Input Parameters#
- pc - the preconditioner context 
- type - variant of - PCASM, one of
      PC_ASM_BASIC       - full interpolation and restriction
      PC_ASM_RESTRICT    - full restriction, local processor interpolation (default)
      PC_ASM_INTERPOLATE - full interpolation, local processor restriction

Note#
if the is_local arguments are passed to PCASMSetLocalSubdomains() then they are used when PC_ASM_RESTRICT has been selected
to limit the local processor interpolation
