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(). Thus if you are running a 627 four process job and two processes will run PETSc and have PetscInitialize() and PetscFinalize() and two process will not, 628 then do this.

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 . -viewfromoptions on,off - Enable or disable XXXSetFromOptions() calls, for applications with many small solves turn this off 674 - -check_pointer_intensity 0,1,2 - if pointers are checked for validity (debug version only), using 0 will result in faster code 675 676 Only one of -log_trace, -log_view, -log_view, -log_all, -log, or -log_mpe may be used at a time 677 678 Options Database Keys for SAWs: 679 + -saws_port <portnumber> - port number to publish SAWs data, default is 8080 680 . -saws_port_auto_select - have SAWs select a new unique port number where it publishes the data, the URL is printed to the screen 681 this is useful when you are running many jobs that utilize SAWs at the same time 682 . -saws_log <filename> - save a log of all SAWs communication 683 . -saws_https <certificate file> - have SAWs use HTTPS instead of HTTP 684 - -saws_root <directory> - allow SAWs to have access to the given directory to search for requested resources and files 685 686 Environmental Variables: 687 + PETSC_TMP - alternative tmp directory 688 . PETSC_SHARED_TMP - tmp is shared by all processes 689 . PETSC_NOT_SHARED_TMP - each process has its own private tmp 690 . PETSC_VIEWER_SOCKET_PORT - socket number to use for socket viewer 691 - PETSC_VIEWER_SOCKET_MACHINE - machine to use for socket viewer to connect to 692 693 694 Level: beginner 695 696 Notes: 697 If for some reason you must call MPI_Init() separately, call 698 it before PetscInitialize(). 699 700 Fortran Version: 701 In Fortran this routine has the format 702 $ call PetscInitialize(file,ierr) 703 704 + ierr - error return code 705 - file - [optional] PETSc database file, also checks ~username/.petscrc and .petscrc use PETSC_NULL_CHARACTER to not check for 706 code specific file. Use -skip_petscrc in the code specific file to skip the .petscrc files 707 708 Important Fortran Note: 709 In Fortran, you MUST use PETSC_NULL_CHARACTER to indicate a 710 null character string; you CANNOT just use NULL as 711 in the C version.
