Hi Anirudh,
If you just specify --dual on the command line you'll get two systems and you don't need to actually bother with modifying the regression test you mention below, however you need to think about how they'll connect together. We have PCIe based ethernet network interface models, however that seems like it might not be the right thing for android. If you want to go down the PCIe route, then you'll need to do some work to enable PCIe in VExpress_EMM. Depending on what you want to do, you might want to create a wifi like adapter.

I have been working off twosys-tsunami-simple-atomic.py because that's the only networked benchmark available within GEM5 at present. Can anyone help me out with modifying twosys-tsunami-simple-atomic.py to simulate two ARM devices instead of two ALPHA devices (like it does now). Thanks in advance for any advice you may have in this regard. >> Anirudh, you'll have to take the plunge on your own. Go ahead and modify the python script. At first, it might appear hard to do. But once you start modifying it, the script would not create much problems for you. I think Python has very good debugging support. So figuring out errors is also not an issue. In case you do face difficulties, you can always ask questions on gem5-users mailing list. > > Thank you for your prompt response.
