committedInstructions are the number of machine instructions that have been committed. The number of ops is greater than or equal than the number of instructions. If an instruction is executed without being cracked its an op, if it is cracked then everything it's cracked into are ops. sim_ops and sim_insts is a count of all ops instructions that the simulator has executed (on all CPUs and isn't reset when the statistics are). It's meant for analyzing the performance of the simulator.
