Dear PETSc’s developers,
In the context of unstructured applications developed by PETSc’s DMPlex,
if the ASM is used for preconditioning, is it algebraic (based on matrix graph)
or geometric (based on Metis partition)?
When the ASM preconditioner is associated with a specific DM object, I
found there is only the implementation of DMCreateDomainDecomposition for DA
in PCSetUp_ASM, and there is no implementation for DMPlex. So I guess the ASM
is algebraic for DMPlex, is that right ? Best, Wenpeng
