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.
