Hi Juyoung, In future pls send the emails directly on gem5-users so that others who experienced similar problems can help out as well? I am cc:ing gem5-users
I just pulled out the latest version of gem5 and ran this exact command and it worked fine. Are you getting this error only with ruby and garnet and this particular protocol? It seems to me that it might be some C++ version issue etc … Can you test it with another protocol too, without garnet. Eg: scons build/ALPHA_MOESI_hammer/gem5.debug ./build/ALPHA_MOESI_hammer/gem5.debug configs/example/ruby_random_test.py --num-cpus=4 --num-dirs=4 --topology=Mesh --mesh-rows=2 -l 1000 [The -l command in ruby_random_test specifies the number of cycles to inject]. - Tushar On May 8, 2012, at 1:31 PM, Juyoung Jung wrote: > Hi Tushar, > > > I am trying to run Garnet simulator with gem5 following the documentation > found at http://www.gem5.org/Networktest.
