    // 调用kernel函数，<<<1,1>>>指gpu启动1个线程块，每个线程块中有1个线程
    // <<<256,1>>>指gpu启动256个线程块，每个线程块中有1个线程, 如果是这样，就会有一个问题：
    // 既然GPU将运行核函数的N个副本，那如何在代码中知道当前正在运行的是哪一个线程块？
    // 这个问题可以在代码中找出答案：
    // int tid = blockIdx.x
    // 乍一看，将一个没有定义的变量赋值给了变量tid,但是 blockIdx 是一个内置变量，在cuda运行是中已经定义了。
    // 这个变量把包含的值就是当前执行设备代码的的线程块索引。
    // 
    // 问题又来了，为什么不是写 int  tid = blockIdx呢？ 事实上，这是因为cuda支持二维的线程块数组，对于二维空间的计算问题，
    // 例如矩阵数学运算或者图像处理，使用二维索引往往回答来很大的便利，因为他可以避免将线性索引转换为矩形索引。
