Hello,
I am working on the same project team as Prannav Shrestha, but I am
experiencing another problem using m5-2.0b5.
When trying to run a single core O3 system in SE mode with two threads on
the core (i.e. two EIO workloads), the simulation runs for an abnormally
long amount of time, though max_insts_all_threads is set very low. For 100
max_insts_all_threads, the simulation ran for over 2 hours before I manually
decided to kill it.
Can anyone help me and tell me if I'm doing something wrong on my end?
Here are the command line options I used:
/space/robertpu/m5-2.0b5/build/ALPHA_SE/m5.opt -d output
/space/robertpu/m5-2.0b5/configs/example/se.py -n 1 -d --caches
Here is the config file (modified se.py):
# Simple test script
#
# "m5 test.py"
import m5
from m5.objects import *
import os, optparse, sys
m5.AddToPath('../common')
import Simulation
from Caches import *

#from cpu2000 import *
import Benchmarks
#End of changes by R. Pulumbarit
# Get paths we might need. It's expected this file is in
m5/configs/example.
config_path = os.path.dirname(os.path.abspath(__file__))
config_root = os.path.dirname(config_path)
m5_root = os.path.dirname(config_root)

parser.add_option("-c", "--cmd",

Any help would be appreciated,
