This is weird; it never took me more than 20 seconds to generate a single checkpoint in gem5. I suspect most of the time is spent on draining the system.
Would you be able to debug which draining method is stalling the checkpointing process?

The simulated system has 16 GB DRAM. Typically taking a snapshot of a similar system spends just a couple of minutes if we use VMware, QEMU, or other hypervisors. Is there anyone who dug into this issue? Thanks, Hanhwi IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.
