As high-performance architectures become more intricate and complex, so too do the capabilities to monitor their performance. In particular, hardware sampling mechanisms have extended beyond the traditional scope of code profiling to include performance data relevant to the data address space, hardware topology, and load latency. However, these new mechanisms do not adhere to a common specification and as such, require architecture-specific knowledge and setup to properly function. In addition, the incoming data is often low-level and difficult to attribute to any useful context without a high level of expertise. This has resulted in a destructively steep barrier to entry, both in data acquisition and analysis.

Mitos provides a simple interface for modern hardware sampling mechanisms and the ability to define attributions of low-level samples to intuitive contexts. We present the Mitos API and demonstrate how to use it to create detailed yet understandable visualizations of performance data for analysis.
