| Summary: | (distributed) discrete event simulation (PDES) refers to the (presently) is inherently sequential. The main objective of approach and optimistic mechanisms, like the Time Warp approaches use a detection and recovery approach wherein based upon prediction techniques which performs very well for categories : conservative mechanisms, like the Chandy-Misra causality errors are detected and a rollback mechanism is control commands which are essentially onboard computer deterministic systems. executed on the spacecraft to avoid the catastrophic effects execution of a single discrete event simulation program on a in sequence checking in a spacecraft's control commands. invoked to recover. We present a technique for PDES that is mechanism. Conservative approaches strictly avoid the of incorrect execution. The sequence checking employed parallel computer. PDES mechanisms broadly fall into two possibility of a causality error occurring whereas optimistic programs. 'The sequence of control commands needs to be Spacecrafts are controlled by sequences of time-tagged The motivation for this research has been its applicability this work is to replace this existing sequential algorithm verified for correct execution before the commands are with a parallel implementation to gain performance.
