Configuration File

The configuration file specifies the following: the machine where the master process runs, the port number that the master process is listening at, the total number of client processes, the total number of server machines, and the specification of the server processes for each server machine. The specification of the server processes includes the name of the server machine, the base port number, and the number of ports at which there are server processes listening. For example, if the specification is "cowb06.cs.wisc.edu 8000 10", it means that there is a server process listening at each of the ports 8000, 8001, 8002, ..., 8009 on cowb06.cs.wisc.edu. This way one server machine can host more than one server processes. The inherent hit ratio is an optional parameter as well as $\alpha$ and k, the parameters that define the heavy tail file size distribution. It is also possible to specify the average file size instead of $\alpha$. In this case, $\alpha$ can be calculated by the formula 2.3. The default minimum file size is 3.0KB.
