PETSc version 3.16.6

PETSC_VIEWER_BINARY_

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

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

Collective

comm

- the MPI communicator to share the binary PetscViewer

	-viewer_binary_filename <name>	- 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

PETSC_VIEWER_BINARY_FILENAME

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

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));
