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.

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.
