You would use one of those approaches:
If you align and pad each slot there won't be any false sharing and the stream prefetcher can kick in if there's only one producer or consumer.
If you use bijective hashing you reduce false sharing without aligning and padding. This can save memory at the expense of the stream prefetcher never kicking in.
