Hello！I‘m a college student and I need to do some work with garnet.
But I found a inexplicable problem recently.
Command to Run:
./build/NULL/gem5.opt
configs/example/garnet_synth_traffic.py \
--network=garnet \
--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 run the above command with gem5-v21.2.1.0+ubuntu20.04.
But,I get different simulation results on different computers with the same
configuration(gem5-v21.2.1.0+ubuntu20.04).
I just changed the computer...
Different computers' random number libraries may act differently.
Also, random number generator packages are usually set up to give
a different random number sequence on each run, unless you
specifically use them otherwise (by giving the same "seed" each
time).
