I have a shiny new Mac Pro and am chasing some bugs in parallel
applications that may have to do with things like cache flushing,
memory barriers and OSAtomic<whatever>. I recall from somewhere, I
think, that there is an mechanism somewhere, selectively to disable
processor cores (or perhaps entire processors, in the case of the Mac
Pro). Such a mechanism would be very useful for my tests.
If there is a Cocoa interface to this mechanism, perhaps someone could
tell me what it is?
If there is a non-Cocoa interface, perhaps someone could advise me off-
line?
I am a little hampered in searching the usual references in that I do
not quite know what keywords to use.
Thanks very much ...
