I'm trying to launch simulations with more than 256 cores, this is my
simulation parameters and the output:
./build/NULL/gem5.opt configs/example/garnet_synth_traffic.py
--num-cpus=512 --num-dirs=512 --mem-size=8192MB --network=garnet2.0
--topology=Mesh_XY --mesh-rows=1 --sim-cycles=1000
--synthetic=uniform_random --injectionrate=0.01
The output (crash) after initialization and so on:
Traceback (most recent call last):

Looks like something with interleaving address ranges is wrong, I've
followed the wiki to build in Garnet standalone mode and I'm using the
example script with no modifications at all. All I've changed is the
--num-cpus=512, --num-dirs=512 and --mem-size=8192 command line options to
simulate a network of 512 cpus.
Does anyone have any idea about what is going on here? Is there any way to
disable interleaving address ranges?
