Paul Church	Title Eventrons: High-Frequency Hard Real-Time Tasks in Java Abstract In my previous CGL tech talk, I presented the "Metronome" real-time garbage collector from IBM Research. Although Metronome has been very successful and achieved pause times around 1ms, the idea of real-time garbage collection has limits and is not suited for high-frequency tasks with deadlines in the sub-millisecond range. The existing fallback approach has been the highly modified memory model of the Real-Time Specification for Java (RTSJ), which allows for threads that can preempt the garbage collector. However, RTSJ has very serious drawbacks. This paper, presented at PLDI 06 by a CMU prof and some IBM researchers, introduces a different construct that allows high-frequency threads to be independent of the GC in a safer and less complicated way.
