Hi Tushar,
Thanks for answering this. I tried your command
"./build/ALPHA_MESI_CMP_directory/gem5.opt
configs/example/ruby_random_test.py --num-cpus=16 --num-dirs=16
--topology=Mesh --mesh-rows=4 --garnet-network=fixed -l 1000", however
problem still exists.
Error message is:
Error: could not create topology Mesh
Traceback (most recent call last):
File "<string>", line 1, in <module>
File
"/home/xchen19/gem5_new/gem5-stable-f75ee4849c40/src/python/m5/main.py",

AssertionError
looks like still the old problem.
Thanks,

Hi Xi,
The Network_test coherence protocol and ruby_network_test.py work in
tandem, and is for simulating synthetic network-only traffic.
With other coherence protocols (such as MESI_CMP_directory) as you are
using currently, you should use other testers (such as
ruby_random_test.py), or run in full-system mode.
./build/ALPHA_MESI_CMP_directory/gem5.opt configs/example/ruby_random_test.py
--num-cpus=16 --num-dirs=16 --topology=Mesh --mesh-rows=4
--garnet-network=fixed -l 1000
The "-l" option in the ruby random test specifies the number of cycles for
which injection should occur. This tester injects synthetic reads and
writes into ruby.
cheers,
Tushar
