Hi,
Thank you Ali, I could run it after passing --at-instruction.
I have another question, please. I'm using my own python code version,
and it doesn't have checkpointing and restoring from checkpoint options.
So, inside the code I call m5.checkpoint(dir). The checkpoint output
directory includes 2 files, "system.physmem.store0.pmem" and "m5.cpt".
There is no chekpoint folder like the ones I gave previously by using
se.py file (e.g. cpt.bzip2_source.179600). How can I restore from the
new checkpoints, and where are they (if any)?
Many thanks
Negar

Hi Negar,
When you restore you need to pass --at-instruction so the code that is
restoring from the checkpoint knows that the format should be by
instruction count and not tick count.
Thanks,
Ali

Hi,
I'm trying to create a checkpoint at a specific instruction number
and stop execution, then start running from the checkpoint for 100
number of instructions and then exit. Below are the commands I'm
using. Would anybody tell me if I'm running the correct commands?
Since I got the message "Exiting @ tick 281314000 because a thread
reached the max instruction count" for the first command, which I
guessed should be "... because reached the max number of checkpoints
"! And, an error message for restoring as follows.
Command line to create checkpoint:
/build/ARM/gem5.fast -d system/disks/CPU2000/output/
configs/example/se.py --bench bzip2_source --warmup-insts=1000
-cpu-type=atomic --at-instruction --take-checkpoints=179600
--max-checkpoints=1/
Command line to restore from checkpoint and run for 100 instructions:
/build/ARM/gem5.fast -d system/disks/CPU2000/output/
configs/example/se.py --bench bzip2_source -cpu-type=atomic -r
1////--maxinsts=100/
