Thanks a lot! Very useful advice!! I have already turned to the newest gem5 
version and several benchmarks(437,444,470 etc.) begin to work now.
Still some benchmarks return errors, including 410,453,459,464,471,473,482 
Have you worked out any of these?
I got several errors like"cannot open file XXX", even after I specified the 
file path in Mybench.py. How to solve this?

I posted Mybench.py and error messages below.

Best Regards,
Jiakun LI
