PetscSortMPIInt#

Sorts an array of PetscMPIInt in place in increasing order.

Synopsis#

#include "petscsys.h"  
PetscErrorCode PetscSortMPIInt(PetscInt n, PetscMPIInt X[])

Not Collective

Input Parameters#

  • n - number of values

  • X - array of integers

Note#

This function serves as an alternative to PetscMPIIntSortSemiOrdered(), and may perform faster especially if the array is completely random. There are exceptions to this and so it is highly recommended that the user benchmark their code to see which routine is fastest.
