you have no idea what youre talking about
to illustrate it:
take a guess what language this code is from?
float tmpSum = 0;

if (ROW < N && COL < N) {
// each thread computes one element of the block sub-matrix
for (int i = 0; i < N; i++) {
tmpSum += A[ROW * N + i] * B[i * N + COL];
}
}
C[ROW * N + COL] = tmpSum;
