Hi, Actually, even I get the same error as Amina but while running in se mode when I use --fast-forward option. The command line I am using is:
./build/ALPHA_MESI_CMP_directory/gem5.opt configs/example/se_modular.py -n 16 --cpu-type=detailed --clock=1GHz --topology=MeshDirSolo --caches --cacheline_size=128 --l2cache --num-l2caches=16 --l1d_size=16kB --l1i_size=16kB --l2_size=128kB --l1d_assoc=2 --l1i_assoc=2 --l2_assoc=2 --num-dirs=1 --mesh-rows=4 --ruby --garnet-network=fixed --rootdir="spec2k" --benchmark="gcc;mgrid;gcc;mgrid;gcc;mgrid;gcc;mgrid;gcc;mgrid;gcc;mgrid;gcc;mgrid;gcc;mgrid" -I 40000000 -F 10000000 I get the error: panic: RubyPort::M5Port::recvAtomic() not implemented! Is this because cpu switching happens from atomic to detailed in case of fast forwarding or checkpointing and ruby does not support atomic accesses? If this is correct, is there any workaround for this? I need to use fast forwarding in my simulations. Please throw some light on this.
