The test do run, but I noticed in my logs that VecCopy was not done on the GPU. I looked at the code and VecCopy_SeqCUDA is there. It looks like it should be used. So I put a breakpoint in DDT but ddt failed when it called some simple CUDA method in PetscInitialize. cuda-memcheck fails as I showed. Valgrind also has all kinds of errors but it runs. I am thinking the libs are messed up. I am trying an older CUDA now. I might try nvhpc next. Thanks, Mark On Sun, Sep 26, 2021 at 4:53 PM Junchao Zhang <[email protected]> wrote:
Mark, without cuda-memcheck, did the test run? --Junchao Zhang

FYI, I am getting this with cuda-memcheck on Summit with CUDA 11.0.3:
jsrun -n 48 -a 6 -c 6 -g 1 -r 6 --smpiargs -gpu cuda-memcheck ../ex13-cu -dm_plex_box_faces 4,6,12 -petscpartitioner_simple_node_grid 2,2,2 -dm_plex_box_upper 2,3,6 -petscpartitioner_simple_process_grid 2,3,6 -dm_refine 3 -dm_mat_type aijcusparse -dm_vec_type cuda -dm_view
This job runs with Kokkos and it runs with these 8 nodes with -dm_refine 2 instead of 3. And it runs with the 1 node version of this test.
Thanks, Mark
