We propose the notion of logical reliability for real-time program tasks that interact through periodically updated program variables. We describe a reliability analysis that checks if the given short-term (e.g., single-period) reliability of a program variable update in an implementation is sufficient to meet the logical reliability requirement (of the program variable) in the long run. We then present a notion of design by refinement where a task can be refined by another task that writes to program variables with less logical reliability. The resulting analysis can be combined with an incremental schedulability analysis for interacting real-time tasks proposed earlier for the Hierarchical Timing Language (HTL), a coordination language for distributed real-time systems. We implemented a logical-reliability-enhanced prototype of the compiler and runtime infrastructure for HTL.
