Use -skip_petscrc in the code specific file to skip the .petscrc files 676 - help - [optional] Help message to print, use NULL for no message 677 678 If you wish PETSc code to run ONLY on a subcommunicator of MPI_COMM_WORLD, create that 679 communicator first and assign it to PETSC_COMM_WORLD BEFORE calling PetscInitialize().

This option is useful to debug imbalance within each event, 716 however it slows things down and gives a distorted view of the overall runtime. 717 . -log_trace [filename] - Print traces of all PETSc calls to the screen (useful to determine where a program 718 hangs without running in the debugger). See PetscLogTraceBegin(). 719 . -log_view [:filename:format] - Prints summary of flop and timing information to screen or file, see PetscLogView(). 720 . -log_summary [filename] - (Deprecated, use -log_view) Prints summary of flop and timing information to screen. If the filename is specified the 721 summary is written to the file. See PetscLogView(). 722 . -log_exclude: <vec,mat,pc,ksp,snes> - excludes subset of object classes from logging 723 . -log_all [filename] - Logs extensive profiling information See PetscLogDump(). 724 . -log [filename] - Logs basic profiline information See PetscLogDump(). 725 . -log_mpe [filename] - Creates a logfile viewable by the utility Jumpshot (in MPICH distribution) 726 . -viewfromoptions on,off - Enable or disable XXXSetFromOptions() calls, for applications with many small solves turn this off 727 - -check_pointer_intensity 0,1,2 - if pointers are checked for validity (debug version only), using 0 will result in faster code 728 729 Only one of -log_trace, -log_view, -log_view, -log_all, -log, or -log_mpe may be used at a time 730 731 Options Database Keys for SAWs: 732 + -saws_port <portnumber> - port number to publish SAWs data, default is 8080 733 . -saws_port_auto_select - have SAWs select a new unique port number where it publishes the data, the URL is printed to the screen 734 this is useful when you are running many jobs that utilize SAWs at the same time 735 . -saws_log <filename> - save a log of all SAWs communication 736 . -saws_https <certificate file> - have SAWs use HTTPS instead of HTTP 737 - -saws_root <directory> - allow SAWs to have access to the given directory to search for requested resources and files 738 739 Environmental Variables: 740 + PETSC_TMP - alternative tmp directory 741 . PETSC_SHARED_TMP - tmp is shared by all processes 742 . PETSC_NOT_SHARED_TMP - each process has its own private tmp 743 . PETSC_VIEWER_SOCKET_PORT - socket number to use for socket viewer 744 - PETSC_VIEWER_SOCKET_MACHINE - machine to use for socket viewer to connect to 745 746 747 Level: beginner 748 749 Notes: 750 If for some reason you must call MPI_Init() separately, call 751 it before PetscInitialize(). 752 753 Fortran Version: 754 In Fortran this routine has the format 755 $ call PetscInitialize(file,ierr) 756 757 + ierr - error return code 758 - file - [optional] PETSc database file, also checks ~username/.petscrc and .petscrc use PETSC_NULL_CHARACTER to not check for 759 code specific file. Use -skip_petscrc in the code specific file to skip the .petscrc files 760 761 Important Fortran Note: 762 In Fortran, you MUST use PETSC_NULL_CHARACTER to indicate a 763 null character string; you CANNOT just use NULL as 764 in the C version.
