This option is useful to debug imbalance within each event, 702 however it slows things down and gives a distorted view of the overall runtime. 703 . -log_trace [filename] - Print traces of all PETSc calls to the screen (useful to determine where a program 704 hangs without running in the debugger). See PetscLogTraceBegin(). 705 . -log_view [:filename:format] - Prints summary of flop and timing information to screen or file, see PetscLogView(). 706 . -log_summary [filename] - (Deprecated, use -log_view) Prints summary of flop and timing information to screen. If the filename is specified the 707 summary is written to the file. See PetscLogView(). 708 . -log_exclude: <vec,mat,pc,ksp,snes> - excludes subset of object classes from logging 709 . -log_all [filename] - Logs extensive profiling information See PetscLogDump(). 710 . -log [filename] - Logs basic profiline information See PetscLogDump(). 711 . -log_mpe [filename] - Creates a logfile viewable by the utility Jumpshot (in MPICH distribution) 712 . -viewfromoptions on,off - Enable or disable XXXSetFromOptions() calls, for applications with many small solves turn this off 713 - -check_pointer_intensity 0,1,2 - if pointers are checked for validity (debug version only), using 0 will result in faster code 714 715 Only one of -log_trace, -log_view, -log_view, -log_all, -log, or -log_mpe may be used at a time 716 717 Options Database Keys for SAWs: 718 + -saws_port <portnumber> - port number to publish SAWs data, default is 8080 719 . -saws_port_auto_select - have SAWs select a new unique port number where it publishes the data, the URL is printed to the screen 720 this is useful when you are running many jobs that utilize SAWs at the same time 721 . -saws_log <filename> - save a log of all SAWs communication 722 . -saws_https <certificate file> - have SAWs use HTTPS instead of HTTP 723 - -saws_root <directory> - allow SAWs to have access to the given directory to search for requested resources and files 724 725 Environmental Variables: 726 + PETSC_TMP - alternative tmp directory 727 . PETSC_SHARED_TMP - tmp is shared by all processes 728 . PETSC_NOT_SHARED_TMP - each process has its own private tmp 729 . PETSC_VIEWER_SOCKET_PORT - socket number to use for socket viewer 730 - PETSC_VIEWER_SOCKET_MACHINE - machine to use for socket viewer to connect to 731 732 733 Level: beginner 734 735 Notes: 736 If for some reason you must call MPI_Init() separately, call 737 it before PetscInitialize(). 738 739 Fortran Version: 740 In Fortran this routine has the format 741 $ call PetscInitialize(file,ierr) 742 743 + ierr - error return code 744 - file - [optional] PETSc database file, also checks ~username/.petscrc and .petscrc use PETSC_NULL_CHARACTER to not check for 745 code specific file.
