PetscLayoutSetUp

given a map where you have set either the global or local size sets up the map so that it may be used.

Synopsis

#undef __FUNCT__
#define __FUNCT__ "PetscLayoutSetUp"
PetscErrorCode  PetscLayoutSetUp(PetscLayout map)
Collective on MPI_Comm

Input Parameters

map -pointer to the map

Notes: Typical calling sequence PetscLayoutCreate(MPI_Comm,PetscLayout *); PetscLayoutSetBlockSize(PetscLayout,1); PetscLayoutSetSize(PetscLayout,n) or PetscLayoutSetLocalSize(PetscLayout,N); or both PetscLayoutSetUp(PetscLayout); PetscLayoutGetSize(PetscLayout,PetscInt *);

If the local size, global size are already set and range exists then this does nothing.
