Hi Da,
You can look at some of the other scripts in my github for examples of how
to fast forward with KVM.
I suggest that you *not* use fs.py since you know what you want to do. You
should write a script like my runkvm.py that runs gem5 exactly how you
need. fs/se.py were originally created as
Hi Jason,
Thanks a lot! Your scripts work!
I am able to scale up to 40 cores on a compute node with 20 physical cores
/ 40 logical cores with your scripts. So I think the fs.py doesn't do
multithreaded mode correctly for running with kvm cpu. Some of your code
are commented as "required" for
Hi Da,
You likely need to enable gem5's multithreaded mode to get many CPUs to
boot correctly. I've had success with up to 32 cores on a 4-core 8-thread
system. I'm not sure if fs.py automatically does this correctly or not. See
my scripts here:
Hey Jason,
The package works.
However, I encountered performance issues with increased CPU number. The
performance was very great with up to 4 CPUs ("-n", I am assuming "number
of CPUs" equal to "number of cores" for testing multithreading workload
later). However, the system fails to boot (or
Hi Jason
The package works (I used the second one)! And it also works with the
package you provided (
https://gem5-review.googlesource.com/c/public/gem5/+/7301) in my another
email to fix the keyboard and mouse issue for running later linux kernel
and ubuntu. (However, there are some conflicts in
These patches "fix" the problem. However, they may not apply cleanly to
HEAD and they definitely are not cleanly implemented.
