Use -skip_petscrc in the code specific file to skip the .petscrc files 665 - help - [optional] Help message to print, use NULL for no message 666 667 If you wish PETSc code to run ONLY on a subcommunicator of MPI_COMM_WORLD, create that 668 communicator first and assign it to PETSC_COMM_WORLD BEFORE calling PetscInitialize(). Thus if you are running a 669 four process job and two processes will run PETSc and have PetscInitialize() and PetscFinalize() and two process will not, 670 then do this.

This option is useful to debug imbalance within each event, 705 however it slows things down and gives a distorted view of the overall runtime. 706 . -log_trace [filename] - Print traces of all PETSc calls to the screen (useful to determine where a program 707 hangs without running in the debugger). See PetscLogTraceBegin(). 708 . -log_view [:filename:format] - Prints summary of flop and timing information to screen or file, see PetscLogView(). 709 . -log_summary [filename] - (Deprecated, use -log_view) Prints summary of flop and timing information to screen. If the filename is specified the 710 summary is written to the file. See PetscLogView(). 711 . -log_exclude: <vec,mat,pc,ksp,snes> - excludes subset of object classes from logging 712 . -log_all [filename] - Logs extensive profiling information See PetscLogDump(). 713 . -log [filename] - Logs basic profiline information See PetscLogDump(). 714 . -log_mpe [filename] - Creates a logfile viewable by the utility Jumpshot (in MPICH distribution) 715 . -viewfromoptions on,off - Enable or disable XXXSetFromOptions() calls, for applications with many small solves turn this off 716 - -check_pointer_intensity 0,1,2 - if pointers are checked for validity (debug version only), using 0 will result in faster code 717 718 Only one of -log_trace, -log_view, -log_view, -log_all, -log, or -log_mpe may be used at a time 719 720 Options Database Keys for SAWs: 721 + -saws_port <portnumber> - port number to publish SAWs data, default is 8080 722 . -saws_port_auto_select - have SAWs select a new unique port number where it publishes the data, the URL is printed to the screen 723 this is useful when you are running many jobs that utilize SAWs at the same time 724 . -saws_log <filename> - save a log of all SAWs communication 725 . -saws_https <certificate file> - have SAWs use HTTPS instead of HTTP 726 - -saws_root <directory> - allow SAWs to have access to the given directory to search for requested resources and files 727 728 Environmental Variables: 729 + PETSC_TMP - alternative tmp directory 730 . PETSC_SHARED_TMP - tmp is shared by all processes 731 . PETSC_NOT_SHARED_TMP - each process has its own private tmp 732 . PETSC_VIEWER_SOCKET_PORT - socket number to use for socket viewer 733 - PETSC_VIEWER_SOCKET_MACHINE - machine to use for socket viewer to connect to 734 735 736 Level: beginner 737 738 Notes: 739 If for some reason you must call MPI_Init() separately, call 740 it before PetscInitialize(). 741 742 Fortran Version: 743 In Fortran this routine has the format 744 $ call PetscInitialize(file,ierr) 745 746 + ierr - error return code 747 - file - [optional] PETSc database file, also checks ~username/.petscrc and .petscrc use PETSC_NULL_CHARACTER to not check for 748 code specific file. Use -skip_petscrc in the code specific file to skip the .petscrc files 749 750 Important Fortran Note: 751 In Fortran, you MUST use PETSC_NULL_CHARACTER to indicate a 752 null character string; you CANNOT just use NULL as 753 in the C version.
