Update : I Oc'ed my 5970 GPU clock from 725 MHZ to 800 MHZ and my memory clock from 1000 to 1305MHZ.
I'm now at 295m on each heart, total of 590m. Everything seem to be fine, I will let you know about futur update and how much I can get with the 5970.

Topic: python OpenCL bitcoin miner - page 51. (Read 1239039 times)
Tried the -f 35 and -w 128. I get around 270m khash/s. And yes, I can load 2 separate poclbm, using device 1 and device 2, both are doing around 268m khash/s. Total of 536m khash/s.
And yes, it display the bitcoin is downloading blocks... Thanks !

From now on I'll post latest versions only in the initial post of this thread.
The miner should display 'bitcoin is downloading blocks...' until all blocks are downloaded. Please test. This was added in the SVN 163 patched client.
David, I removed usage of vectors. So the '-w 128' is not relevant anymore. Of course you can grab the vectors version from git and use it like before. It is really difficult to optimize for all possible devices. Current version is kind of best for all.

I see
Thanks for the info and for the help david, I really appreciate it. If you want me to do some test or help you on something, don't hesitate.

The 4 that you see was just after I finished installing it. It was still downloading block. About the public or the test, I supose i'm on the public network. I simply did the bitcoin -server, and started the poclbm. While I was reading, I heard about a shared pool. Is it really that good ? If you have any info you can help me don't hesitate, I'm open to anything =) Btw i'm on irc ( Malouin ) presently if you wanna talk !

Yes, just took you a screenshot

I'm pretty sure I can get the 500 by using my 2 heart, or maybe i'm totally wrong XD

265 mhps? 
It finally work on my side !
Without optimisation, I got around 265000 khash/sec. I got an i7 920 oc to 3.6ghz with a radeon 5970. I'm gonna look to do some tweak to speed up this thing a bit
If you have any comment or something you want me to try don't hesitate. By the way, I've been running this thing tonight, and in 8 hours, my wallet is still at 0. Is it normal ? Do I need to restart it? Or it's just like the way it should work, which mean it's still pretty long to generate? Thanks for your OpenCL gui Moo, I really appreciate it !
Malouin
P-S I think I only got 265000 khash/sec on my 5970 because i'm only using 1 heart. When I'm at the point I need to choose the device, I see 3 option, 0 = my cpu, and 1 and 2 is the same thing. is it possible ?

Hi,
First, thanks for this wonderful miner.
I managed to make it work on linux (lib64 only) with a 8600 GT
(A bit disappointed about my card performance though: 5300kh/s)
Got this error too, just put some "u"s at the end of all these uint constants. Example:

Any ideas?

hum, you can check with dependency walker (http://www.dependencywalker.com/) that your OpenCL.dll file (in C:\Windows\System32\) provides the OpenCL 1.1 functions needed by pyopencl :
clCreateSubBuffer
clCreateUserEvent
clEnqueueCopyBufferRect
clEnqueueReadBufferRect
clEnqueueWriteBufferRect
clSetUserEventStatus
If not, then either the driver installation has failed, or it is not the good driver.
Otherwise ... I don't know
Edit : you can check with GPU Caps Viewer if this GPU really manage OpenCL, because 2000 kh/s is what is currently made by the CPU alone.
The Geforce 9800 GX2 is if I'm rigth two 8800 GTX functionning in pair, not sure that they manage OpenCL.

tnx, working fine now, forgot the username.
On my other pc i get this error "ImportError: DLL load failed: The specified module could not be found."
I already updated to latest graphics drivers and nvidia cuda toolkit..
Geforce 9800 GX2 @ win7 32 bit
i also noticed that the old puddingpop cuda client only puts out 2000khash/s on that gpu... i should get at least ten times as much...
any ideas?

I'm not sure if and whats going wrong, i started bitcoin in server mode. start poclbm with user and pass, then it shows khash/s for about 5 seconds then pops back to asking username and pass. i can keep doing that over and over.
seems to work now on my GTX260
hashcount results are similar to puddinpops cuda-code,
both get around 45Mhash/s.

poclbm_win32_exe.7z Wrong kernel was packed in the py2exe version, now fixed. Removed AMD OpenCL.dll to prevent conflicts.
I also reverted back to scalars. With vectors it was faster, but required hardware specific tweaks and was making it slower for others. Unfortunately OpenCL is not mature enough to provide means of automatic performance optimization.

Can someone give direct links to NVIDIA OpenCL 1.1 drivers?
I didn't success to found a link to this driver (and I found two cd iso on bittorent, but I don't try to get them) ...But Nvidia has apparently merge his OpenCL implementation in his CUDA Toolkit and drivers. The latest "Developer Drivers" from the "CUDA Toolkit 3.2 RC" page contains an OpenCL 1.1 compliant* driver (it is the one I use).
*at least concerning the openCL 1.1 functions needed by pyopencl
http://developer.nvidia.com/object/cuda_3_2_toolkit_rc.html
Scroll down in the page to found the drivers for windows, linux (some distributions), and MacOS)
Note : GPU Caps Viewer shows me OpenCL 1.0, but it works anyway.
