Hi all,
I modified the routing algorithm in the garnet2.0. I used this command
"./build/NULL/gem5.debug configs/example/garnet_synth_traffic.py --num-cpus=64
--num-dirs=64 --network=garnet2.0 --topology=Mesh_XY --mesh-rows=4
--mesh-cols=4 --sim-cycles=10000 --synthetic=uniform_random
--routing-algorithm=2 --vcs-per-vnet=2 --inj-vnet=2 --injectionrate=0.001",
the gem5 ran successfully. However, I used this command "./build/X86/gem5.opt
configs/example/fs.py --cpu-type=timing -n 64 --num-dirs=64 --ruby
--network=garnet2.0 --topology=Mesh_XY --mesh-rows=4 --mesh-cols=4
--routing-algorithm=2 --vcs-per-vnet=2", I got some errors:
panic: Possible Deadlock detected. Aborting!

I want to know the reason and how to solve this problem.
Thanks in advance for any help.
