Cgminer Hardware Performance

running benchmark on my Nvidia GTX 670 I get a cool 400 Mh/s [win8.1 64]

Edit: actually ~397

 

Did benchmarks on a few graphics cards I have I'll update when I get the third one set up

AMD Radeon HD 4850, 275Mh/s (Win Ser 2008 r2)
Nvidia Geforce GTX 460, 148.8 (Win 7 64)
Nvidia Geforce GTX 970, 1.172Gh/s (Win 7 64)

 

So... Linux documentation needs a bit of help, and I may have a bug.

1) On Ubuntu, and perhaps others, you need to force the shared library. (LD_LIBRARY_PATH=. ./cgminer --blake256 --benchmark)
2) You need open cl installed and accessible. It is driver version specific. Check with; (ldconfig -p |grep libnvidia-opencl)
3) Another dependency is libssh2. (On Ubuntu 14.04.3 libssh2-1)

4) Headless operation is NOT working.

Code:

lee@dev01:~/Downloads/cgminer-decred-linux-x86_64-20160127-v3$ LD_LIBRARY_PATH=. ./cgminer --blake256 --benchmark
Error opening terminal: xterm.

This is with ssh with x tunnelling enabled, however "gedit" also does not work, so it may be this crappy VPN I am on. (xeyes did, and xterm comes up after significant delay so the tunnel is up) But I do not think a hard dependency on x tunnelling from a headless server is a good idea. I will try again tomorrow night when I get back home.

 

What are the dependences.

 

try exporting TERM=xterm-basic, that worked for me[/QUOTE]

 

@jolan, I can try to help with Ubuntu, don't worry.
On a similar note, I'd love to be able to help by providing binary builds for Ubuntu and / or Fedora in the future

 

Here's the results from 2 of my cards:

Nvidia GeForce GTX 660 Ti = 274 Mh/s
Nvidia GeForce GTX 980 Ti = 1912 Mh/s

 

Nvidia GeForce GTX 760 354.5Mh/s

I cant get my R9 380 to get recognized yet. Still playing.

 

Seeing some nice results here. Remember to also post them on http://www.mininghwcomparison.com.

 

Nvidia Quadro 4000 111Mh/s

 

Statically link the thing - the OpenCL stuff uses the ICD on the system anyways.

As I suspected, the code can get better - but on GCN cards, not much faster. Well, not using traditional methods. Time to try a new tack - but I'll need to modify cgminer itself to do so.

 

Guys what version of ccminer are you using to test speed on nvidia cards?

 

They're probably using cgminer.

 

Or a modded CCminer

 

cgminer 3.7.2 for testnet.

 

Thanks Wolf. cgminer works just fine. but seems like 750Ti not so fast.
485mh\s.
i hope there will be improved ccminer version...

 

2 x GTX 980s here. Combined rate for both is 2.806Gh/s

 

OK testing mining with cgminer, only getting less than 50% of hashrate that i get on ccminer for 14 round blake. Good to test but not so good for mainnet. I hope we see modified ccminer for decred before that. Maybe @Wolf can help with that too.
GTX970 hashes at 1.05GH/s
GTX750ti hashes at 405MH/s

EDIT: ok managed to improve hashrate to

GTX970 hashes at 1.11GH/s
GTX750ti hashes at 431MH/s

by setting intensity to 10 on both cards. It took me 47 mins to find a block and 22 mins for second. Lets see if i get the balance after 16 confs.

 

Is anyone succeed to build cgminer for Mac OS X?
