Thanks, I'll do it then :)

I built petsc with:
$ ./configure PETSC_DIR=$PWD PETSC_ARCH=arch-kokkos-serial-debug
--with-cc=mpicc --with-cxx=mpicxx --with-fc=0 --with-debugging=0
--prefix=$HOME/build/petsc/debug/install --with-64-bit-indices
--with-shared-libraries --COPTFLAGS=-O3 --CXXOPTFLAGS=-O3 --download-kokkos
Junchao, this is the same problem that I have been having right?

Mark,
Do you have a reproducer using petsc examples?

Can you paste -log_view result so I can see what functions are used?

You do if preconditioners (like AMG) will use it or if using functions like
MatSetValuesBlocked(). If you have uniform block structure, it doesn't hurt.

Yes, most (but not all) of our system test cases fail with the kokkos/cuda or
cuda backends. All of them pass with the CPU-only kokkos backend.

Hi Guys,
Very quick one. Do I need to set the block size with MPIAIJ?
