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

[RTM88]

Hi, I have been looking for a script to autorestart ccminer or autoreboot the pc, do u know where i can find one? one more thing also looking for monitoring software for multiple miners using ccminer (windows).  I have used monitorig before when i was mining eth but it does not work with ccminer. Thanks

I can't get this to work on a 19 card rig. =( Have to remove cards down to 16 cards to make it work.

If anyone is interested I ran some benchmarks using 2.2.3 in under volted, default and Overclocked conditions.

Great job!
But why 65%? It seems if run with 75-80% power you'll get better results

Does anyone know if mining Vert coin and Mona coin with ccminer 2.2.3 and suprnova require more GPU core clock, memory clock, or both?

For eg. I know it's more important, for Ethereum, to have as high memory clock as possible while with Decred, last I heard, you lower memory clocks because Decred only uses the core.

So what's the best way to go about with Mona and Vert Using Nvidia GTX 1070s?

the answer is 2 posts before, common :p

there's the problem:

Code:

gencode=arch=compute_20,code=\"sm_21,compute_20\"

CUDA 9 doesn't support this anymore.
Try using the cuda9 branch.

how do I go about installing cuda9 branch on Ubuntu 16.04? I downloaded latest Cuda from
https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&target_distro=Ubuntu&target_version=1604&target_type=deblocal

You already have CUDA 9 installed.
I mean the cuda 9 version of ccminer.

hello all,

I'm facing a similar issue. I have Ubuntu 16.04 running with CUDA 9. I'm trying to compile the latest version of ccminer and I get two errors:

/usr/local/cuda/bin/nvcc  -I. -I/usr/local/cuda/include -O3 -lineno -Xcompiler -Wall  -D_FORCE_INLINES - gencode=arch=compute_20,code=\"sm_50,compute_50\" -o scrypt/salsa_kernel.o -c scrypt/salsa_kernel.cu
nvcc fatal   : A single input file is required for a non-link phase when an outputfile is specified
Makefile:2253: recipe for target 'scrypt/salsa_kernel.o' failed
make[2]: *** [scrypt/salsa_kernel.o] Error 1

make[2]: Leaving directory '/home/laurent/Desktop/Mining/ccminer-1.8.2-tpruvot'

make[1]: Leaving directory '/home/laurent/Desktop/Mining/ccminer-1.8.2-tpruvot'
Makefile:578: recipe for target 'all' failed
make: *** [all] Error 2

In my makefile.am I have:
nvcc_ARCH  = -gencode=arch=compute_50,code=\"sm_50,compute_50\"
nvcc_ARCH += -gencode=arch=compute_52,code=\"sm_52,compute_52\"
#nvcc_ARCH += -gencode=arch=compute_35,code=\"sm_35,compute_35\"
#nvcc_ARCH += -gencode=arch=compute_30,code=\"sm_30,compute_30\"
#nvcc_ARCH += -gencode=arch=compute_20,code=\"sm_21,compute_20\"

the compute_20 is not enabled but I see later on:
scrypt/salsa_kernel.o: scrypt/salsa_kernel.cu
$(NVCC) $(JANSSON_INCLUDES) -I. @CUDA_INCLUDES@ @CUDA_CFLAGS@ - gencode=arch=compute_20,code=\"sm_21,compute_20\" -o $@ -c $<

Somehow it seems to force the compute_20 even if it's in comment at the start of the file.

Any idea of what I should do?

Thanks

Follow what Schleicher said that should fix your issue.. thanks again Schleicher!!!

[klintistwood]

Thanks, it was right in my face

I tried to compile it and everything went fine, now trying it with cryptonight to compare with the previous version...

[klintistwood]

I have tried cryptonight and my hash rate is almost one third of what I used to have with the previous version. I have also tried lyra2rev2 and I couldn't even start the miner, I get: Segmentation fault (core dumped)

[Epsylon3]

-f, (and -m) will change nothing for you.. except doing problems -f 2 will reject half the shares, -m 2 will not submit half

[joblo]

-f, (and -m) will change nothing for you.. except doing problems -f 2 will reject half the shares, -m 2 will not submit half

What about -m 0.5? Will that submit twice as many?

I have no idea what the real puspose is, probably a relic from the early days of Bitcoin. Certain reject reasons
will trigger an automatic change to -f but they never helped in my experience.

There may have been a time where a pool was misconfigured for a time and required -f to get shares accepted,
but then the pool was fixed and it was no longer needed.

[Epsylon3]

was for a few alien pools... and keccak which didnt had really a standard 128 vs 256 regarding the pool :p

-m 0.5 = -f 2 but well... integers

[aundroid]

When mining lyra2rev2 with multiple GTX 1070 it works for some hours and then suddenly fails with
"unspecified launch failure"
I have already lowered the intensity and power level  ....
Any ideas?

[lorddefenser]

Good Morning, someone can help-me?

I'm have 2x 1060 and 2 1070 using Simplemining.

I config the miner to use lyra2rev2, but don't work, get error.
Already checked my worker, and lines configuration a milion times.

Help-me?
