# This is an example script to start a dist gem5 simulations using
# two AArch64 systems. It is also uses the example
# dist gem5 bootscript util/dist/test/simple_bootscript.rcS that will
# run the linux ping command to check if we can see the peer system
# connected via the simulated Ethernet link.
