[gem5-users] GCN3 - Polybench GPU - SPEC 17 - Errors

2021-10-09 Thread Sampad Mohapatra via gem5-users
Hi All, I am running gem5 v21.0.0.0, rocm v1.6.x (built from source). The simulations run one host CPU (its pair runs a tiny binary and ends exec quickly) to launch GPU benchmark (hipified Polybench GPU) and one CPU of a separate core-pair(its 2nd core runs a lightweight binary and ends exec quick

Hi Sampad, I have not seen anyone attempt to run workloads in a way you are attempting, so I can't offer every solution, but here are a few things I noticed: - Why are you still using ROCm 1.6.x? And why did you build it from source? I strongly recommend using the built-in docker support (which

Hi Matt, Thanks for the quick reply. I am running the benchmarks on research clusters where running docker is not permitted and hence I have to build everything and install locally. I have made modifications to the coherence protocol and porting it to a newer Gem5 version may take some time and h

If you cannot use docker, then I recommend using the commands Kyle had in the old dockers when installing ROCm. Manually building like you are is extremely error prone. I don't know exactly what the problem(s) is, but I'm pretty sure it's HCC_AMDGPU_TARGET, not HSA_AMDGPU_GPU_TARGET. I'm pretty
