I don't know how I missed that. You ARE maxing out one cpu core, so
you're quite right that you need more threads unless you can make your
single worker more efficient.
Why not just spawn more copies of your program and have them work on
ranges of the data, though? Might that not be simpler than juggling
threading schemes?
