ok, I'm really new at this GPGPU stuff, I got this message when I try to run the thing:

Traceback (most recent call last):
  File "poclbm.py", line 28, in
   miner = cl.Program(context, kernelFile.read()).build()
  File "/usr/lib/pymodules/python2.6/pyopencl/__init__.py", line 138, in program_build
   "Build on %s:\n\n%s" % (dev, log) for dev, log in build_logs))
pyopencl.RuntimeError: clBuildProgram failed: build program failure

Build on :

Error: Code selection failed to select: 0x138fdc0: i32 = bswap 0x138fbc0

-------------------
This is on Linux 64 bit, does the "i32 = bswap" mean it wants linux 32?

btw I know the 8400 GS is slow, you don't have to tell me.

Got the same error on a Win7-64 with 8600 GTS.

Code:

Build on :

Error: Code selection failed to select: 0x5d57918: i32 = bswap 0x5d57808

Seems like poclbm doesn't work on nvidia cards.

Well .. 256mb .. DDR2 with 64 bit interface
this even was crap when it came on the market ^^

I think I have the newest stuff. Ill just have to wait for the next version by the looks of it. Maybe give up on it and find an ATI card.

Try to update your GPU driver. See http://forums.nvidia.com/index.php?showtopic=150585

It seems OpenCL is still problematic on Nvidia GPUs. Unfortunately I don't have one to try to make a PyCuda miner.

I can't get the getwork patch to compile into bitcoin. Is that something satoshi has considered adding to the main trunk?

I've got PyOpenCL finally installed but without the patch in the client, I can't request anything.

try :

svn co -r 161 https://bitcoin.svn.sourceforge.net/svnroot/bitcoin

It seems any other revision fails the patch.

It only tries to keep single kernel run under specific time by changing the number of 'global' threads. If you start a game, kernel execution will get slower. The number of threads will then be gradually adjusted to achieve the desired execution time.

By default this time is 1/60 of a second. If shorter i.e. 1/120 sec it will leave more time for other GPU tasks.

This is adjusted with the '-f' switch.

It think fixed point is relatively good to ati and hard for nvidia.

That sounds interesting. Do you have any web-sources for this ?

@m0mchil:
Is your Python OpenCL client using priorization ? like, can I start a game while using your client and it will automatically slow down the hash rate and my card will focus on the game ?

of course, but still
i'd like to know if that's a usual expectation on ati cards compared to nvidia,
no single-hd5870-users around that want to share their hash-count?

i'm gonna buy a new card sooner or later anyway and i don't mind if it says ati or nvidia on it,
both will surely run my game/s.
but if one of them is x times better crunching blocks and besides that, prolly cheaper too,
i already know what my next favourite brand is.

gflops is not really relevant to bitcoin mining since gflops is measure of floating point and bitcoin mining is fixed point. It think fixed point is relatively good to ati and hard for nvidia.

If you have an app that uses floating point more than fixed point the the disparity might vanish or at least diminish.

Right after these lines is there something like:

ProcessBlock: ACCEPTED
sending: inv (37 bytes)

If so (and you are sure this is the block in question) it was announced to the network, but another block got included in the chain instead. Do you have other blocks after that?

BTW, if you want poclbm to crunch slower, start it with something like -f 400. Experiment with the number.

Here's one for you.

It just found another block, and... bitcoin doesn't show anything...

The miner asks for work at an interval of 10 seconds. If there is a new block from the network in the last such interval your client won't even try to announce your own next block. I am not sure, but I think this is the behavior of the original client too. Please take a look at your debug.log and if possible send me an excerpt from around where this happened. Look for terms like "SetBestChain" and "height=" if you know the block number.

Sometimes the client just doesn't show the new transaction right away.

Yes, I am.

Uhm, does anyone know if poclbm works with mutliple graphic cards ?

More people need to jump on board of the OpenCL miner.

Anyone fancy building a 64bit windows build of bitcoin suitable for the OpenCL miner? It may be worth some bitcoins Wink

yes 4870, edited my post.
and yes, more people should use it

now I can generate bitcoins on my gpu and rainbow tables on my cpu at the same time Tongue

I copied them into system32, this usually sloves these problems, but I'm gonna try it.

PS: the German error message only says, that the module was not found.

EDIT: and again, you were right Cheesy

but now a new error message shows up:

Code:

C:\Program Files (x86)\Bitcoin>python poclbm.py
Unable to communicate with bitcoin RPC

I'm using this client:

Win32 bitcoin with getwork, against SVN 161. Download

EDIT2: ok forget it, forgot about the -server switch
EDIT3: yay it works, finally.
BUT, now it asks for username and passwords every ~8 seconds.... ?

EDIT4: I changed the default values for user and pw in pocbm.py and now it works

hey, it's me .. again ...

python poclbm.py -->

Code:

Traceback (most recent call last):

Seems like a DLL is missing.

wtf ?
when I click that link I get forwarded to http://developer.amd.com/Pages/amd404.aspx

edit: works with IE O.o but not with firefox, hmm.
maybe I changed my http referrer settings or something.

while trying to install pyopencl 0.92 with "python setup.py install" I get the following error:

using Python 2.6.6, setuptools 0.6c11, NumPy 1.5.0, SciPy 0.8.0, Boost 1.44

any recommendation ?

Smoketoomuch, get version 2.6.6 AND get the 32 bit binaries.

If you install the 64 bit, the extensions are all based on 32 bit, and it won't find your installation. Reinstall with 32 bit and you're golden.

oh ok, thanks, now it works.
all I need is a stream sdk for 64 bit now -.- cmon AMD! fix it!
