[petsc-dev] PETSc GPU example

Dear PETSc team, I am interested in a careful evaluation of PETSc GPU performance in our INL cluster. Any example in PETSc that can show GPU speedup with solving a nonlinear equation? I talked to Junchao; he suggested that I try SNES/tutorial/ex56. I tried that, but I could not find any speedup using the GPU. I could attach some results of "log_view" later if we would like to see that. Appreciate any instructions/comments about running a simple PETSc GPU example to get a speedup. Thanks, Fande
