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.
