Webcub::BLOCK_STORE_WARP_TRANSPOSE_TIMESLICED. A blocked arrangement is locally transposed into a warp-striped arrangement which is then written to memory. To reduce the shared memory requireent, only one warp's worth of shared memory is provisioned and is subsequently time-sliced among warps. More...

If I understood correctly, you want to reduce Object1.lower.x to one result, Object1.lower.y to another result and so on. For any given object there are four arrays to be reduced, all of equal length (for the object). There are many possible approaches to this, one influencing factor would be the total number of objects in your system. rayovac cr123a battery
