Benchmarking is hard: processors learn to predict branches

Benchmarking is hard: processors learn to predict branches

A lot of software is an intricate of branches (if–then clauses). For performance reasons, modern processors predict the results of these branches. In my previous post, I showed how the bulk of your running time could be due to…

Mispredicted branches can multiply your running times

Mispredicted branches can multiply your running times

Modern processors are superscalar, meaning that they can execute many instructions at once. For example, some processors can retire four or six instructions per cycle. Furthermore, many of these processors can initiate instructions…
