I am on my phone and thus cannot easily look at the line that failed at the moment, but my first step would be to increase the size of the memory gem5 is assuming — try —mem-size=8GB or 16GB and let us know if that solves the problem. Matt Sent from my iPhone On Mar 10, 2022, at 5:12 PM,

[gem5-users] gem5 + multicore CPU example

Hi, Is there an example system python code like apu_se.py that puts together a multicore CPU (quad or oct) and creates the interconnect with approximate latency between those cores ? If yes, where to find this example model ? Thanks, David ___

Thank you so much. There were some questions that you missed at the end of the email. I list them below again for convenience: - Is there a better way you can suggest using SPEC2017 in FS mode to evaluate my system on gem5? - My understanding is that the FS simulation is significantly

Hi Abdelrahman, >From the get error message, it says: "This error may be caused by a too restrictive setting in the file '/proc/sys/kernel/perf_event_paranoid' The default value was changed to 2 in kernel 4.6 A value greater than 1 prevents gem5 from making the syscall to perf_event_open"
