Well my copy of Snow Leopard is just about here. I am curious to see if CUDA will:
1. Work out-of-the-box with SETI
2. We will need to install the new Nvidia Driver for Snow Leopard (cudadriver_2.3.1_macos.pkg)
3. (worst option) we will need to wait for an update to the SETI app for mac for GPU crunching (OpenCL version)
I am hoping for 1 or 2, but 3 may be the reality. Anyone know?

As far as I know, there is no app for OSX Cuda yet.

Was afraid of that. So at the most the gain will be from the OS if any.

Don't blame BOINC or the projects. The problem is that nvidea has not yet released CUDA drivers for OSX.

I installed NVidia CUDA 2.3.1 for Mac Leopard on My iMac (spring 2009) with no Co-proccessoers found. Maybe a restart will get it, but now expecting much.

After restart still the same.
Can't load library libcudart
No coprocessors

While it's possible from a programming perspective, CUDA has not been implemented for the Mac version of the Seti BOINC app yet. I don't think there are any apps under BOINC that support OpenCL or CUDA yet.
-Edit- I mean the Mac versions. Lots of CUDA love on the Windows side.

Yep. Hopefully someone with knowledge can get this going. BOINC may be at issue also as it can not see the co-pocessors yet. So there is something missing for it to hook in there. That makes me wonder if it's the projects of the BOINC client that is the issue. Could be both. It almost looks like we will need to see version SETI 6.08 for Mac to get CUDA and then it would likely not have Alex's SSE optimization so someone would need to do that too it. Makes me wonder if I can muster enough brain cells to jump into XCode with it.

Well reading more CUDA may be hot, but also too hot for some GPUs. Since only MacPros have removable video cards it may not be something one would want to do to their GPU. At least unless you can throttle it in the software (run xx% of the time like with CPUs). Also, I see you can't run both SETI CPU and GPU at the same time. May be OK if you run one BOINC project CPU and another GPU. BOINC is working on that though.

You can run both if you are running the optimized apps from Lunatics, but I am a ATI person so run SETI on my CPU's and Milkyway/Collatz on my GPU's.
