Use -skip_petscrc in the code specific file to skip the .petscrc files 623 - help - [optional] Help message to print, use NULL for no message 624 625 If you wish PETSc code to run ONLY on a subcommunicator of MPI_COMM_WORLD, create that 626 communicator first and assign it to PETSC_COMM_WORLD BEFORE calling PetscInitialize().

This option is useful to debug imbalance within each event, 663 however it slows things down and gives a distorted view of the overall runtime. 664 . -log_trace [filename] - Print traces of all PETSc calls to the screen (useful to determine where a program 665 hangs without running in the debugger). See PetscLogTraceBegin(). 666 . -log_view [:filename:format] - Prints summary of flop and timing information to screen or file, see PetscLogView(). 667 . -log_summary [filename] - (Deprecated, use -log_view) Prints summary of flop and timing information to screen. If the filename is specified the 668 summary is written to the file. See PetscLogView(). 669 . -log_exclude: <vec,mat,pc,ksp,snes> - excludes subset of object classes from logging 670 . -log_all [filename] - Logs extensive profiling information See PetscLogDump(). 671 . -log [filename] - Logs basic profiline information See PetscLogDump(). 672 . -log_mpe [filename] - Creates a logfile viewable by the utility Jumpshot (in MPICH distribution) 673 - -check_pointer_intensity 0,1,2 - if pointers are checked for validity (debug version only), using 0 will result in faster code 674 675 Only one of -log_trace, -log_view, -log_view, -log_all, -log, or -log_mpe may be used at a time 676 677 Options Database Keys for SAWs: 678 + -saws_port <portnumber> - port number to publish SAWs data, default is 8080 679 . -saws_port_auto_select - have SAWs select a new unique port number where it publishes the data, the URL is printed to the screen 680 this is useful when you are running many jobs that utilize SAWs at the same time 681 . -saws_log <filename> - save a log of all SAWs communication 682 . -saws_https <certificate file> - have SAWs use HTTPS instead of HTTP 683 - -saws_root <directory> - allow SAWs to have access to the given directory to search for requested resources and files 684 685 Environmental Variables: 686 + PETSC_TMP - alternative tmp directory 687 . PETSC_SHARED_TMP - tmp is shared by all processes 688 . PETSC_NOT_SHARED_TMP - each process has its own private tmp 689 . PETSC_VIEWER_SOCKET_PORT - socket number to use for socket viewer 690 - PETSC_VIEWER_SOCKET_MACHINE - machine to use for socket viewer to connect to 691 692 693 Level: beginner 694 695 Notes: 696 If for some reason you must call MPI_Init() separately, call 697 it before PetscInitialize(). 698 699 Fortran Version: 700 In Fortran this routine has the format 701 $ call PetscInitialize(file,ierr) 702 703 + ierr - error return code 704 - file - [optional] PETSc database file, also checks ~username/.petscrc and .petscrc use PETSC_NULL_CHARACTER to not check for 705 code specific file. Use -skip_petscrc in the code specific file to skip the .petscrc files 706 707 Important Fortran Note: 708 In Fortran, you MUST use PETSC_NULL_CHARACTER to indicate a 709 null character string; you CANNOT just use NULL as 710 in the C version.
