The brittleness of tests or specs is a recurring topic in BDD (or acceptance test-driven development, specification-by-example, or whatever you choose to call the thing where you write acceptance criteria, automate them and then make the application match). This is a tricky area, and there are probably as many styles of defining and grouping acceptance…
The most critical intervention point to affect design at and across all physical scales (see graphic below) is to pay attention to the processes and patterns underlying their physical manifestations…
Hardware performance monitoring counters have recently received a lot of attention. They have been used by diverse communities to understand and improve the quality of computing systems: for example, architects use them to extract application characteristics and propose new hardware mechanisms; compiler writers study how generated code behaves on particular hardware; software developers identify critical regions of their applications and evaluate design choices to select the best performing implementation. In this paper, we propose that counters be used by all categories of users, in particular non-experts, and we advocate that a few simple metrics derived from these counters are relevant and useful. For example, a low IPC (number of executed instructions per cycle) indicates that the hardware is not performing at its best; a high cache miss ratio can suggest several causes, such as conflicts between processes in a multicore environment. We also introduce a new simple and flexible user-level tool that collects these data on Linux platforms, and we illustrate its practical benefits through several use cases.
