Hello, gem5-gpu is the combination of gem5 and gpgpu-sim. You may find more information here: https://gem5-gpu.cs.wisc.edu/wiki/ If you are not planning to simulate gpus sticking to gem5 might be a better idea.
To create checkpoints you have two options. One is the command line option "--checkpoint-at-end". This will create a checkpoint when your simulation ends. The second way is to use use m5 commands (which I think the easier way). There is a script file: "configs/boot/hack_back_ckpt.rcS" to see more on this. You need to run the simulation with this script first. It creates a checkpoint and stops. The second time (when restored from a checkpoint), you use your own script.

When I search it online, someone use gem5.gpu to create checkpoint. What is the difference between gem5 and gem5-gpu? In my opinion they are different simulators. 2. After checking some document I still have no idea about the checkpoint. I don't know how to start to create it. Could anyone give me any idea to do it? Thanks for your time and reply. with best regards Yunxia Zhu _______________________________________________ gem5-users mailing list gem5-users@gem5.org http://m5sim.org/cgi-bin/mailman/listinfo/gem5-users
