simulation time concurrency using continuations… • simulation time Thread • cooperative concurrency • can also support pre-emptive, but not necessary • simulation time concurrency primitives: • CSP Channel: JistAPI.createChannel() • locks, semaphores, barriers, monitors, FIFOs, … JiST – Java in Simulation Time 26
ewriter flexibility • simulation time transformation • extend Java object model with entities • extend Java execution model with events • language-based simulation kernel • extensions to the model • timeless objects: pass-by-reference to avoid copy, saves memory • reflection: scripting, simulation configuration, tracing • tight event coupling: cross-layer optimization, debugging • proxy entities: interface-based entity definition • blocking events: call and callback, CPS transformation, standard applications • simulation time concurrency: Threads, Channels and other synch. primitives • distribution: location independence of entities, single system image abstraction • parallelism: concurrent and speculative execution • orthogonal additions, transformations and optimizations • platform for simulation research • e.g. reverse computations in optimistic simulation [Carothers ’99] • e.g. stack-less process oriented simulation [Booth ’97] JiST – Java in Simulation Time 27
