[ANN] [QRK] Quark | Core 0.10 upgrade

[quarkcoin]

Thanks to Neisklar for releasing a version of CPU miner for Quark.

Announcement thread:
http://forum.quarkcoin.org/Thread-ANN-poolers-cpuminer-with-quarkcoin-support

Source code here:
http://www.share-online.biz/download.php?id=CU5H5NRMJK

The win executables took some time to compile, they are linkes in the announcement thread, and here:
Win64: http://www.share-online.biz/download.php?id=E7OXBNRMUU
Win32: http://www.share-online.biz/download.php?id=L78K8NRMGUG

Since the quark-algo is pure plain c, i compiled it for different processor/instructionsets, just pick one that works best for you. AVX better than SSE and so on. Win64 will definatly gain heavy speed improvements: On my old core2 laptop, I had a win32_sse3 run with around 9-12 khash/s per core. With w64_sse4 i got around 22-26 khash/s per core.

Is it faster? Github?

Yes definatly, one core on wallet: ~11kHash/s, w64_sse4 one core: ~23kHash/s
So at least on my testing machine and win64: around 100% gain

Github will come hopefully after the weekend, and hopefully coreectly setup as fork.

https://github.com/uncle-bob

for nearly a 30% improvement in hash rate

Yeah nice, taking it out of the loop, need to try out whats the speedgain in the cpuminer.
I wonder if we get even more gain (since memory is not an issue) if we create for multiple times used hash functions in one hash run, distinct contexts, and then combine them in one big struct, so thats one big continous block of memory which can be copied with one single memcpy call, instead now 9 calls for smaller blocks.

When getting rid of my old quark wallet and installing this new one, do i do it like with the scrypt coins. Like get the wallet.dat  and back it up, delete everything else then install the new quark wallet?

Also any step by step guide to setting this new cpu miner up on ubuntu 64bit?

No, this is not a new qt wallet, only a standalone miner that mines more efficiently than the miner built into the qt wallet. You keep your current qt wallet application and wallet.dat file the same.

See this thread for using the miner on the p2pool:

It's basically:

Code:

minerd_xyz.exe [b]-a quark[/b] -t <numthreads> -o http://176.221.46.81:8372 [b]-u <youquarkaddress>[/b]

This pool takes cucrrently 3% fee, which you can verify yourself:
http://176.221.46.81:8372/fee

Please also inform you about how p2pool works, esp about that fake difficulty:

Putting the hash_init-stuff outside of the loop isn't gaining anthing in cpuminer

You grab the sources, and compile it yourself

You'll need the package needed to build, like autoconf, automake, gcc, libcurl. (Depending on your linux OS, everything you need is packed into "build-essential" or "base-devel" ).

Good morning,

just let me add this thread, first post:

https://bitcointalk.org/index.php?topic=55038.0

There are detailed instructions for different systems, ready for copy & paste. Just modify the steps for the source download.
GitHub Repo will hopefully be on shortly

[eule]

eule@Debian-70-wheezy-64-LAMP:~/cpuminer-2.3.2-quarkcoin-src-dist$ ./autogen.sh
bash: ./autogen.sh: Permission denied
eule@Debian-70-wheezy-64-LAMP:~/cpuminer-2.3.2-quarkcoin-src-dist$ ./configure CFLAGS="-O3"
bash: ./configure: No such file or directory

Can't execute autogen.sh even as root. Since there's no configure file i guess autogen must be run first.  

Amazing work btw.

Hopefully i didn't make any mistakes:

Thanks.

For your autogen problem: A quick google search turned this up:

Code:

chmod a+x autogen.sh

Hopefully thats the solution

[eule]

Thanks, that command helped indeed. Also tried your git, got this error after make:

Code:

minerd-cpu-miner.o: In function `miner_thread':
/home/eule/quarkcoin-cpuminer/cpu-miner.c:786: undefined reference to `scanhash_quark'
collect2: error: ld returned 1 exit status
make[2]: *** [minerd] Error 1
make[2]: Leaving directory `/home/eule/quarkcoin-cpuminer'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/eule/quarkcoin-cpuminer'
make: *** [all] Error 2

But the sourcecode i downloaded earlier compiles fine, getting around 50 kHash per core on an i7 930.

same problem here
git version wont compile

[eule]

Download from the link he posted earlier.
Virtual server gets 258 kH/s with the wallet, 288 kH/s with the new miner.

Sorry, had the updated Makefile forgotten, please update your local repos. Thanks


Edit: Repo will be temporaly unaccessible and will afterwards need a new clone. Sorry
Edit2: Repo now again accessable, please delete you old local repo and clone a fresh one. (Now i better should read a git tutorial)

Another day of mining QRK? 

[spoid]

i'm a bit blind - are there 64 bit executables for the uncle-bob-wallet yet?

[cryptohunter]

diff highest today for a while, faster mining with cpu miner or more miners getting involved?

Also can someone confirm to back up quarks all you need to do is make a copy of the wallet.dat like with the scrypt coins? Some people are saying that is not sufficient with this coin?

Can the cpuminer be used to solo mine?  I will try some on the pool and some solo to compare.

good questions that need an answer
giving a bump

wallet.dat is sufficient.

yes it should work, just point it at your wallet's rpc port, e.g. http://127.0.0.1:8811/ instead of at the pool.

Personally i think the higher diff is also due to faster mining software, and hopefully more interest with all the new stuff in the last days

Edit: to slow, but i leave it

Yes backing up your wallet.dat should be sufficent enough. Basically only the private key (from which a single address is then computed) is all that matters. If you have that private key, you can spend that money. You can also dump all private keys, print them to a sheet of paper, and put it in a safe place. (Note that new created addresses after the backup are not included).
I currently have the idea greatly inspired by amory to create a coin independent private key generator with deterministic behavior like amory.
That means you just have to secure one single (than longer) key somewhere on paper in a safe place, and ALL your privated keys you generate with that tool are safe, as they can always be regenerated by that one master-backup.

Of course you can solo mine. Thats what i did a while to test the minerd code.
You need to enable your wallet (quarkcoin-qt) to act as a "rpc-server"

Edit your quarkcoin.conf file, located (Win) %APPDATA%\Quarkcoin, or (Linux) ~/.quarkcoin
And add/modify the following entries:
(of course you can change user/pass and port the way you like)

Code:

server=1
rpcuser=rpcuser
rpcpassword=rpcpass
rpcallowip=127.0.0.1
rpcport=8910

Then you can use the minerd like (out of the mind, not tested):

Code:

minerd.exe -a quark -o localhost:8910 -u rpcuser -p rpcpass

If you have multiple machines, you don't need the wallet on every computer. Just add additional lines with rpcallowip and point the remote miners to the IP the wallet is on.

@neisklar, is the p2pool source @ github? want to run one localy

[K1773R]

What the heck... I can't get it to compile. I have all the needed requirements like gcc, build, etc.

When I go to do make or anything else, all I get is error. Tried this on the github and source code .zip
 
How do I get this to work? 

autoconf, libcurl4-openssl-dev missing

[eule]

chmod a+x autogen.sh
./autogen.sh

Do these two things first (has been posted above  ).

Same errors...

azure@yourofl:~/cpuminer-2.3.2-quarkcoin-src-dist/cpuminer-2.3.2-quarkcoin-src-dist$

That is from the .zip source, not github. I have everything installed (autoconf, libcurl4-openssl-dev) etc. 

well, there is a README file, are you unable to read?
