Use -skip_petscrc in the code specific file to skip the .petscrc files 625 - help - [optional] Help message to print, use NULL for no message 626 627 If you wish PETSc code to run ONLY on a subcommunicator of MPI_COMM_WORLD, create that 628 communicator first and assign it to PETSC_COMM_WORLD BEFORE calling PetscInitialize().

This option is useful to debug imbalance within each event, 665 however it slows things down and gives a distorted view of the overall runtime. 666 . -log_trace [filename] - Print traces of all PETSc calls to the screen (useful to determine where a program 667 hangs without running in the debugger). See PetscLogTraceBegin(). 668 . -log_view [:filename:format] - Prints summary of flop and timing information to screen or file, see PetscLogView(). 669 . -log_summary [filename] - (Deprecated, use -log_view) Prints summary of flop and timing information to screen. If the filename is specified the 670 summary is written to the file. See PetscLogView(). 671 . -log_exclude: <vec,mat,pc,ksp,snes> - excludes subset of object classes from logging 672 . -log_all [filename] - Logs extensive profiling information See PetscLogDump(). 673 . -log [filename] - Logs basic profiline information See PetscLogDump(). 674 . -log_mpe [filename] - Creates a logfile viewable by the utility Jumpshot (in MPICH distribution) 675 . -viewfromoptions on,off - Enable or disable XXXSetFromOptions() calls, for applications with many small solves turn this off 676 - -check_pointer_intensity 0,1,2 - if pointers are checked for validity (debug version only), using 0 will result in faster code 677 678 Only one of -log_trace, -log_view, -log_view, -log_all, -log, or -log_mpe may be used at a time 679 680 Options Database Keys for SAWs: 681 + -saws_port <portnumber> - port number to publish SAWs data, default is 8080 682 . -saws_port_auto_select - have SAWs select a new unique port number where it publishes the data, the URL is printed to the screen 683 this is useful when you are running many jobs that utilize SAWs at the same time 684 . -saws_log <filename> - save a log of all SAWs communication 685 . -saws_https <certificate file> - have SAWs use HTTPS instead of HTTP 686 - -saws_root <directory> - allow SAWs to have access to the given directory to search for requested resources and files 687 688 Environmental Variables: 689 + PETSC_TMP - alternative tmp directory 690 . PETSC_SHARED_TMP - tmp is shared by all processes 691 . PETSC_NOT_SHARED_TMP - each process has its own private tmp 692 . PETSC_VIEWER_SOCKET_PORT - socket number to use for socket viewer 693 - PETSC_VIEWER_SOCKET_MACHINE - machine to use for socket viewer to connect to 694 695 696 Level: beginner 697 698 Notes: 699 If for some reason you must call MPI_Init() separately, call 700 it before PetscInitialize(). 701 702 Fortran Version: 703 In Fortran this routine has the format 704 $ call PetscInitialize(file,ierr) 705 706 + ierr - error return code 707 - file - [optional] PETSc database file, also checks ~username/.petscrc and .petscrc use PETSC_NULL_CHARACTER to not check for 708 code specific file. Use -skip_petscrc in the code specific file to skip the .petscrc files 709 710 Important Fortran Note: 711 In Fortran, you MUST use PETSC_NULL_CHARACTER to indicate a 712 null character string; you CANNOT just use NULL as 713 in the C version.
