With OSB it doesn't really matter. Usually one uses plywood, it is superior in
every respect and it matters because you want the grain running perpendicular
to the joists for maximum strength. Some of that OSB is also 49 by 97 inches
which is a pain in the proverbial.
Some OSB has a waxed side though, if yours does you want it up to help shed any
moisture.
Really though, plywood is superior and you can buy it for flooring with tongue
& groove edges. 5/8ths is thick enough on 16 inch centers and a bunch lighter
to haul up those stairs

Does it matter which way you lay down OSB board on the floor joists?
Does the long edge have to run parallel to the joists, or doesn't it
matter? I laid out the joists with the idea that the short edges would
run parallel to the joists, but before I start screwing things down, I
want to make sure I don't screw them up.
