Which metrics can you collect from my multicore platform?

It is possible to collect a range of metrics by instrumenting your source code with the Rapita Verification Suite (RVS), including a range of execution time metrics:

• RapiTime: high-water mark and maximum execution times
• RapiTask: scheduling metrics such as periodicity, separation, fragmentation and core migration

It is also possible to collect information on events in your hardware using hardware event monitors. The information we can collect depends on the performance monitoring unit(s) (or equivalent) of your system, but typically includes events such as L2 cache accesses, bus accesses, memory accesses and instructions executed. We can also collect information about operating system activity such as task switching and interrupt handling via event tracing or hooks.
