I am getting this error. This is in GAMG/HEM setup. PtAP for the coarse grid construction works, but I call this in a graph routine (/global/u2/m/madams/petsc/src/mat/coarsen/impls/hem/hem.c:1043).
Also, this PtAP does not need to be on the GPU anyway because P is extremely sparse ... can I pin, say P, to the CPU to keep this all on the host?
