8: PetscViewerSAWsOpen - Opens an SAWs PetscViewer.
10: Collective on MPI_Comm
12: Input Parameters:
13: . comm - the MPI communicator
15: Output Parameter:
16: . lab - the PetscViewer
18: Options Database Keys:
19: + -saws_port <port number> - port number where you are running SAWs client
20: . -xxx_view saws - publish the object xxx
21: - -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
22: the user unblocks the problem with an external tool that access the object with SAWS
24: Level: advanced
26: Fortran Note:
27: This routine is not supported in Fortran.
30: Notes:
31: Unlike other viewers that only access the object being viewed on the call to XXXView(object,viewer) the SAWs viewer allows
32: one to view the object asynchronously as the program continues to run. One can remove SAWs access to the object with a call to
33: PetscObjectSAWsViewOff().
35: Information about the SAWs is available via http://bitbucket.org/saws/saws
