Is this better than GUIminer?

I think so.

The miner check the result of the opencl kernel by doing the double sha calculation with the nonce just found by the kernel.

Makes sense.
Thank you.

Hello fellow miners.

I use poclbm without any major problems, but every now and then I will get an error message:

Code:

Verification failed, check hardware! (, <32bit hex value>)

The general advice is to check one's hardware and I concur, but I want to look at it from a different angle.

My question is on the mathematical side. What exactly is tested to perform this verification?
I haven't seen it described anywhere.

A possible workarround for people that have hardware error with the driver 13.4 and can't downgrade the driver ... :

The BFI_INT optimisation look like to be problematic on that driver version, more informations :

https://bitcointalk.org/index.php?topic=221041.new#new

EDIT : i think it should be a good idea to define or not BFI_INT depending on the version of the driver also and not just only the plateform name (aka Jupiter for my 5770)

At least one server is required

That's the important error message, you didn't provide any mining pool server address.

Tried that before, is not working unfortunatelly ...

Code:

sudo fglrxinfo

gives me this

Code:

display: :0 screen: 0
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: ATI Radeon HD 5800 Series
OpenGL version string: 4.2.12217 Compatibility Profile Context 12.104

so I assume a

Code:

export DISPLAY=:0.0

is required? Or do I need

Code:

export DISPLAY=:0

?

Neither ist working ...

Here is everything in one piece:

Code:

xxx@Eibe:/opt/poclbm$ export DISPLAY=:0
xxx@Eibe:/opt/poclbm$ sudo python poclbm.py

WARNING: no adl3 module found (github.com/mjmvisser/adl3), temperature control is disabled

Hey,

i switched from Windows to Ubuntu 12.04 and don't get poclbm running.

I installed ATI Drivers, 12.104 Catalyst as well as SDK 2.8, pyopencl is also running perfectly. But I don't get poclbm working.

The Error reaccurring all the time trying to run

Code:

sudo python poclbm.py http://xxxxxxxx:[email protected]:8332 -d0 -v -w128

The terminal always says

Code:

07/05/2013 12:28:18, Ignored invalid server entry: http://xxxxxxxx:[email protected]:8332

WARNING: no adl3 module found (github.com/mjmvisser/adl3), temperature control is disabled

At least one server is required

Sounds like you need to allocate the correct DISPLAY(s) (the ones associated with your GPU(s) ) to the Xserver ... it's been so long i forget how to do it ... something like

Code:

export DISPLAY = 0.Y

... where Y is number associated with your GPU

I'd like a Windows build as well.

I use my own front-end:
https://bitcointalksearch.org/topic/crypto-miners-in-tray-a-lightweight-front-end-for-unattended-mining-149442
http://stanislavs.org/bitcoin-miners-in-tray-miner-gui-manager/
, but I am forced to have GUIMiner for the sake of the bundled poclbm build, which supports HD 7970.

poclbm_py2exe_20120920.7z linked to in the opening comment gives the following error:

09.04.2013 20:54:27 [AMD HD7970]: Traceback (most recent call last):

The build, included with GUIMiner does not give any errors with the same parameters. I saw on github there were a few bugfix commits.

Can we have the latest and greatest build for Windows, please?

I get the same errors...
I second this, and would love to have an updated standalone package...at least if there is I can't find it

Yes, I still maintain the miner. It is now modular, i.e. you can implement your own hardware or work-source types. I just haven't released a py2exe recently (since BFL support actually) - POCLBM doesn't look so popular anymore and works fine for anyone able to setup python + pip and pull sources from github.

I know a few people that run poclbm in the background on windows mostly just to feel they are supporting an alternative to fiat. They don't follow the scene at all though. I just let them know when I see an update to the windows build to let them know to update. We have been figuring that any worthwhile updates would get check pointed by a build. Is this not really true? Have windows build updates ceased then?

Look like the setup.py isn't really installable

running 'python setup.py install' install only poclbm.py and not other py files, so it can't start.

Did you need help to create a correct setup for linux ? or you care only of windows py2exe release ?

Hi guys, I've been at this all day and I'm struggling to get poclbm to work. Is fglrx really the issue or is it something else? Any help would be greatly appreciated.
