Is it possible for a block of threads to discover which processor its running on?
My reason for asking is that it appears that on some GPU the clocks diverge and
re-initialising the GPU does not re-sync them. I think this happens on C2050
but does not appear to be a big problem on either (some) earlier or
(some) later GPUs.
I have a feeling this has come up before, but I could not find the answer.
All help, advice and comments are most welcome
