# PCPARMSSetLocal
Sets the local preconditioner to be used in `PCPARMS`.
## Synopsis
```
#include "petscpc.h"
PetscErrorCode PCPARMSSetLocal(PC pc, PCPARMSLocalType type)
```
Collective
## Input Parameters
- ***pc -*** the preconditioner context
- ***type -*** the local preconditioner type, one of
```none
PC_PARMS_LOCAL_ILU0 - ILU0 preconditioner
PC_PARMS_LOCAL_ILUK - ILU(k) preconditioner
PC_PARMS_LOCAL_ILUT - ILUT preconditioner
PC_PARMS_LOCAL_ARMS - ARMS preconditioner
```
## Options Database Keys
-pc_parms_local [ilu0,iluk,ilut,arms] - Sets local preconditioner
## Notes
For the ARMS preconditioner, one can use either the symmetric ARMS or the non-symmetric
variant (ARMS-ddPQ) by setting the permutation type with PCPARMSSetNonsymPerm().
See the pARMS function `parms_PCILUSetType()` for more information.
