Use -skip_petscrc in the code specific file to skip the .petscrc files 666 - help - [optional] Help message to print, use NULL for no message 667 668 If you wish PETSc code to run ONLY on a subcommunicator of MPI_COMM_WORLD, create that 669 communicator first and assign it to PETSC_COMM_WORLD BEFORE calling PetscInitialize(). Thus if you are running a 670 four process job and two processes will run PETSc and have PetscInitialize() and PetscFinalize() and two process will not, 671 then do this. If ALL processes in the job are using PetscInitialize() and PetscFinalize() then you don't need to do this, even 672 if different subcommunicators of the job are doing different things with PETSc. 673 674 Options Database Keys: 675 + -help [intro] - prints help method for each option; if intro is given the program stops after printing the introductory help message 676 . -start_in_debugger [noxterm,dbx,xdb,gdb,...] - Starts program in debugger 677 . -on_error_attach_debugger [noxterm,dbx,xdb,gdb,...] - Starts debugger when error detected 678 . -on_error_emacs <machinename> - causes emacsclient to jump to error file 679 . -on_error_abort - calls abort() when error detected (no traceback) 680 . -on_error_mpiabort - calls MPI_abort() when error detected 681 . -error_output_stderr - prints error messages to stderr instead of the default stdout 682 . -error_output_none - does not print the error messages (but handles errors in the same way as if this was not called) 683 . -debugger_nodes [node1,node2,...] - Indicates nodes to start in debugger 684 . -debugger_pause [sleeptime] (in seconds) - Pauses debugger 685 . -stop_for_debugger - Print message on how to attach debugger manually to 686 process and wait (-debugger_pause) seconds for attachment 687 . -malloc - Indicates use of PETSc error-checking malloc (on by default for debug version of libraries) 688 . -malloc no - Indicates not to use error-checking malloc 689 . -malloc_debug - check for memory corruption at EVERY malloc or free 690 . -malloc_dump - prints a list of all unfreed memory at the end of the run 691 . -malloc_test - like -malloc_dump -malloc_debug, but only active for debugging builds 692 . -fp_trap - Stops on floating point exceptions (Note that on the 693 IBM RS6000 this slows code by at least a factor of 10.) 694 . -no_signal_handler - Indicates not to trap error signals 695 . -shared_tmp - indicates /tmp directory is shared by all processors 696 . -not_shared_tmp - each processor has own /tmp 697 . -tmp - alternative name of /tmp directory 698 . -get_total_flops - returns total flops done by all processors 699 - -memory_view - Print memory usage at end of run 700 701 Options Database Keys for Profiling: 702 See Users-Manual: ch_profiling for details. 703 + -info <optional filename> - Prints verbose information to the screen 704 . -info_exclude <null,vec,mat,pc,ksp,snes,ts> - Excludes some of the verbose messages 705 . -log_sync - Enable barrier synchronization for all events. This option is useful to debug imbalance within each event, 706 however it slows things down and gives a distorted view of the overall runtime. 707 . -log_trace [filename] - Print traces of all PETSc calls to the screen (useful to determine where a program 708 hangs without running in the debugger). See PetscLogTraceBegin(). 709 . -log_view [:filename:format] - Prints summary of flop and timing information to screen or file, see PetscLogView(). 710 . -log_summary [filename] - (Deprecated, use -log_view) Prints summary of flop and timing information to screen. If the filename is specified the 711 summary is written to the file. See PetscLogView(). 712 . -log_exclude: <vec,mat,pc,ksp,snes> - excludes subset of object classes from logging 713 . -log_all [filename] - Logs extensive profiling information See PetscLogDump(). 714 . -log [filename] - Logs basic profiline information See PetscLogDump(). 715 . -log_mpe [filename] - Creates a logfile viewable by the utility Jumpshot (in MPICH distribution) 716 . -viewfromoptions on,off - Enable or disable XXXSetFromOptions() calls, for applications with many small solves turn this off 717 - -check_pointer_intensity 0,1,2 - if pointers are checked for validity (debug version only), using 0 will result in faster code 718 719 Only one of -log_trace, -log_view, -log_view, -log_all, -log, or -log_mpe may be used at a time 720 721 Options Database Keys for SAWs: 722 + -saws_port <portnumber> - port number to publish SAWs data, default is 8080 723 . -saws_port_auto_select - have SAWs select a new unique port number where it publishes the data, the URL is printed to the screen 724 this is useful when you are running many jobs that utilize SAWs at the same time 725 . -saws_log <filename> - save a log of all SAWs communication 726 . -saws_https <certificate file> - have SAWs use HTTPS instead of HTTP 727 - -saws_root <directory> - allow SAWs to have access to the given directory to search for requested resources and files 728 729 Environmental Variables: 730 + PETSC_TMP - alternative tmp directory 731 . PETSC_SHARED_TMP - tmp is shared by all processes 732 . PETSC_NOT_SHARED_TMP - each process has its own private tmp 733 . PETSC_VIEWER_SOCKET_PORT - socket number to use for socket viewer 734 - PETSC_VIEWER_SOCKET_MACHINE - machine to use for socket viewer to connect to 735 736 737 Level: beginner 738 739 Notes: 740 If for some reason you must call MPI_Init() separately, call 741 it before PetscInitialize(). 742 743 Fortran Version: 744 In Fortran this routine has the format 745 $ call PetscInitialize(file,ierr) 746 747 + ierr - error return code 748 - file - [optional] PETSc database file, also checks ~username/.petscrc and .petscrc use PETSC_NULL_CHARACTER to not check for 749 code specific file. Use -skip_petscrc in the code specific file to skip the .petscrc files 750 751 Important Fortran Note: 752 In Fortran, you MUST use PETSC_NULL_CHARACTER to indicate a 753 null character string; you CANNOT just use NULL as 754 in the C version.
