Use -skip_petscrc in the code specific file to skip the .petscrc files 668 - help - [optional] Help message to print, use NULL for no message 669 670 If you wish PETSc code to run ONLY on a subcommunicator of MPI_COMM_WORLD, create that 671 communicator first and assign it to PETSC_COMM_WORLD BEFORE calling PetscInitialize().

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