Easy Ubuntu python OpenCL mining setup

[Dusty]

Thank brunopio!
Your hint solved my problem.

While for yours:

Code:

Traceback (most recent call last):
  File "poclbm.py", line 3, in <module>
    import pyopencl as cl
  File "/usr/lib/pymodules/python2.6/pyopencl/__init__.py", line 3, in <module>
    import pyopencl._cl as _cl
ImportError: libOpenCL.so.1: cannot open shared object file: No such file or directory

I found this topic: http://bitcointalk.org/index.php?topic=3359.0;all
but I do not kown what to do next...
=(

Try with:
apt-get install python-pyopencl

[Pander]

in /opt/ati-stream-.../lib/ do

Code:

sudo ln -s libOpenCL.so libOpenCL.so.1

[JWU42]

Bruno's issue is that the LD_LIBRARY_PATH isn't in .bashr

Code:

export LD_LIBRARY_PATH=/opt/ati-stream-sdk-v2.1-lnx64/lib/x86_64/:$LD_LIBRARY_PATH

This assumes your are following Raulo's guide and using 2.1 and are on x86_64

How do I change the PW's after running the script

trying to mine on my HP laptop...xubuntu 32bit, nvidia 8400m gs

seems to be having trouble communicating with bitcoin RPC, can anyone help?

Just cloned the git repo on my Ubuntu 11.04 machine and started the miner without any issues at all.
Thanks for such a smooth piece of software 
Currently reporting ~ 6.3 Mhash/s on my Geforce 8600 GT, very impressive.

One additional question: do the hashes generated by poclbm show up in the "hashespersec" statistic shown by "bitcoind getinfo"? Seems like they don't...

Hi,
I just got through these steps to bitcoin mining on a NVidia GF9400 and I get just 2350khash/sec. That's not so impressive against my low end Core2Duo with 1680khash/sec.

Is my card not so good?

Cheers...

[ethereal]

Aha, got it. Thanks!

Currently mining at ~20,000 khash/s on a AMD 550v; my CPU usage is negligable.

Hello guys i managed to get it working ... i'm currently trying to conect to bitcoin.cz could anyone please tell me the command to do so.

Thank you

[AngelusWebDesign]

Glad it worked for you too! Sure, I'll accept donations at 1JpsaZmgqaPTx9pHayPHxNK3uuHqahDZ12.

Ok, just sent you 10 bitcoins.

This is quaint to read -- I see it came from January of this year.
Today you'd never see someone give 10 BTC, no matter how grateful they were
That would be $90 at today's prices.

Thank you

python poclbm.py -d 0 --user USER --pass PASSWORD --host=mining.bitcoin.cz --port=8332

This miner uses about 50% cpu although it is supposed to be a gpu miner. What could be the cause of this? I guess this isn't the normal behaviour?

Hi everybody,

I have tried to rum poclbm on Ubuntu 11.04 my graphics card is Nvidia is the following (output of lshw)
product: C67 [GeForce 7000M / nForce 610M]

If I run poclbm I get:

$ ./poclbm.py
Traceback (most recent call last):
  File "./poclbm.py", line 27, in <module>
    platforms = cl.get_platforms()
pyopencl.LogicError: clGetPlatformIDs failed: invalid/unknown error code

I have read previous links but that did not help. I have nvdia drivers installed and also CUDA installed.
Thanks in advance.

When I run the last command, I receive
Traceback (most recent call last):
  File "poclbm.py", line 3, in <module>
    import pyopencl as cl
  File "/usr/lib/pymodules/python2.7/pyopencl/__init__.py", line 3, in <module>
    import pyopencl._cl as _cl
ImportError: libboost_python-py27.so.1.42.0: cannot open shared object file: No such file or directory


Libboost_python 1.42 has been installed, so I do not know what the issue is.

Then it's maybe in the wrong place, if it's actually installed?

This miner uses about 50% cpu although it is supposed to be a gpu miner. What could be the cause of this? I guess this isn't the normal behaviour?

now I got:

Yo, first post...I too have this problem trying to get mining up and running.
I'm using an NVIDEA graphics card, so I think the problem is that I'm running a 32-bit machine and the script is assuming is 64-bit. Thing is I'm fairly new to both Ubuntu and Python so I've no idea what to do! Any help would be greatly appreciated.

$ ./poclbm.py
Traceback (most recent call last):
  File "./poclbm.py", line 27, in <module>
    platforms = cl.get_platforms()
pyopencl.LogicError: clGetPlatformIDs failed: invalid/unknown error code

When you have this problem, you should check /etc/OpenCL/vendors/amdocl32.icd - this file should exist and contain the string "libamdocl32.so"
(for a 64-bit system, replace 32 with 64).

I've gone through this installation process, but I seem to be spending most of the time downloading blocks.

Also, is there somewhere that defines what the command line arguments are? Can I use my GPU and both CPU cores?  How can I look in my wallet?

Guys,

 I would like to update this thing a bit, look:

 

Do not use Ubuntu 11.04 with NVidia cards! The poclbm.py/python process will consume all of your CPU for nothing. This behavior does not exist in Ubuntu 10.10.

 

The poclbm in Ubuntu 10.10 does not consume 100% of CPU, but Xorg does if you try to use the mining machine as a daily Desktop...  

 New procedure:

Code:

cd ~

sudo add-apt-repository ppa:stretch/bitcoin
sudo apt-get update
sudo apt-get install python-pyopencl subversion git-core bitcoin

svn checkout http://svn.json-rpc.org/trunk/python-jsonrpc
cd ~/python-jsonrpc/
sudo python setup.py install
cd ~

mkdir ~/.bitcoin
echo "rpcuser=user" > .bitcoin/bitcoin.conf
echo "rpcpassword=password" >> .bitcoin/bitcoin.conf

bitcoin -server &

git clone https://github.com/m0mchil/poclbm.git
cd ~/poclbm
python poclbm.py -d 0 --user user --pass password

 You can change the command:

Code:

bitcoin -server &

 to:

Code:

bitcoind -daemon

 ...if you do not want the GUI interface of Bitcoin client.

 Advantages of this approach:

 1- To upgrade Bitcoin client, just run:

Code:

sudo apt-get update
sudo apt-get upgrade

 2- To upgrade poclbm, just run:

Code:

cd ~/poclbm
git pull

 3- To upgrade python-jsonrpc, run:

Code:

cd ~/python-jsonrpc/
svn up
# If there is a new version:
sudo python setup.py install
cd ~

 That's it!

Cheers!
Thiago

P.S. Ubuntu sucks.
