There is another recent post about bamboo flooring. Coincidentally, I'm also thinking of installing bamboo, Toast from Home Depot.
The subflooring is mostly particle board, 5/8", laid on top of a black fabric on top of a wood floor (not sure how thick). It's not glued down.
There is a big curve in the floor, due to the old building settling. I would estimate a 3" rise over 4-5' distance.
I would lay the flooring in the direction perpendicular to the curve, in other words, the planks would look like a bridge across the gap.
What is recommended for a situation like this? Should the floor be glued down, or should it be floating?
If your floor has a 3" dip in 4'-5' you need to take the floor down to the joist and fix it. If you install any wood floor over partical board (PB) it will have to be a floating installation. You can not nail a wood floor over PB. Nails do not hold. You can not glue wood over PB. The moisture in the glue will make the PB swell and will eventually work your floor loose. I would get rid of the partical board.
