So, is there anything in this much-hyped technology that is actually a
benefit to audio developers, to enable them to do what has not been done
before (like, use all "available" cores for audio processing)?
If not, it is another nail in the coffin of the general-purpose computer
as an audio processor, and the industry will move even further towards
custom hardware in which they can implement whatever parallel processing
they need, and have full control over it.
Also, presumably an older d/c iMac with the Radeon1600 chipset cannot
run openCL code, so can it at least degrade gracefully to at least build
and run on such a machine?
On an 8-core Mac Pro, how many cores will we see Logic Pro using?
This all rather reinforces speculations I have made that in the headlong
rush to concurrent multi-core nirvana, audio will be left behind, or
simply ignored/underestimated as a relevant activity.

Ehm, you know that GCD is running at the main thread level? Which can be
blocked by UI operations, etc. That doesn't seem like a wise choice for
real-time processing. OpenCL also doesn't have a threading mode, so you
tasks will be shared among all the others and your latency becomes
unpredictable.
