Configuring RSIM

 

This chapter discusses the various run-time and compile-time options available to configure RSIM, and specifies the default values for the parameters. The parameters most frequently modified in our experience are available to the user on the RSIM command line; most other parameters are presented to RSIM via a configuration file. Many configuration files can be used for different simulation runs, as the name of the configuration file is passed to RSIM on the command line. Many of the parameters ask for time in processor cycles; this is the main metric used in RSIM. By default, we assume a processor with 300 MHz and choose some of the default latencies with this in mind.
