[gem5-users] ruby_network_test Memory address range for system.physmem is overlapping

[Tanvir Mustofa via gem5-users]

Hello everyone,

I tried the line suggested in http://www.m5sim.org/Ruby_Network_Test

./build/ALPHA_Network_test/gem5.debug
configs/example/ruby_network_test.py --num-cpus=16 --num-dirs=16
--topology=Mesh --mesh-rows=4 --sim-cycles=1000
--injectionrate=0.01 --synthetic=0 --fixed-pkts --maxpackets=1
--garnet-network=fixed

I am constantly getting this error

Global frequency set at 1000000000 ticks per second

    1.250000 rounded to 1

 I tried with this  ./build/ALPHA_Network_test/gem5.debug
configs/example/ruby_network_test.py and it is giving exactly the same
error just with less warning.


Then I tried ./build/ALPHA_Network_test/gem5.fast
configs/example/ruby_random_test.py --num-cpus=16 --num-dirs=16
--topology=Mesh
--mesh-rows=4 --sim-cycles=1000 --injectionrate=0.01 --synthetic=0
--fixed-pkts --maxpackets=1 --garnet-network=fixed

It gives me the following error

warn: rounding error > tolerance
    1.250000 rounded to 1
warn: rounding error > tolerance
    1.250000 rounded to 1
.
.

Again I tried with  ./build/ALPHA_Network_test/gem5.fast
configs/example/ruby_random_test.py
it gives same error with less warning.

I tried with ALPHA_Network_test/gem5.fast,
ALPHA_Network_test/gem5.debug and ALPHA_Network_test/gem5.opt. I tried
with binaries build with
RUBY=True and without it.

Then I tried with X86_MESI_Two_Level. The errors still persist (both
ruby_network_test and ruby_random_test). Can anyone help me out here.

Thanks in advance.

Regards

Dhruvo
