#include "petscpc.h" PetscErrorCode PCASMSetTotalSubdomains(PC pc,PetscInt N,IS is[],IS is_local[])Collective on PC Many br
pc | - the preconditioner context Many br | |
N | - the number of subdomains for all processors Many br | |
is | - the index sets that define the subdomains for all processors Many br(or NULL to ask PETSc to compe up with subdomains) Many br | |
is_local | - the index sets that define the local part of the subdomains for this processor Many br(or NULL to use the default of 1 subdomain per process) Many br |
By default the ASM preconditioner uses 1 block per processor. Many br
These index sets cannot be destroyed until after completion of the Many brlinear solves for which the ASM preconditioner is being used. Many br
Use PCASMSetLocalSubdomains() to set local subdomains. Many br
The IS numbering is in the parallel, global numbering of the vector for both is and is_local Many br
