[AMD Official Use Only - General] Hello,
If you want to run CPU+GPU right now you will probably need to use SE mode. Timing CPUs are not supported in GPUFS configs so the CPU network is completely ignored as KVM/atomic bypass network. If that doesn’t matter, then you will need to create a topology with only GPU components. You can use an existing topology and simply remove CPU Ruby components to do this. Then you will need to use the --gpu-topology option to pass it in. -Matt From: Y阿Z阿 via gem5-users <gem5-users@gem5.org> Sent: Tuesday, May 7, 2024 6:47 AM To: gem5-users <gem5-users@gem5.org> Cc: Y阿Z阿 <1765197...@qq.com> Subject: [gem5-users] gem5 cpu-gpu heterogeneous NoC Caution: This message originated from an External Source.

Hello everyone, I am running cpu-gpu heterogeneous NoC in the Gem5 simulator, and this is my command line. bench=blackscholes #!/bin/bash outDir=gem5/m5out/parsec build/VEGA_X86/gem5.opt configs/example/gpufs/runfs.py \ --disk-image image/kernal/x86-gpu-fs-20220512.img \ --kernel image/vmlinux-5.4.0-105-generic \ --gpu-mmio-trace benchmark/gem5-resources/src/gpu-fs/vega_mmio.log \ --script ./Rcs/run_parsec.rcS \ --ruby \ --network=garnet \ --num-cpus=2 \ --num-compute-units=10 \ --num-dirs=16 \ --dgpu-mem-size="16GB" \ --num-l2caches=16 \ --mesh-rows=4 \ --mem-type="DDR4_2400_16x4" \ --mem-channels=2 \ --mem-ranks=2 \ --mem-size="16GB" \ --cpu-topology=Mesh_XY \ --gpu-topology=Mesh_XY During the construction of the mesh architecture, the following bug appeared. NameError: name 'option' is not defined At: /root/gem5/configs/topologies/Mesh_XY.py(53): makeTopology /root/gem5/configs/example/gpufs/DisjointNetwork.py(90): connectCPU /root/gem5/configs/example/gpufs/Disjoint_VIPER.py(176): create /root/gem5/configs/example/gpufs/system/system.py(227): makeGpuFSSystem configs/example/gpufs/runfs.py(211): runGpuFSSystem configs/example/gpufs/runfs.py(282): <module> src/python/m5/main.py(629): main I would like to ask everyone, can cpu-gpu heterogeneous NoC be run in Gem5? If so, what configuration files do I need to change? Thank you very much for your help. ________________________________ [Image removed by sender.] Y阿Z阿 1765197...@qq.com
