A simulation run continues until eitherthe specified number of requests is generated or the maximumsimulation time (see below) is reached.PARAM System call/return with each request	I	1 TEST RANGE(i,0,1)INIT synthio_syscalls = i;This specifies whether or not each request occurs within the context of asystem call (which may affect the behavior of the associated processin the system-level model).  If true~(1), each request will bepreceded by a system call event and followed by a system call returnevent.PARAM Think time from call to request		D	1 TEST d >= 0.0INIT synthio_syscall_time = d;This specifies the think time (i.e., computation time) between the systemcall event and the disk request event.
