Hi Matt, Thanks for the detailed response and link to the docker image.
I have been looking at the post https://www.mail-archive.com/gem5-users@gem5.org/msg15909.html <https://www.mail-archive.com/gem5-users@gem5.org/msg15909.html>, and I used several hints regarding rocm version, and changes to the library paths in apu_se.py listed in the post. In an alternate post https://www.mail-archive.com/gem5-users@gem5.org/msg16275.html <https://www.mail-archive.com/gem5-users@gem5.org/msg16275.html>, Anthony recommended some specific commit IDs for ROCr, ROCt, and HCC. I am yet to install these ROC packages with these specific commit IDs. We will try HIP and the docker image you have provided. Thanks again. > On Mar 21, 2020, at 4:28 PM, Matt Sinclair <mattdsincl...@gmail.com> wrote: > > Hi Anirudh, > > This question has been asked several times before.
