PetscSortMPIInt

Sorts an array of MPI integers 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

Notes

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__ recomended that the user benchmark their code to see which routine is fastest.
