Korey,
Thanks a lot! I've patched the program by using the patch you posted.
Now the program is running very well on SimpleCPU. But when I change the CPU
model to O3CPU there also seems only one workload has been run.
system = System(cpu = [DerivO3CPU(cpu_id=0,clock="1GHz"),
DerivO3CPU(cpu_id=1,clock="2GHz")],
physmem = PhysicalMemory(range=AddrRange("512MB")),
membus = Bus(), mem_mode = 'timing')
Can you further check the code? I'm using M5 2.0b5 now.* *Thanks.
Jerry
