Hi everyone,
I recently returned to gem5 and tried to create SimPoints for SPEC and other workloads on ARM
architecture.
gem5 works great as usual, but I am curious why it takes 10~30 mins to write just a single
checkpoint. 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?
If I am understanding what you're saying, the saving of the checkpoint
data is actually quick. it running through the whole OS boot procedure
that takes the 20 minutes +/- ...
