[ANN] ccminer 2.3 - opensource - GPL (tpruvot)

[Epsylon3]

Beware both x64 and x86 cant run in the same folder... There are 2 dll with the same name but one is x86 and not the other one... Does that help you ?

[IMweasel]

When i tried -D i noticed something today... is the -s 10 supposed to be directly after my login name?
POOL 0: 127.0.0.1:44101 USER x -s 10
I would guess it is a scantime flag,but no matter what i set it to,the s 10 persists to be there.
And also,if i use the -s flag,the actual scantime does not change at all.

[Epsylon3]

was just a debug line for my recent pool settings... scrypt-jane is so slow that the scan time is almost ignored... Its an extreme test...

Please i dont want to talk about this algo, i imported it to have it and do some compatibility tests/bench... will not touch it for the moment

Hi I'm having some problem with this miner. It doesn't run on my Windows 10 Technical Preview. Always gives the message "ccminer has stopped working" even running the miner with no arguments. Original ccminer by cbuchner1 v1.2 beta works fine in this same OS. I'm using the same config with this modded version and my graphic card is a Gigabyte GT 730 2GB DDR5 using the latest 352.84 drivers for Windows 10.

Run params: ccminer-x64-35-50-52.exe -a dmd-gr -o stratum+tcp://dmdpool.digsys.bg:3333 -u username.workername -p workerpassword

Tested without problems here... Next time please put real credentials, i hate to register on pools for debug purpose, and this one require a wallet address

Sorry maybe I'm missing something obvious but I see only one msvcr120.dll in my install directory. I've downloaded release ccminer-rel1.6.4-vc2013-x64.7z. Also the problem is not related with the pool because the program doesn't even run in my pc, not even with --help param. The exe just crashes not even showing the dos prompt.

Perhaps is related to my videocard not being supported? Is Compute 3.5 Kepler - GK208

Thanks for all the help Epsylon3

P. S. my CPU is an Intel Core 2 Quad Q6700

No.. With these last details... I know why... Avx is required (checked in my build options) if i remember right..

But, just use the x86... Perf are a bit better.. x64 one has no advantages yet... Until nvapi is deprecated (not until nvml is fully implemented by nvidia)

Thanks a lot for the help Epsy, it works like a charm now. 15-20 Kh/s improvement compared with the x64 original ccminer, not bad

Ok...too bad. The UTC founders even recommend -s 1, which works fine for cudaminer...it's still catching blocks just fine, so no need to study them for so long.
Scrypt-Jane  seems profitable for somewhat older cards though, and CCminer is more capable to keep performance high. I wish it would work for UTC  
By the way, the same problem exists for your compilations of the CPU miner,it just cannot do UTC  
I'll give it a rest now...just hoping you can fix it someday... thanks for the swift support!

Edit:original CPUminer is also unable to mine UCT. Trying out yacminer for it,and this one does it flawless!
I figured it might have something to do with this timestamp thing?

Edit2:Pooler stated that is miner does not support UTC. So i guess that any fork without adding specific support,won't work.

This is not working

I have been having this error with my gtx 660se

Code:

cuda error in func'qubit_luffa512_cpu_init' input at line 446, invalid device symbol

ccminer does work with my gtx 770 very well, but i have just not been able to get this to work

this is the batch file for my 660

Code:

ccminer-30-35-50-52.exe -t 2 -d 1 --algo=qubit -o stratum+tcp://stratum.dgb.theblocksfactory.com:9000 -u greedytacothief.1 -p x -f 10

v1.6.5 released today... topic updated

Note: The nvidia-smi tool was updated in the latest nvidia drivers on both linux (352.21) and windows (353.30)

All Clocks, Power in Watts and many other infos are now available, and may be programmable too via the nvml interface... stay tuned.. :p

Getting this error when I try to run on ubuntu 14.04... any ideas guys???

/home/infern0/Downloads/ccminer/ccminer-linux/ccminer: error while loading shared libraries: libcudart.so.7.0: cannot open shared object file: No such file or directory

[Epsylon3]

type ldconfig but your error is really "simple" to understand :p maybe you should use Windows

[nzsquirrell]

Compilation of 1.6.5 produces an error under linux:

g++ -DHAVE_CONFIG_H -I.  -DHAVE_PCIDEV -fopenmp  -pthread -fno-strict-aliasing -I./compat/jansson -I/usr/local/cuda/include    -g -O2 -MT ccminer-cuda.o -MD -MP -MF .deps/ccminer-cuda.Tpo -c -o ccminer-cuda.o `test -f 'cuda.cpp' || echo './'`cuda.cpp
cuda.cpp: In function 'void cuda_devicenames()':
cuda.cpp:79:44: error: 'gpu_vendor' was not declared in this scope
   if (gpu_vendor(props.pciBusID, vendorname) > 0 && strlen(vendorname)) {

Weirdly gpu_vendor is declared in nvml.h, and nvml.h is included in cuda.cpp ..... any ideas?

Otherwise keep up the great work! 

[Epsylon3]

yep, i just fixed it, it was because you dont have -DUSE_WRAPNVML in your build config... didnt fully test this config

its in configure.sh --with-nvml=libnvidia-ml.so

[nzsquirrell]

Cheers for that, builds fine now and has a small increase in qubit hashrate (an extra 3-4 kh/s).

Do you think the skein algo will see any more improvements in speed? It's still pretty weak compared to how an AMD card does (I get ~72MH/s on my 750ti vs. 179MH/s on my 270x).

Thanks for all your work on this

Perhaps it's out of line (then remove it), I would like to make you aware of an auction for six 750TI 2GBs at the moment. Current bid is.... (drums...) 1.51 BTC.

yeah it is 
but it is cheap, epsylon is known to buy all sort of tech junk  you might have already a deal 

[Epsylon3]

nah :p im at the limits of my appartment power supply :p

[erickmontequiary]

So .. I have heard a lot about neoscrypt, however I came a doubt, i'am a friend and we were talking about buying a asic of innosilicon a2 terminator asic, however I have no idea if this works with neoscript .. could they tell me for sure if it is possible to mine neoscrypt with this kind of asic or only with GPU ??
