说明：  反向阵列（multiblock）: 给定指针d_a中的输入数组{a0，a1，...，an-1}，将反向数组{an-1，an-2，...，a0}存储在指针d_b中 A: 从“reverseArray_multiblock”模板开始 B:多个256线程块启动,要颠倒大小为N，N / 256块的数组 第1部分：计算要启动的块数 第2部分：实现内核reverseArrayBlock 请注意，现在您必须同时进行计算 块内的相反位置 反向偏移到块的开始
(Reverse array (multiblock): Given the pointer d_a in the input array {a0, A1,..., an-1}, the reverse array {an-1, An-2,..., a0} stored in the pointer d_b A: starts with the "reverseArray_multiblock" template B: more than 256 thread block start, to reverse the size of N, N / 256 block array The first part: the number of calculation to start The second part: implementation of kernel reverseArrayBlock Attention, now you must calculate at the same time The reverse position in a block Reverse offset to block start)
