Web2.1 CUDA Core 按照每个线程计算矩阵C中的一个元素来构建naive kernel，首先确定当前线程处理矩阵C的元素坐标，再遍历K并直接从global memory中加载所需A、B矩阵元素到寄存器参与计算，最后将计算结果从寄存器直接写回矩阵C。 WebIn the figure below, there are three blocks: block 1, block 2, and block 3, all assigned to an SM. Each of the three blocks is further divided into warps for scheduling purposes. We can calculate the number of warps that reside in an SM for a given block size and a given number of blocks assigned to each SM.
