Hi,
I am trying to run a multi core systems in m5-2.0b3 using
O3CPU. I am using an EIO trace of
spec cpu benchmarks. But when I look at the generated m5stats.txt
file, it shows the differenet
number of simulated instructions than that of which i given in
cofiguration file.
Configuration I am using is:
system.cpu[0].workload = [Benchmarks.SPECTWOLFEIO()]
system.cpu[0].max_insts_all_threads = 100000000
system.cpu[1].workload = [ Benchmarks.SPECCRAFTYEIO()]
system.cpu[1].max_insts_all_threads = 100000000
system.cpu[2].workload = [Benchmarks.SPECPARSEREIO()]
system.cpu[2].max_insts_all_threads = 100000000
system.cpu[3].workload = [Benchmarks.SPECPERLBMKEIO()]
system.cpu[3].max_insts_all_threads = 100000000
system.cpu[4].workload = [Benchmarks.SPECGAPEIO()]
system.cpu[4].max_insts_all_threads = 100000000
system.cpu[5].workload = [Benchmarks.SPECVORTEXEIO()]
system.cpu[5].max_insts_all_threads = 100000000
system.cpu[6].workload = [Benchmarks.SPECBZIP2EIO()]
system.cpu[6].max_insts_all_threads = 100000000
system.cpu[7].workload = [Benchmarks.SPECEONEIO()]
system.cpu[7].max_insts_all_threads = 100000000
The result obtained is:
sim_freq
1000000000000 # Frequency of simulated ticks

Can you please suggest how to make each CPU execute the 100000000
instructions?
The max_insts_all_threads parameter only works when a single CPU has
multiple threads (e.g. a SMT out-of-order CPU). If you want to run
separate CPUs until each cpu has reached 100000000, I believe Korey
Sewell sent a couple of patches to the list to do just that in the
last few days.
