Arm full system simulation issue

[ksungkeun84]

Hi, firstly, thank you very much for sharing your work. I really enjoyed reading your paper so I am trying to run your implementation. However, when I just run your script (run_parsec_from_ckpt.sh), the simulation just finished with following message. The last line looks something wrong. Exiting @ tick 18446744073709551615 because simulate() limit reached

Can you give me advice for solving this issue? Thank you in advance.

Please make sure to use the correct the checkpoints. Some configurations which are used when generating the checkpoint, such as the number of cores, should match the run_from_ckpt script. Also I would like to suggest to test UnsafeBaseline before trying the defense configurations.
