[petsc-users] PetscCommGetNewTag issue

[Fande Kong]

Hi all,

I make a very simple code, but run into some error messages.

Code:

#include <petsc.h>
static char help[] = " simple test.\n\n";

#undef __FUNCT__
#define __FUNCT__ "main"
int main(int argc,char **argv)
{
  PetscMPIInt                   tag = 0;
  PetscErrorCode                ierr;

  ierr = PetscInitialize(&argc,&argv,(char *)0,help);CHKERRQ(ierr);
  ierr = PetscCommGetNewTag(PETSC_COMM_WORLD,&tag);CHKERRQ(ierr);
  ierr = PetscPrintf(PETSC_COMM_SELF," tag %d \n", tag);CHKERRQ(ierr);
  ierr = PetscFinalize();CHKERRQ(ierr);
}


Run: mpirun -np 2 ./Test
