PETSC_VIEWER_SOCKET_ - Creates a socket viewer shared by all processors in a communicator.
Collective on MPI_Comm
Input Parameter:
. comm - the MPI communicator to share the socket PetscViewer
Level: intermediate
Options Database Keys:
For use with the default PETSC_VIEWER_SOCKET_WORLD or if
NULL is passed for machine or PETSC_DEFAULT is passed for port
$ -viewer_socket_machine <machine>
$ -viewer_socket_port <port>
Environmental variables:
+ PETSC_VIEWER_SOCKET_PORT portnumber
- PETSC_VIEWER_SOCKET_MACHINE machine name
Notes:
Unlike almost all other PETSc routines, PetscViewer_SOCKET_ does not return
an error code. The socket PetscViewer is usually used in the form
$ XXXView(XXX object,PETSC_VIEWER_SOCKET_(comm));
Currently the only socket client available is MATLAB. See
src/dm/examples/tests/ex12.c and ex12.m for an example of usage.
Connects to a waiting socket and stays connected until PetscViewerDestroy() is called.
Use this for communicating with an interactive MATLAB session, see PETSC_VIEWER_MATLAB_() for writing output to a
.mat file. Use PetscMatlabEngineCreate() or PETSC_MATLAB_ENGINE_(), PETSC_MATLAB_ENGINE_SELF, or PETSC_MATLAB_ENGINE_WORLD
for communicating with a MATLAB Engine
