So, my MacBook Pro (model 5,3) has an nVidia 9600M GT. That should support GPU via cuda, but even after installing both the latest toolkit, and then the latest cuda drivers, I still get "no usable GPU's found" messages in BOINC's startup messages. I added Collatz and Einstein to my projects to try to take advantage of the GPU's, but now they're just sucking up time from my other projects I care more about. Without GPU support, they're going to get the boot from my system. :-(
I even added the cc_config.xml file listed above, but it generates a "no start flag" error message.
My MacPro (3 years old next month), has two graphics card in it, an ATI X1900 and an nVidia GeForce 7300. Too bad neither of those support GPU processing. That nVidia card is just in there sucking up juice. There's no monitors attached to it. Think of all the number crunching goodness an extra dedicated GPU could do 24/7! I'd replace the 7300 with a cuda capable card if I knew for sure it would actually work and these BOINC apps would take advantage of it. Heck, I'd consider replacing the ATI as well. I've got a few spare dollars laying around for a "good cause".
Any suggestions?
