Hi Brian,
I am working on a similar experiment and I just made a little progress
today. The command I used are as follows:
{
$ scons build/ALPHA_MOESI_hammer/gem5.opt
$ build/ALPHA_MOESI_hammer/gem5.opt -d m5out/null
--stats-file=stats.cpuc-16.txt configs/example/ruby_fs.py -n 16
--cpu-type=timing --topology=Mesh --mesh-rows=4 --num-dirs=16
--num-l2caches=16 --script=configs/boot/null.rcS
}
It runs and exits successfully if the rcS doesn't take checkpoint, but as
soon as I set the rcS to take checkpoint it fails. You can try it and let
me know.
I also try to followed isca_pres_2011.pdf too but it didn't work for me
either. I believe it is outdated. Now I am almost shooting in darkness. Can
anyone kindly point us to an updated ruby memory system guidebook for
beginners or somewhere to get started?
Thanks!
Yuchen
