Tiled matrix multiplication with CUDA, the algorithm is from https://www.coursera.org/course/hetero
#define TILE_WIDTH 16
// NOTE: Since TILE_WIDTH is a constant, I cannot use the more readable idiom
// ceil(whatever/16.0) for calculating the number of tiles. Instead I use
// (whatever + TILE_WIDTH - 1) / TILE_WIDTH, which is equivalent. Trust me.
// Compute C = A * B
__global__ void matrixMultiplyShared(float *A, float *B, float *C, int numARows,
int numAColumns, int numBRows,
int numBColumns, int numCRows,
