[petsc-users] snes/ex19 issue with nvprof

I'm using CUDA 10.1.105 and this looks like a logic bug and not a CUDA
problem.

I added two MatSetType calls that I thought were the right thing to do.
Your error is a type problem and test with DMPlex so the matrix creation
goes through a different code path.

You could try removing them and see if it works.

That is really all there is in this branch at this point other than some
ViennaCL stuff.

I would verify that a fresh pull from master works. I would also
reconfigure. I have just pulled from master and pushed so you can do a
fresh pull.
