Abstract
Simulated computer hardware is differentiated from physical computer hardware for user code by detecting a sequence of instructions which produce no effect on physical computer hardware but which set a flag on simulated computer hardware. User code may thus issue the sequence of instructions, then check the flag to determine whether it is executing on simulated hardware or physical hardware.
