[QUOTE="Eric Sosman, post: 4214993"]
"My blushes, Watson."  (And don't be too awed by my expertise;
the only reason I'm in the top ten of this group -- on good days --
is that the top twenty have stopped posting.)

He didn't say anything about parallel execution at first, which
is why I gave a rather different response on the initial go-around.
But later he wrote that "On the GPU I am using, threads execute
simultaneously [provided...]," and I understood that as a request for
a C construct that expresses the "provided" and guarantees parallel
execution.  C has conditional constructs that may (*may*) involve no
branches, given smooth seas and a following wind, but has nothing that
can guarantee or even talk about parallel execution, leaving aside
signals and volatiles.

'course, it's possible I've misunderstood the O.P. or blundered
in some other way, and will be summarily drummed out of the top ten.
Again.  (Anybody recall the Brain Trust of the TV series "Scrubs?"
Them's my guys ...)
