Trace-driven systems modeling

摘要

Predicting the effect of changes made to computer operating systems is an extremely difficult task. Where possible, to a limited extent, some modeling has been done; however, because of its complexity, this modeling has been isolated to areas of very high cost or high priority real-time systems.

Trace-driven modeling is a procedure for alleviating both the high cost and difficulty of simulating changes made to computer system environments. As a result, this approach could make computer systems models an everyday tool well within the reach of the average operation.

This paper describes the attributes of the trace portion of this modeling approach and how its output might be used to drive various system models.
