Animecoin padding bytes are constant
use echo_final
Wondering if we could mine the coin CREA with the CCminer-13? Uses the keccak-c algorithm which I'm not very familiar with.
Thanks.

Hi,
i got this compiler-error under Ubuntu 14.04 with cuda8:
ptxas /tmp/tmpxft_00004acb_00000000-6_cuda_neoscrypt.compute_30.ptx, line 21682; error : Instruction 'shf.r' requires .target sm_3 2 or higher

ptxas fatal : Ptx assembly aborted due to errors
make[2]: *** [neoscrypt/cuda_neoscrypt.o] Error 255
make[2]: *** Waiting for unfinished jobs....
The fix for 8.13 and older versions is very simple:
Remove in the last line in makefile.am this part:
-gencode=arch=compute_30,code=sm_30
After this fix, the latest 8.13 code compiles fine and is working good under ubuntu Linux
Please consider to remove neoscrypt for SM 3.0

I haven't tested it by myself but have received some issue with this miner.
https://bitcointalk.org/index.php?topic=472510.msg17156655#msg17156655
Seems like "-r 0" option is not working.
Server try to disconnect when algo switch is needed (Sends FIN and close write stream)
but I don't think this ccminer version detects and close.
Can you fix this issue?
fix hashes_done and return second nonce
Hi again. :)
Found another coin that can't be mined.
But this time it should work with ccminer as tpruvot's version works (=finds blocks).

Hello.
noticed that you are working on jackpotcoin now.probably that is an interesting coin but i can't find any info about mining pool or exchange.
can you give me some links, please?=)
thanks
I managed to build the windows branch on Ubuntu (by adding compat/Makefile and copying bitcredit over from an old repo) but the resulting ccminer crashes on my 1070s.
In fact Makefile.am line 81&82
nvcc_ARCH = -gencode=arch=compute_61,code=sm_61
nvcc_ARCH = -gencode=arch=compute_52,code=sm_52
It seems that it should be
nvcc_ARCH = -gencode=arch=compute_61,code=sm_61
nvcc_ARCH += -gencode=arch=compute_52,code=sm_52
And the build works after this change.
There's an "unknown error" or something similar when you try to mine bitcoin.
I can't find the bug.
Yeah, I know. Nobody is mining Bitcoin with ccminer, but I want to fix the bug anyway.
Hello.can you increase hashing speed on neoscrypt for 1080ti like tpruvot does?(1.3-1.4 KH)
i have mixed config with 1070 and 1080ti and can't use his miner cause it works badly with 1070 cards.
thanks.
UPD.sorry, saw that your miner gives that hashrate too on zpools bench. how can i achieve this hashrate with my 1080ti? intensity or something?
your miner shows me only 740 Kh on 1080ti

Whats causing this error?
I am trying to run the neoscrypt algorithm with the latest source compiled version on Ubuntu 16.04 64 bit with CUDA 8.0 and nvidia 381 driver. I keep getting segfaults. Other algorithms seem to run fine. I got the same issue in tpruvot version of the ccminer. What else information is needed to narrow down the bug?

Hello...
./cuda_vector.h(1375): warning: function "__shfl(unsigned int, int, int)" /usr/local/cuda/include/sm_30_intrinsics.hpp(167): here was declared deprecated ("__shfl() is deprecated in favor of __shfl_sync() and may be removed in a future release (Use -Wno-deprecated-declarations to suppress this warning).")
I got this warnings in an endless loop. For the upcomming cuda9 final i suggest, to modify the code to the actual cuda9 definitions. Just to make sure, that in future versions no depracted functions are in use.
Hey, found strange bug.
I have few 1070nvidia rigs. All running win10 with MPM autoswitch script against same pool.
On machines with 1 and 2 cards your ccminer always working good.
On machines with 3 and 7 cards sometimes it do nothing after start, like after "starting 3 threads" no errors, just do nothing. Not always, but pretty often.
As it works fine with all the same env. for 1-2 threads, I expect something related with amount of threads. Only difference that rigs with 1-2 cards is usual home computers with decent amount of ram and ok processors, and 3+ cards rigs is dedicated machines with 4gb ram and celeron 3930 processors. I cant provide any logs, as problem leave no traces. Any ideas? Used 8.06 and 8.08
i have nvidia 12 gpu when i run it's throw this error, if i remove 4 card and run ccminer at 8 gpu it's ok.
please fix it
sytem : ubuntu 16.04 , nvidia 375.66 , cuda8
though i see the lastest version of CCminer have switched to CUDA 8.0
When i try to run mining:

hi, I found out that there is a problem using latest 8.11 ccminer in neoscrypt on several p2pool nodes (ASUS GTX 950). This is what happens:
CUDA ERROR IN FUNC 'NEOSCRYPT_CPU_HASH_K4_2STREAM' AT LINE 1460 : UNKNOWN ERROR
and another issue, this latest version does not support client.reconnect. Will it be available in the future?

Hi
I'm running miningpoolhub.
Some miners asked issue when using your KalusT miner
Seems like other ccminer doesn't produce similar error. Do you have any idea why it happens?
How long is the job refresh timeout interval? Pool sends job within every 55 seconds like most nomp pools.
Only max 1 share will be found in each hash round.
Things are worse with higher throughput and low difficulty
The program uses more and more system memory when running neoscrypt algo until crash.
Debian 9 (Sid) kernel 4.9.0-3-amd64
checking for SSL_library_init in -lssl... no
configure: error: OpenSSL library required
libssl-dev installed
There is hashrate bug in quark. NiceHash shows ~40% less hashrate.
Hello fellow developers,
I am having issue with running ccminer with bitcoin-qt.exe (Solo mining)
I am receiving error below upon start:
[2017-01-26 14:23:57] 1 miner thread started, using 'bitcoin' algorithm
[2017-01-26 14:23:57] Binding thread 0 to cpu 0 (mask 1)

[2017-01-26 14:23:57] json_rpc_call failed, retry after 5 seconds
my ccminer running parameters:
ccminer -a bitcoin -o http://127.0.0.1:8332 -u USER -p 123456789 -R 5 -D
my bitcoin.conf file:
rpcuser=USER
rpcpassword=123456789
server=1
daemon=1
rpcallowip=127.0.0.1
my bitcoin-qt.exe running parameters:
"C:\Program Files\Bitcoin\bitcoin-qt.exe" -server
I thought, maybe bitcoin-qt.exe does not accepting any connections, but when I run bfgminer with parameters:
bfgminer -S opencl:auto -o http://127.0.0.1:8332 -u USER -p 123456789 2>logfile.txt
everything works fine...
P.S. everything is up to date:
Bitcoin v0.13.2 (64 bit)
ccminer v8.05-KlausT
pthreads static 2, 9, 1, 0
libcurl/7.50.3 WinSSL WinIDN
Thanks in advance
When running across many datacenters, getting issues with 15 degree Celsius differences. Would be best if the card could auto-throttle intensity, if you can't access card directly just auto-tune ccminer please so it will restart until it finds best velocity.
THANKS!
