/// The goal of the summary view is to give a very quick overview of the
/// performance throughput. Below is an example of summary view:
///
///
/// Iterations: 300
/// Instructions: 900
/// Total Cycles: 610
/// Dispatch Width: 2
/// IPC: 1.48
///
///
/// The summary view collects a few performance numbers. The two main
/// performance indicators are 'Total Cycles' and IPC (Instructions Per Cycle).
