思路:每个Block负责计算矩阵C中的BM * BN个元素,每个Thread负责计算矩阵C中的TM * TN个元素;使用Shared Memory来存放线程间可以复用的矩阵A和矩阵B的元素,一个Block的所有线程每次一起从Global Memory中load BM * BK个矩阵A的元素和BK * BN个矩阵B的元素,存放到Shared Memory中,之后每个线程再分别从Shared Memo...
最后再说一下分块乘法(block multiplication):对于运算AB,可以将A和B分别分成多块,这些块的大小可不相等如[1]: [A1A2A3A4][B1B2B3B4]=[A1B1+A2B3A1B2+A2B4A3B1+A4B3A3B2+A4B
tiled matrix multiplication 上述的并行化算法每个线程独立读取global memory的数据,独立计算对应的输出,没有充分利用数据的局部性和共享内存,比如index为(i,j)的thread,和index为(i + 1,j)的thread,需要读取的A的数据相差一行,需要读取的B的数据完全一样,那我们有没有可能让这两个线程在同一个block中,各自读一...
