Creates a PETSCVIEWERBINARY PetscViewer shared by all processors in a communicator.

Synopsis#

#include "petscviewer.h"   
PetscViewer PETSC_VIEWER_BINARY_(MPI_Comm comm)

Collective

Input Parameter#

Options Database Keys#

  • -viewer_binary_filename - filename in which to store the binary data, defaults to binaryoutput

  • -viewer_binary_skip_info - true means do not create .info file for this viewer

  • -viewer_binary_skip_options - true means do not use the options database for this viewer

  • -viewer_binary_skip_header - true means do not store the usual header information in the binary file

  • -viewer_binary_mpiio - true means use the file via MPI-IO, maybe faster for large files and many MPI ranks

Environmental variable#

  • PETSC_VIEWER_BINARY_FILENAME - filename in which to store the binary data, defaults to binaryoutput

Note#

Unlike almost all other PETSc routines, PETSC_VIEWER_BINARY_ does not return an error code. The binary PetscViewer is usually used in the form

XXXView(XXX object, PETSC_VIEWER_BINARY_(comm));
