Abstract :
TIME is a powerful set of tools that can be used to investigate many issues involving I/O and its relationship to process scheduling and the memory system. The tools include a translation (TLB) simulator, virtual-to-real address translation via page tables, main memory allocation, process scheduling for a multiprogramming environment, and a disk system simulator. TIME is trace driven. Traces are obtained from instrumented applications. To study the interaction between the system architecture and the I/O system, the traces must contain memory references and application I/O requests. The tools combine statistical access properties with the simulation of timed events. The result is an execution profile showing the I/O activity for a workload
