We investigate techniques for hiding memory latency on in-order CPU cores. The same techniques that the compilers employ.

We investigate techniques for hiding memory latency on in-order CPU cores. The same techniques that the compilers employ.
We try to answer two questions related to compiler optimizations: how can you help the compiler do a better job and when does it make sense to do the compiler optimizations manually.
We investigate what are the techniques your compiler employs to make your loop run faster.
