Hourglass

Real-time application to learn how CPU scheduling works
This is a port of hourglass, a synthetic real-time application that can be used to learn how CPU scheduling in a general-purpose operating system works at microsecond and millisecond granularities.
-
It creates very detailed map of when each Hourglass thread has access to the CPU
-
It supports multiple thread execution models; e.g. periodic and CPU-bound
-
It acts as an abstraction layer for threading, timing, and CPU scheduling functionality on Unix- and Win32-based systems
