried out the latest release. Went from about 48-49 Mh/s to 54-55 Mh/s.

The other miner again was an old one from Sept of last year.

restless · February 2016

Any hint how to make ethminer see my 750ti card under Ubuntu 15.04?
I have all drivers installed, ethminer is compiled, but --list-devices returns nothing.
nvidia-settings shows NV drivers up and running, clinfo shows NV opencl active... out of ideas, except starting from scratch

I used https://wiki.tiker.net/OpenCLHowTo#Installing_the_Nvidia_ICD
compiled the example, ./print-devices shows my 750Ti as valid opencl platform
running ./cl-demo 1000000 10 gives valid results, ie OTHER programs do recognize the device, its only ethminer which doesn't ?!

restless · February 2016

Holy shit, I did it

I think it was http://askubuntu.com/questions/541114/how-to-make-opencl-work-on-14-10-nvidia-331-89-drivers that helped - activating nvidia-352-uvm via modprobe

Ethminer --list-devices still doesnt list anything, but forcing via --opencl-device 0 or --cuda-devices 0 correctly finds the card and benchmarks around 8MH/s

real-world "mining" is ~ 5MH/s

Genoil · February 2016

@antonio8 the thread that displays hashrate is now doing nothing but count hashrate, so it may actually be more accurate, actual hashing speed is not better.

@bluebox should be coinotron.com, sorry

bluebox · February 2016

@Genoil Ha, dumb on my part actually - in a hurry and copy-pasted, should've seen that...

Two 970's getting 40MH/s avg, up from 38 on 1.0.3, seems stable. I'll take 5% anytime, thanks! Don't have much eth, but will send a tip someday soon, might just buy some now that it's down.
