Submitted another speedup.

Atomiccas is faster than atomicexch. Quark is up another 50khash on the 970

I have reached 18.1 MHASH on the 970 now. That is faster than many 980 cards..

Very nice, when it will be compiled at git releases ?

Usually I build 1 time per week.

Not mining Quark right now, but beautiful as always. I have noticed that electricity usage is slowly creeping up. I think it's gained 20w over the last 3-4 months...

This is a bug T Nelson is good at finding..

Solomine in a testnet with low hashrate. Probobly a division by zero or something in the hashrate statistics.

Someone hook me up with a precise test case and I'll take a look.  Full command line should do it.  Yes, I'd rather mine for you than bother setting up accounts.

WALLET--

You would be solo-mining with your own VTC wallet.  My wallet is not open to the web; lag would likely ruin the setup anyway.

My configuration file for a single GTX 960, saved as solo-vtc.conf:

-- SNIP --

My batch file, saved as "solo-vtc.bat":

:loop

ccminer.exe -c solo-vtc.conf

pause
goto loop

My Vertcoin wallet configuration file, saved as "vertcoin.conf" in ...appdata/roaming/vertcoin under the login user's name:

-- SNIP --

The example IP of the server in the miner's configuration file must match the LAN IP address of the computer with the VTC wallet.   You don't need to assign a port in the wallet configuration file, "5888" is the default VTC RPC port.  You must name the wallet configuration file "vertcoin.conf" for it to be found by default.  This particular setup is for the VTC wallet computer, and the GTX 960 on the same computer.  I ponted my other rigs in my LAN at this same computer with no problem in communications.  Each rig crashed at least once.


--scryptr

Should I be expecting any output from ccminer when soloing VTC?  I'm on linux and, from what I can tell from the debugger, it seems to be hashing.  But there's no output on the command line after ~5min.  Of course it spits out a couple lines right after I hit post.

How long does it usually take to crash?

Since a few releases I do not see hashrate for each card, only the total hashrate is displayed.
How can I change this?

This is my output, 1X970 and 1X750ti:



Thanks!

HASH RATE--

The result depends on the hash rate.  When a block is found, it crashes, according to CryptoMining Blog.  If you are testing with one 750ti, that may mean several days.  My rigs combined total hash rate is enough to find 2-3 VTC blocks a day.  The crashes happened at a frequency consistent with the rate at which I should be finding blocks.  The hash is directed at the wallet, so the combined total of all the hashing directed there determines the probability of finding a block.  At CoinWarz.com, you can find a mining calculator that will tell you an average block-finding rate for all the coins listed.  VTC is one of them.

Something happens when I should be getting an "accept" message.  The cards hash and communicate with the wallet until then.  Hashes are "submitted", you get the card's hash rate in the console output.

[qqqq]

Very strange case about crashing when block is found cause we also mine with same version through the nicehash, but it's some sort of collective solo (sounds strange) i guess. They have same wallets or daemons.

Is there a version of this for mining cryptonight algo?  I have a GTX 970 that I want to mine with but I can't find any miners that work with the Maxwell cards.  Minergate doesn't work, tsiv doesn't work, is there a Maxwell kernel miner for cryptonight algo notes?

TSIV's works, as well as sp_ has a private version with some small boost (windows binary only).
What trouble are you having with TSIV's?

OK I'll just leave it run in the debugger with a 960 and 750Ti and see what happens.

Thanks!

Does your command line contain "-q" or "--quiet".  Sp_ fixed quiet mode back in release 65, so if you have either of those switches you will only get total hash rate displayed.

Guys what i'm doing wrong...
git clone https://github.com/sp-hash/ccminer.git
./autogen.sh
./configure.sh
everything is fine here.
but when i try to make:

Code:

/usr/local/cuda/bin/nvcc -gencode=arch=compute_52,code=\"sm_52,compute_52\" -gencode=arch=compute_50,code=\"sm_50,compute_50\" -I/usr/local/cuda/include -I. -O3 -Xcompiler -Wall  --ptxas-options="-v" --maxrregcount=128 -o heavy/heavy.o -c heavy/heavy.cu
nvcc fatal   : Unsupported gpu architecture 'compute_52'
make[2]: *** [heavy/heavy.o] Error 1

i'm using GTX 750Ti card and

Code:

You should also be compiling with the script ./build.sh included in the repo.  It adds the correct compiler flags to produce a higher performance binary.

Hey there, thanks for responding!  How do I get the private version?  TSIV keeps giving me the error: "result for nonce $000LETTERS does not validate on CPU!"



I tried a few -l values that make sense but I'm not sure how else to try to fix it.

Are you ciompiling with cuda 7 or 7.5? use cuda 6.5.

My private miner is doing 500h/s on the 970. (0.1+0.1BTC donation is required)
0.1 for the spreadcoinminer
0.1 for the cryptonight miner.

I'm not compiling I'm just downloading the binaries.  Is this downloadable version of SP-MOD able to do cryptonight algo?  or are you saying it's another mod?  Is spreadcoinminer something else entirely?

[sp_]

It's 2 other mining software.

The spreadcoinminer comes with full sourcecode, the cryptonight is a windows exe only.

is lyra2v2 broken in v67? ...

on givemecoins - there seems to be no shares being created or submitted ...

--diff .5 is still being use on that site though ...

Thanks for the offer but I downgraded my driver and now I am able to use TSIV's miner.
