Hi Alian,
Thanks for your help, so do you mean I should rebuild the gem5 in ARM mode?

Hi-
There is no Ethernet support for the x86 ISA in the vanilla release of gem5.
You should use ARM ISA for multi node simulation.
Best,

Hi,I am currently using dist-gem5 to simulate the cluster environment.
Here is my launch script:
GEM5_DIR=$(pwd)/$(dirname $0)/../../..
IMG=BigDataBench-gem5.img
VMLINUX=vmlinux-22-22-64
#DTB=$M5_PATH/binaries/vexpress.aarch64.20140821.dtb
FS_CONFIG=$GEM5_DIR/configs/example/fs.py
SW_CONFIG=$GEM5_DIR/configs/dist/sw.py
GEM5_EXE=$GEM5_DIR/build/X86/gem5.opt
BOOT_SCRIPT=$GEM5_DIR/util/dist/test/simple_bootscript.rcS
GEM5_DIST_SH=$GEM5_DIR/util/dist/gem5-dist.sh
DEBUG_FLAGS="--debug-flags=DistEthernet"
#CHKPT_RESTORE="-r1"
NNODES=2
$GEM5_DIST_SH -n $NNODES \
-x $GEM5_EXE \

-f $FS_CONFIG \

--ethernet-linkspeed=10Gbps

$CHKPT_RESTORE
After the script is executed, the switch is fine, but the two nodes share the
same error:

I really have no idea how to deal with it. I have search the internet, but
still no clue...
Thanks.
