Interestingly, we got some "errors" on GPUs with this change, see below. So this means we actually hit that line of changing coarsen_type
. Should we go ahead to change the .saved
files?

Just to document what we just talked about, yes I think you should change the .saved
files. Thanks!
This PR removes a potential
coarsen_type
change in AMG setup on GPUs. The CPU code remains the same.
