I am trying to port CHAI benchmarks similarly to gem5-resources/src/gpu/pannotia . I was able to HIPify (through the perl script + some manual changes) all the code files, and ran the BFS p

[gem5-users] Re: Replacing CPU model in GPU-FS

It appears the host part of GPU applications are indeed executed on KVM, from: https://www.gem5.org/assets/files/workshop-isca-2023/slides/improving-gem5s-gpufs-support.pdf . A few more questions: 1. I missed that it isn't mentioned that O3 CPU models aren't supported -- would that be as easy as c

Wrong build; it works when built for gfx-8 (per readme) $ make release-gfx8 in heterosync directory. On Tue, Jun 20, 2023, 6:26 PM Anoop Mysore wrote: > Oh I see, that makes sense; I was on ROCm 5.1.0. > I am now running on docker and the square test works as expected. > I don't see a ready-made

[gem5-users] Re: bad ioctl error in gpu_comput_driver.cc

Oh I see, that makes sense; I was on ROCm 5.1.0. I am now running on docker and the square test works as expected. I don't see a ready-made config for full system emulation with gcn3 -- is that available someplace else or should I figure out how to build one? I think I need that because when I try
