[petsc-dev] sm_70

[Mark Adams]

I see kokkos and hyper have a sm_70 flag, but I don't see one for PETSc.

It looks like you have to specify this to get modern atomics to work in
Cuda. I get:

/ccs/home/adams/petsc/include/petscaijdevice.h(99): error: no instance of
overloaded function "atomicAdd" matches the argument list
            argument types are: (double *, double)

I tried using a Kokkos configuration, thinking I could get these sm_70
flags, but that did not work.

Any ideas?
