Hey everyone, For research purposes, I'm trying to run the *PARSEC *benchmark on Garnet 2D mesh topology. I successfully simulated garnet synthetic traffic under standalone protocol, after building gem5 using the following command *scons build/NULL/gem5.opt PROTOCOL=Garnet_standalone -j<proc>* I've used the configuration file for XY routing which is located at */gem5/configs/topologies/Mesh_XY.py* The full command for simulating garnet synthetic traffic is ./build/NULL/gem5.opt ./configs/example/garnet_synth_traffic.py --synthetic=uniform_random --network=garnet --mesh-rows=4 --num-cpus=16 --num-dirs=16 --topology=Mesh_XY--sim-cycles=25000000 --router-latency=4 --link-latency=1 --injectionrate=0.05 The simulation for the garnet synthetic traffic is successful and everything is fine. I've tried to run the PARSEC benchmark so I followed the x86-parsec readme file at gem5 resources repo - https://gem5.googlesource.com/public/gem5-resources/+/refs/heads/stable/src/parsec/ Gem5 is built using the following command: *scons build/X86/gem5.opt -j<proc>* The benchmark is working fine and the simulation is successful. Currently, I want to run the PARSEC benchmark in garnet and run the network on chip in full system simulation. I would really appreciate it if anyone could help me with the steps on how to do it.

Hi Karim, The x86-parsec readme file runs experiment using gem5s new standard library, and it does not support garnet at the moment. Therefore, I had to go with fs.py (which is deprecated in current version of gem5). I was able to replicate the same experiment using fs.py and using the same gem5 resources. I was able to do these steps and run parsec benchmark with garnet in full system mode upto 64 cores. Following are the links and scripts I used, you may need to change them according to your requirement. 1. I used the prebuilt X86 parsec disk image from gem5 resources : https://resources.gem5.org/resources/x86-parsec?version=1.0.0 2. For linux kernel I used vmlinux-4.4.186 3. Example Simulation.py the KVM switch on ROI start can be found here (https://github.com/hansikaweerasena/gem5-n/blob/kvm-fs/configs/common/Simulation.py). 4. Example rcs script can be found here : https://github.com/hansikaweerasena/gem5-n/blob/kvm-fs/scripts/parsec.rcS 5. Finally, following is an example command to run parsec on FS mode with garnet. ./build/X86/gem5.opt configs/example/fs.py --disk-image=dist/parsec.img --kernel=dist/vmlinux-4.4.186 --num-cpus=4 --num-dirs=4 --cpu-type=X86KvmCPU --cpu-clock=2GHz --caches --l1d_size=16kB --l1i_size=16kB --l2cache --num-l2cache=4 --mem-type=SimpleMemory --mem-size=3GB --ruby --network=garnet --topology=Mesh_XY --mesh-rows=2 --script=scripts/parsec.rcS Regards, Hansika Weerasena Research Assistant, University of Florida From: Karim Soliman via gem5-users <gem5-users@gem5.org> Date: Wednesday, August 9, 2023 at 11:21 PM To: The gem5 Users mailing list <gem5-users@gem5.org> Cc: Karim Soliman <karim.soliman@pua.edu.eg> Subject: [gem5-users] Running PARSEC benchmark on gem5 Garnet [External Email] Hey everyone, For research purposes, I'm trying to run the PARSEC benchmark on Garnet 2D mesh topology.
