This is our second report on the Sun Java Real-Time System (RTS) experiments. In this report we describe the findings on RTS 2.0 beta release that includes the real-time garbage collector (RTGC). We performed a number of experiments to determine whether the availability of RTGC will result in a better software architecture for the Global Integrated Fire Control System (GIFC)--a component of the C2BMC element of the Ballistic Missile Defense System (BMDS). Our experiment shows that it is possible to use only the Real-Time Java threads that use the heap memory for the GIFC software. SUN RTJ 2.0 gives programmers more control over the priority of the garbage collection. We developed a real-time monitor design pattern to support the implementation of time-constrained computations that use the heap memory, and a methodology to determine the RTS run-time parameters (thread priorities, memory usage, process load, and task deadlines) necessary for the timely execution of these time-constrained computations. Approved for public release; distribution is unlimited. |
