Hi all, I am using the latest version of gem5-stable. I want to restore a checkpoint with ruby and detailed cores. To take and restore the checkpoint I’ve used MESI_Two_Level protocol. I get the following error when a checkpoint is restored.
fatal: Fatal Error:: No Route exists from this Router. @ tick 2475249334500 [routeCompute:build/ALPHA/mem/ruby/network/garnet/fixed-pipeline/RoutingUnit_d.cc, line 85] This is my command line for restoring the checkpoint: build/ALPHA/gem5.fast configs/example/fs.py --ruby -r 1 --cpu-clock=2.5GHz --cpu-type=detailed --restore-with-cpu=detailed --caches --l2cache --num-l2caches=64 --l1i_size=32kB --l1d_size=32kB --l2_size=8MB --num-dirs=64 --num-cpus=64 --topology=Mesh --mesh-rows=8 --garnet-network=fixed --script=configs/boot/fft_64c.rcS For testing purpose, I used the command above with only 4 cores for which the simulation runs OK. I wonder why it's not working for 64 cores. I've also tried /garnet-network=flexible/ but the simulation fails. Does anybody know how to fix this error? Thanks, Shervin
