Generating Bitcoins with your video card (OpenCL/CUDA)

Can't wait to see this in action!

I didn't realize that the Mac dmg was already posted to a different thread.

http://heliacal.net/~solar/bitcoin/Bitcoin-MacOSX-Intel-svn-75-opencl-2010-05-10.dmg

Looks like it is a little outdated.

Any chance of the opencl code being patched to the current SVN version?

I can't patch it to the current as I have no way of testing it. Though, if I can determine how to disassemble his I might be able to get a leg up on working off the SVN and making a new one.

Thanks for the link StinkiePhish!  I installed it on my Macbook Pro (GeForce GT 330M), and it runs/connects.
It says "Generating", but I suspect it's not.  The graphics card is still on the Intel integrated chip.

I forced it over to the NVidia, but it still just says "Generating", with no khash/s readout.
Activity Monitor shows Bitcoin using 400% of the CPU, so I suspect nothing is going on the GPU.

Anyone else?

Run

Code:

tail -f ~/Library/Application\ Support/Bitcoin/debug.log

You'll see if its using your card as an extra thread, will also show it initializing the OpenCL program.

I tried the version posted and I was wondering if there would be the possibility to do generation only with the GPU (0 CPU threads and 1 GPU thread).

If the code would be checked-in somewhere, I'd be happy to check out and make other tweaks.

Happy to try experimental code.

Excellent info, Limb!  It seems the OpenCL doesn't automatically 'kick in' the NVidia graphics core. It stays on Intel.  I'm not sure how the OS auto-switches, but whatever it's looking for, bitcoin doesn't trip it.

When Intel is selected, the relevant portion seems to be:

Code:

GetAvailableDevices():  Found 1 OpenCL platform(s)
ThreadOpenConnections started
ThreadMessageHandler started
GetAvailableDevices():  Checking OpenCL platform 'Apple' (index 0)
proxy connecting 
proxy connected 
GetAvailableDevices():  Found 0 devices on platform 'Apple' (index 0)
4 processors

When I force the NVidia, we have ignition!

Code:

GetAvailableDevices():  Found 1 devices on platform 'Apple' (index 0)
Printing info for device index 0  Vendor: NVIDIA  Device: GeForce GT 330M
...
Device 'GeForce GT 330M (NVIDIA)' : CL_KERNEL_WORK_GROUP_SIZE : 192
Device successfully initialized!  (GeForce GT 330M (NVIDIA))

It runs one bitminer thread on OpenCL, and three on the CPU.

Code:

**Perf - thread 1 : 1128k iter/sec
**Perf - thread 2 : 296k iter/sec
**Perf - thread 3 : 293k iter/sec
**Perf - thread 4 : 296k iter/sec
**Perf - total : 2013k iter/sec (4 threads)

I've never seen the MBP fan this excited.

[laszlo]

Yea, I tried that too, after seeing it at 90C temps for a while I decided to not generate with my MBP

It's great that it's working for you - I'm not sure if it's possible to ask the OS to switch to the high performance video automatically, as far as I know you have to go to the power settings and tweak it manually, like you did.

The cooling fans are working hard on my 13 MBP

OSX 10.6.4 - NVIDIA GeForce 9400M

**Perf - thread 1 : 519k iter/sec
**Perf - thread 2 : 317k iter/sec
**Perf - thread 3 : 315k iter/sec
**Perf - total : 1151k iter/sec (3 threads)

Running the original bitcoin I was getting around 6-800k iter/sec

OpenCL bitcoin crashes with a Bus Error on a 27" iMac (ATI Radeon).

Anyone get it to work on a current-gen iMac?

I would very much like OpenCL/Cuda code to generate bitcoins with my GPU:

I'm interested, I'd be twice as interested in the source code though.

I have Windows Vista 64 and an ATI Radeon HD 4830

Also, I have a working 0.3.2 Gentoo Linux version which I compiled from source. I have ATI Stream SDK installed so I have a fully working OpenCL developer kit, the only thing I'm lacking is some sources to add in OpenCL support.

I'd be happy to work on the Linux version.

[em3rgentOrdr]

Anyone know when this OpenCL/CUDA code will be released?  Are there any development versions of this OpenCL/CUDA source code out yet?

[knightmb]

As far as I can tell, nothing else has been done. Seems to only work on a few select Mac at the moment and even then appears to be a little unstable.
