Sets how much data PCAIR stores when reusing the sparsity of the multigrid hierarchy

Synopsis#

PETSC_EXTERN PetscErrorCode PCAIRSetReuseAmount(PC pc, PetscInt input_int)

Logically Collective

Input Parameters#

pc - the PCAIR preconditioner context
input_int - the amount of data to store when -pc_air_reuse_sparsity is enabled

Options Database Key#

-pc_air_reuse_amount amount - how much data to store when -pc_air_reuse_sparsity is enabled: 1 stores only the CF splitting and parallel repartitioning, 2 additionally stores everything needed to reuse sparsity in the SpGEMMs, and 3 stores everything; defaults to 3
