If you look into se.py there should be a some python code that allows you to specify multiple applications on one benchmark. I believe the semicolon is parsed out of the string specifying the workloads and will allow you to load multiple benchmarks per CPU.
If that file hasn't been tweaked too much, you should be able to do something like: gem5.opt ... --cmd="hello;hello" --detailed ... and that would give you two hello world binaries on the O3CPU in SE mode. (But I would say the most important thing is to go through that se.py file and make sure you on a high level understand what's going on. Part of the "goodness" of gem5 is the ability to config through the Python front end..)
