1.gem5 version is v21.2.1.0
2.build command is ??scons build/NULL/gem5.opt -j 4"
3.run command is below and the "--injection-rate" is increasing with step=0.02
Command to Run:
./build/NULL/gem5.opt
configs/example/garnet_synth_traffic.py \
--network=garnet2.0 \
--num-cpus=64 \
--num-dirs=64 \
--topology=Mesh_XY \
--mesh-rows=8 \
--sim-cycles=10000 \
--inj-vnet=0 \
--injectionrate=0.02 \
--synthetic=uniform_random
I find some interesting phenomenons.
I think I figured out where the problem might be.
It might be the permission error and the build order.
I built "X86","ARM","NULL" on my old computer before,so I try to restore it all.
Then I find the miss folder "__pycache__" come out,I think I'm going to get
close to the root of the problem.
But I failed.
I rebuild a same version gem5 on my new computer with the command"??scons
build/Garnet_standalone/gem5.opt -j 4" under the root state.
Then I run the same script,I get the correct output.(I can see the
average_packet_latency is increasing with the --injectionrate)
Although I get the desired output, I can't figure out why I get the wrong
output.

Not sure to understand what you mean by ??correct result".
Can you please provide us with:
gem5 version (commit SHA)
build command
run command
Can you please also double-check that you are using supported versions of
python and gcc/clang. Also check that config.ini is the same in all cases.
