[petsc-dev] Do not use PetscSequentialPhaseBegin/End to attempt to control stdout

[Smith, Barry F.]

  It does not work!  Use PetscViewerASCIISyncronizedPrintf() and PetscViewerGetSubviewer() as needed

  These codes break the automated testing because once in a great while the output is in a different order.



  ierr = PetscSequentialPhaseBegin(PETSC_COMM_WORLD,1);CHKERRQ(ierr);
  ierr = PetscViewerASCIIPrintf(PETSC_VIEWER_STDOUT_SELF, "[%d] ==========================\n",rank);CHKERRQ(ierr);
  for (d=depth-1; d>=0; d--) {
    ierr = PetscViewerASCIIPrintf(PETSC_VIEWER_STDOUT_SELF, "depth %D ---------------\n",d);CHKERRQ(ierr);
    ierr = PetscSectionView(sects[d], PETSC_VIEWER_STDOUT_SELF);CHKERRQ(ierr);
    ierr = ISView(iss[d], PETSC_VIEWER_STDOUT_SELF);CHKERRQ(ierr);
  }
  ierr = PetscSequentialPhaseEnd(PETSC_COMM_WORLD,1);CHKERRQ(ierr);


  Thanks
