To test this module on your machine, you probably want to avoid overflooding memory. The simplest way is to use the shell's limit (csh, tcsh) or ulimit (sh, bash, ksh) command. This command allows to set a number of limits for the processes launched by the current shell (i.e. only the window you are typing commands in, it does not affect other shell sessions). The syntax of the parameters you can change depends on your shell and platform, but the one reserved for memory usage is usually called datasize.
