FGBI
v14 v15 73 73 main observations: (1) Their downtime results are very similar for "idle" run. 74 74 This is because Remus is a fast checkpointing mechanism and both LLM and 75 FGBI are based on it. There is rare memory update for \idle" run, so the type75 FGBI are based on it. There is rare memory update for "idle" run, so the type 76 76 II downtime in all three mechanisms is short. (2) When running NPB-EP ap- 77 77 plication, the guest VM memory is updated at high frequency. When saved for 78 the checkpoint, LLM takes much more time to save huge \dirty" data caused78 the checkpoint, LLM takes much more time to save huge "dirty" data caused 79 79 by its low memory transfer frequency. Therefore in this case FGBI achieves a 80 80 much lower downtime than Remus (reduce more than 70%) and LLM (more
