SynRGen: An Extensible File Reference Generator

Date: May 12, 1994

Abstract: SynRGen, a synthetic file reference generator operating at the system call level, is capable of modeling a wide variety of usage environments. It achieves realism through trace-inspired micromodels and flexibility by combining these micromodels stochastically. A micromodel is a parameterized piece of code that captures the distinctive signature of an application. We have used SynRGen extensively for stress testing the Coda File System. We have also performed a controlled experiment that demonstrates SynRGen's ability to closely emulate real users -- within 20% of many key system variables. In this talk, I will present the rationale, design overview, and evaluation of SynRGen.
