Hi

I've recently purchased a new MacBook Pro 13' which only has the on die Intel Sandy Bridge graphics (Intel 3000 I believe). BOINC does not detect this GPU, according to the messages generated on loading it.

Am I to infer that BOINC is not using my GPU? If not, how can I make it do so?

Thanks
Josh

No, BOINC isn't using it. Not for calculations at least.
How to get BOINC to detect it? Pressure Intel into releasing an API (application programming interface) with which the BOINC developers can do so, preferably one for all normal platforms.

Now, this isn't to say no project could use it. Any project doing OpenCL application should practically be able to address the HD GPU in the processor, just by telling the science application what to look for. But alas, there's no project with Sandy Bridge compatible applications available either.

And even then, I don't know what your experience is with all that onboard embedded stuff, but in my experience it isn't that much good anyway. Nowhere near as powerful as nor as unobtrusive as external cards (with their own loads and loads of memory). And a hell to replace when broke.

I understand its not objectively powerful, but I have been impressed by its ability. I thought the Sandy Bridge integrated GPU would be a valuable resource for BOINC. Given it will ship on many notebooks and desktops, replacing other integrated Nvidia and AMD chips. Even operating in tandem with a graphics card it could be a power supplement for BOINC.

It's a shame intel won't releasing an API.

I didn't say they wouldn't. It's just not here yet, only in the rumour mill. And for OpenCL only at that. Then you still require projects that use it, which there are so far none, with none having plans --last that I read.
