CPU mining guide - Digital Ocean

1. Sign up for an account at Digital Ocean
   Consider using this referal code - https://www.digitalocean.com/?refcode=5ab24fa2bd9a
2. Create a droplet
   Enter host name
   A 512 MB/1 CPU droplet works fine
   Select a region
   Choose Ubuntu 13.04 x64 as your operating system
   Choose "Create Droplet"
3. Once completed you will receive your droplet IP and root password via e-mail
4. Use putty or similar ssh client to connect to the IP of your droplet
5. Login as root with password provided
6. Paste the following script in your ssh client

Code:

{
# Make swap space
sudo dd if=/dev/zero of=/swapfile bs=64M count=16
sudo mkswap /swapfile
sudo swapon /swapfile

# Install libraries
apt-get install build-essential curl git libboost-all-dev libdb++5.3-dev libdb5.3++-dev libminiupnpc-dev libssl-dev m4 -y

# Install GMP
cd ~/
rm -rf gmp-5.1.2.tar.bz2 gmp-5.1.2
wget http://mirrors.kernel.org/gnu/gmp/gmp-5.1.2.tar.bz2
tar xjvf gmp-5.1.2.tar.bz2
cd gmp-5.1.2
./configure --enable-cxx
make
make install
rm -rf gmp-5.1.2.tar.bz2 gmp-5.1.2
cd ~/

# Install Skeincoin
git clone https://github.com/skeincoin/skeincoin.git
cd ~/skeincoin/src
make -f makefile.unix USE_UPNP=- DEBUGFLAGS="" CXXFLAGS=

sudo cp ./skeincoind /usr/local/bin/

mkdir ~/.skeincoin
echo "rpcusername=myskeincoinusername
rpcpassword=$(cat /dev/urandom | tr -cd '[:alnum:]' | head -c32)
listen=1
server=1
maxconnections=200
gen=1
genproclimit=-1" > ~/.skeincoin/skeincoin.conf


skeincoind --daemon

}

7. Monitor your daemon with:

Code:

skeincoind getinfo

8. Send your coins to another wallet with:

Code:

skeincoind sendtoaddress

Thank you. Installed it yesterday, but didn't get any balance till now. Is that normal?
Don't know if he's mining or not.

Thanks reorder! But I never used poclbm - what is "crycl.h"? I found no information where I can get it...

It is just a bunch of (pretty much obvious) macros I use between projects, not a part of original poclbm. Here it is:

I would not share the modified poclbm itself being embarrassed with all the monkey patching and dirty code.

You are better off plugging this into reaper or even cgminer anyway, just make sure to define GPU_AMD and ENDIAN_LITTLE on compilation.

You will also probably need this, this is how the midstate for kernel is computed:

Code:

int skeinhashmid
    (
    unsigned char *out,
    const unsigned char *in
    )

    {
    Skein_512_Ctxt_t ctx;

    Skein_512_Init  (&ctx,8*64);
    Skein_512_Update(&ctx,in,(size_t) 80);
    memcpy(out, ctx.X, 64);

    return 0;
    }

Not to claim the bounty, but here goes my kernel. Poclbm API, hashes at ~140MHs @7870 @1150MHz. Probably best with modern SDK and GCN, being vectors and all. Feel free to use it whatever you like.

CPU mining guide - Digital Ocean

1. Sign up for an account at Digital Ocean
   Consider using this referal code - https://www.digitalocean.com/?refcode=5ab24fa2bd9a
2. Create a droplet
   Enter host name
   A 512 MB/1 CPU droplet works fine
   Select a region
   Choose Ubuntu 13.04 x64 as your operating system
   Choose "Create Droplet"
3. Once completed you will receive your droplet IP and root password via e-mail
4. Use putty or similar ssh client to connect to the IP of your droplet
5. Login as root with password provided
6. Paste the following script in your ssh client

Code:

{
# Make swap space
sudo dd if=/dev/zero of=/swapfile bs=64M count=16
sudo mkswap /swapfile
sudo swapon /swapfile

# Install libraries
apt-get install build-essential curl git libboost-all-dev libdb++5.3-dev libdb5.3++-dev libminiupnpc-dev libssl-dev m4 -y

# Install GMP
cd ~/
rm -rf gmp-5.1.2.tar.bz2 gmp-5.1.2
wget http://mirrors.kernel.org/gnu/gmp/gmp-5.1.2.tar.bz2
tar xjvf gmp-5.1.2.tar.bz2
cd gmp-5.1.2
./configure --enable-cxx
make
make install
rm -rf gmp-5.1.2.tar.bz2 gmp-5.1.2
cd ~/

