With "blocking algorithm", do you mean that you divide the matrices up in 
blocks to reduce cache misses? For instance, to compute the product of two 
N-by-N matrices, partition them as an (N/n)-by-(N/n) block matrices of 
n-by-n blocks, and multiply the blocks. I had a quick look at the code and 
that does not seem what you're doing ...
