Use -skip_petscrc in the code specific file to skip the .petscrc files 670 - help - [optional] Help message to print, use NULL for no message 671 672 If you wish PETSc code to run ONLY on a subcommunicator of MPI_COMM_WORLD, create that 673 communicator first and assign it to PETSC_COMM_WORLD BEFORE calling PetscInitialize().

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