Refer to this thread https://www.mail-archive.com/gem5-users@gem5.org/msg16276.html, with "--amdgpu-target=gfx801" to the link flag, both CoMD and lulesh can run to complete Matt Sinclair <mattdsincl...@gmail.com<mailto:mattdsincl...@gmail.com>> 於 2019年11月22日 週五 下午11:48寫道： Hi Andrew, Normally this error indicates that something with your ROCm setup is wrong -- you can look through the mailing list archive and see a few examples of people with the same types of errors along with the suggestions (e.g., what kind of traces) to get to start debugging the problem. Why did you install ROCm 1.6.1? If you look at the wiki, AMD suggests using 1.6.x instead: http://gem5.org/GPU_Models#ROCm_tool_chain_and_software_stack. I can't promise that changing from 1.6.1 to 1.6.x will solve your problem, but it would be a good start/thing to check. Also, I'm not familiar with this sample program -- does it assume the device is a discrete GPU? If so, the gem5 AMD GPU model assumes the GPU is tightly coupled and cache coherent. So you would need to remove those copies (although it appears your failure is happening sooner than that).
