Use -skip_petscrc in the code specific file to skip the .petscrc files 663 - help - [optional] Help message to print, use NULL for no message 664 665 If you wish PETSc code to run ONLY on a subcommunicator of MPI_COMM_WORLD, create that 666 communicator first and assign it to PETSC_COMM_WORLD BEFORE calling PetscInitialize(). Thus if you are running a 667 four process job and two processes will run PETSc and have PetscInitialize() and PetscFinalize() and two process will not, 668 then do this.

This option is useful to debug imbalance within each event, 703 however it slows things down and gives a distorted view of the overall runtime. 704 . -log_trace [filename] - Print traces of all PETSc calls to the screen (useful to determine where a program 705 hangs without running in the debugger). See PetscLogTraceBegin(). 706 . -log_view [:filename:format] - Prints summary of flop and timing information to screen or file, see PetscLogView(). 707 . -log_summary [filename] - (Deprecated, use -log_view) Prints summary of flop and timing information to screen. If the filename is specified the 708 summary is written to the file. See PetscLogView(). 709 . -log_exclude: <vec,mat,pc,ksp,snes> - excludes subset of object classes from logging 710 . -log_all [filename] - Logs extensive profiling information See PetscLogDump(). 711 . -log [filename] - Logs basic profiline information See PetscLogDump(). 712 . -log_mpe [filename] - Creates a logfile viewable by the utility Jumpshot (in MPICH distribution) 713 . -viewfromoptions on,off - Enable or disable XXXSetFromOptions() calls, for applications with many small solves turn this off 714 - -check_pointer_intensity 0,1,2 - if pointers are checked for validity (debug version only), using 0 will result in faster code 715 716 Only one of -log_trace, -log_view, -log_view, -log_all, -log, or -log_mpe may be used at a time 717 718 Options Database Keys for SAWs: 719 + -saws_port <portnumber> - port number to publish SAWs data, default is 8080 720 . -saws_port_auto_select - have SAWs select a new unique port number where it publishes the data, the URL is printed to the screen 721 this is useful when you are running many jobs that utilize SAWs at the same time 722 . -saws_log <filename> - save a log of all SAWs communication 723 . -saws_https <certificate file> - have SAWs use HTTPS instead of HTTP 724 - -saws_root <directory> - allow SAWs to have access to the given directory to search for requested resources and files 725 726 Environmental Variables: 727 + PETSC_TMP - alternative tmp directory 728 . PETSC_SHARED_TMP - tmp is shared by all processes 729 . PETSC_NOT_SHARED_TMP - each process has its own private tmp 730 . PETSC_VIEWER_SOCKET_PORT - socket number to use for socket viewer 731 - PETSC_VIEWER_SOCKET_MACHINE - machine to use for socket viewer to connect to 732 733 734 Level: beginner 735 736 Notes: 737 If for some reason you must call MPI_Init() separately, call 738 it before PetscInitialize(). 739 740 Fortran Version: 741 In Fortran this routine has the format 742 $ call PetscInitialize(file,ierr) 743 744 + ierr - error return code 745 - file - [optional] PETSc database file, also checks ~username/.petscrc and .petscrc use PETSC_NULL_CHARACTER to not check for 746 code specific file.
