Use -skip_petscrc in the code specific file to skip the .petscrc files 672 - help - [optional] Help message to print, use NULL for no message 673 674 If you wish PETSc code to run ONLY on a subcommunicator of MPI_COMM_WORLD, create that 675 communicator first and assign it to PETSC_COMM_WORLD BEFORE calling PetscInitialize().

This option is useful to debug imbalance within each event, 712 however it slows things down and gives a distorted view of the overall runtime. 713 . -log_trace [filename] - Print traces of all PETSc calls to the screen (useful to determine where a program 714 hangs without running in the debugger). See PetscLogTraceBegin(). 715 . -log_view [:filename:format] - Prints summary of flop and timing information to screen or file, see PetscLogView(). 716 . -log_summary [filename] - (Deprecated, use -log_view) Prints summary of flop and timing information to screen. If the filename is specified the 717 summary is written to the file. See PetscLogView(). 718 . -log_exclude: <vec,mat,pc,ksp,snes> - excludes subset of object classes from logging 719 . -log_all [filename] - Logs extensive profiling information See PetscLogDump(). 720 . -log [filename] - Logs basic profiline information See PetscLogDump(). 721 . -log_mpe [filename] - Creates a logfile viewable by the utility Jumpshot (in MPICH distribution) 722 . -viewfromoptions on,off - Enable or disable XXXSetFromOptions() calls, for applications with many small solves turn this off 723 - -check_pointer_intensity 0,1,2 - if pointers are checked for validity (debug version only), using 0 will result in faster code 724 725 Only one of -log_trace, -log_view, -log_view, -log_all, -log, or -log_mpe may be used at a time 726 727 Options Database Keys for SAWs: 728 + -saws_port <portnumber> - port number to publish SAWs data, default is 8080 729 . -saws_port_auto_select - have SAWs select a new unique port number where it publishes the data, the URL is printed to the screen 730 this is useful when you are running many jobs that utilize SAWs at the same time 731 . -saws_log <filename> - save a log of all SAWs communication 732 . -saws_https <certificate file> - have SAWs use HTTPS instead of HTTP 733 - -saws_root <directory> - allow SAWs to have access to the given directory to search for requested resources and files 734 735 Environmental Variables: 736 + PETSC_TMP - alternative tmp directory 737 . PETSC_SHARED_TMP - tmp is shared by all processes 738 . PETSC_NOT_SHARED_TMP - each process has its own private tmp 739 . PETSC_VIEWER_SOCKET_PORT - socket number to use for socket viewer 740 - PETSC_VIEWER_SOCKET_MACHINE - machine to use for socket viewer to connect to 741 742 743 Level: beginner 744 745 Notes: 746 If for some reason you must call MPI_Init() separately, call 747 it before PetscInitialize(). 748 749 Fortran Version: 750 In Fortran this routine has the format 751 $ call PetscInitialize(file,ierr) 752 753 + ierr - error return code 754 - file - [optional] PETSc database file, also checks ~username/.petscrc and .petscrc use PETSC_NULL_CHARACTER to not check for 755 code specific file. Use -skip_petscrc in the code specific file to skip the .petscrc files 756 757 Important Fortran Note: 758 In Fortran, you MUST use PETSC_NULL_CHARACTER to indicate a 759 null character string; you CANNOT just use NULL as 760 in the C version.
