NUM_PARTS is the number of private histograms (parts) each histogram is split into.
Each warp lane is assigned to a specific part based on the lane ID. However, lanes with the same ID in different warp use the same private histogram. This arrangement helps reduce the degree of conflicts in atomic operations.
