Am I having a dumb attack? His smarter version ends up multiplying row x row instead of row x column. Doesn't this produce an incorrect result?
The multiply itself is not being changed. Rather, the order in which the elements in the matrices are being multiplied is changed. The results will be the same.
thx for the link appearing last in the article about parallel computing patterns, quite a good wiki.
