This command sets the random number seed for a master random number generator. This generator is used by SPARTA to initialize auxiliary random number generators, which in turn are used for all operations in the code requiring random numbers. This means you can effectively run a statistically-independent simulation by simply changing this single seed.
The various random number generators used in SPARTA are portable, which means they produce the same random number streams on any machine.
This command is required to perform a SPARTA simulation.
