OK. Got it running. Needed the code change below and to compile with -DHIP_WARP64=OFF. Is there someplace I can contribute a patch to get this change into the next release?

Thanks,

Trevor

I was able to get it to compile by modifying line 71 of src/pmemd/src/cuda/ptxmacros. h to #if defined(__gfx1030__) || defined(__gfx1031__) || defined(__gfx1100__) But now when I try and run I am getting errors like these Memory access fault

Is there a specific driver or kernel requirement? Other gpu workloads run fine on this machine like hip and opencl examples as well as benchmarking programs like clpeak.



Thanks,
