Synopsis#

#include "petscsys.h"  */
PetscErrorCode PetscViewerSAWsOpen(MPI_Comm comm, PetscViewer *lab)

Collective; No Fortran Support

Input Parameter#

  • comm - the MPI communicator

Output Parameter#

Options Database Keys#

  • -saws_port - port number where you are running SAWs client

  • -xxx_view saws - publish the object xxx

  • -xxx_saws_block - blocks the program at the end of a critical point (for KSP and SNES it is the end of a solve) until the user unblocks the problem with an external tool that access the object with SAWS

Notes#

Unlike other viewers that only access the object being viewed on the call to XXXView(object,viewer) the SAWs viewer allows one to view the object asynchronously as the program continues to run. One can remove SAWs access to the object with a call to PetscObjectSAWsViewOff().

Information about the SAWs is available via https://bitbucket.org/saws/saws
