- The Hartstone Benchmark, Version 1.1
- ====================================
-
- The Hartstone benchmark is a set of timing requirements for testing a
- system's ability to handle hard real-time applications. It is specified
- as a set of processes with well-defined workloads and timing constraints.
- The name Hartstone derives from HArd Real Time and the fact that the work-
- loads are based on the well-known Whetstone benchmark. "Hard" real-time
- applications must meet their deadlines to satisfy system requirements;
- this contrasts with "soft" real-time applications where a statistical
- distribution of response times is acceptable.
-
- Five test series, of increasing complexity, have been proposed for Hart-
- stone and the first of these, the Periodic Harmonic (PH) series, has been
- implemented in the Ada programming language at the Software Engineering
- Institute (SEI). Known as version 1.0 of Hartstone, it has been available
- publicly for the past two years. Version 1.1 of the benchmark is now
- available. This new version corrects some minor errors in the 1.0 release.
- It has also been restructured to enable users to use a debugger as an inter-
- active interface for preliminary tuning of Hartstone parameters and for
- performing multiple Hartstone experiments. This eliminates the need for
- repeated compile-link-download cycles when tuning and running Hartstone.
- It also facilitates experimentation with non-harmonic task sets, i.e. the
- Periodic Non-Harmonic (PH) test series.