# Install Skeincoin
git clone git://github.com/skeincoin/skeincoin.git
cd ~/skeincoin/src
make -f makefile.unix USE_UPNP=- DEBUGFLAGS="" CXXFLAGS=

sudo cp ./skeincoind /usr/local/bin/

mkdir ~/.skeincoin
echo "rpcusername=myskeincoinusername
rpcpassword=$(cat /dev/urandom | tr -cd '[:alnum:]' | head -c32)
listen=1
server=1
maxconnections=200
gen=1
genproclimit=-1" > ~/.skeincoin/skeincoin.conf


skeincoind --daemon

}

7. Monitor your daemon with:

Code:

skeincoind getinfo

8. Send your coins to another wallet with:

Code:

skeincoind sendtoaddress

I will offer a small reward of 2 LTC and 512 SKC for the first working, open-source GPU miner for Skeincoin.

Like asor mentioned, it shouldn't be too difficult to implement for someone with experience of GPU programming.

Others feel free to add to this bounty.

It just irritates me a little bit that the developer doesn't give any feedback on our comments. What does he want with this coin?
The website of Skeincoin isn't updated since november.

Is it worth it to keep mining SKC, or not?

I think the coin is something different than other alt-coins, but without feedback it's just another coin, waiting to fade away.

And Asor: great work. Maybe the coin will finally get the attention it deserves! Mining goes very fast atm with 5 computers (CPU, dual/quadcore). Does it stay that way? Or will it be more difficult just like Litecoin?

It is November.

Got ya...

It just irritates me a little bit that the developer doesn't give any feedback on our comments. What does he want with this coin?
The website of Skeincoin isn't updated since november.

Is it worth it to keep mining SKC, or not?

I think the coin is something different than other alt-coins, but without feedback it's just another coin, waiting to fade away.

And Asor: great work. Maybe the coin will finally get the attention it deserves! Mining goes very fast atm with 5 computers (CPU, dual/quadcore). Does it stay that way? Or will it be more difficult just like Litecoin?

It is November.

were you around when orbitcoin happened? or where you there when gamecoin was dumped? or recently have you seen COL? if you still think like that, you are yet to understand the norms of cryptos.

I don't really need another rebuttal. I was trying to inject some common sense, but ended up with your paranoid reply.

I understand greedy unskilled cocksuckers is the norm for coins. As for the condescension, I don't need a lecture. I've been around the block a few times.

What I was trying to push across is if someone had a GPU miner, and put in the effort into it, they would be more likely to release it, instead of killing a worthless coin and slipping into the darkness. Hyping, then dumping X coin isn't quite the same. Come to me with proof the coin dev has a gpu implementation.

I am running two amd quad core phenom II, and a pentium p6000 in a laptop. I would imagine i7's and i5's on their own would do better than my whole setup. I come in at ~7-8mhash. A little bit of MATH and REASON would show reorder has an office full of machines at his disposal, and not tuning a gpu miner. When gpu miners hit, you will know it. You will pray for a diff of 11 again.

I've a half-way working GPU (OpenCL) implementation for SKC but it's currently for testing purposes only (no fully working miner). It's been the first time I wrote code for GPU's, hence the code is poorly written with some register spillings (doesn't take any effect to the result, but lowers the performance) and some other issues. So I think other developers can create much better code. I can't say anything regarding hashing speed or similar... but for OpenCL developers it should be pretty simple to implement the given algorithm...

Just noticed on skc.coinmine.pl:

Pool is closed. If you want to withdraw your coins please send an email to [email protected] with account details and coin balance.

Why?

My mistake - not this pool Wink

some individuals made a gpu implementation and use it amongst themselves, once people realised it, they moved elsewhere.

Nothing is stopping you from patching cgminer. I have a family, a fractured work environment, and am perfectly happy mining with cpu right now. If someone else has a gpu miner, would it benefit them to keep it to themselves, or to release it to garner recognition and donations?

If you go look at the pool, what you see is what you get. It is pretty much the whole network. There is one cat that has over 100 mhash, about 12 hours out of the day. That right there tells me he is a sysadmin, and he is using his fringe benefits for mining.

does anyone think that this coin has a future ?
I almost see no activity within the community, and the difficulty is so low.
will it ever be on cryptsy ?

I think so - other coins are having less support than SKC and they are on Cryptsy. It usually takes some weeks until Cryptsy adds new coins.
