Which is better option to use for dividing an integer number by 2?
...ter of the compiler got to choose among several implementation choices, usually with substantial constraints. Here, one constraint is that the % and / operators must be consistent for both positive and negative operands so that (a/b)*b+(a%b)==a is true regardless of the signs of a and b. Usually, th...

Why is there huge performance hit in 2048x2048 versus 2047x2047 array multiplication?
...he misses on matice1 are not the problem because they are accessed sequentially.
However for matice2 if a full column fits in L2 (i.e when you access matice2[0, 0], matice2[1, 0], matice2[2, 0] ... etc, nothing gets evicted) than there is no problem with cache misses with matice2 either.
