DoD Systems Interact with Their Physical Environment

Abstract

Briefing Chart Satisfying Real-Time Requirements Is Challenging for Upgrading the Blackhawk UH-60 Helicopter. Commonality of DoD Systems. What Causes Delay of Software? Real-Time Requirements of Software Executing on a Multicore Processor Problem: For each process, compute an upper bound on its response time. How Co-Runners Impact Speed of Execution Problem: For each process, compute an upper bound on its response time. Issues: Shared hardware resources impact timing, 103 times slowdown has been observed [Yun15], Current methods cannot deal with undocumented resources, Even when resources are documented, current methods can only analyze/manage a small set of them. The problem is getting worse: Slowdown increasing, More undocumented h/w.
