674: PetscInitialize - Initializes the PETSc database and MPI.
675: PetscInitialize() calls MPI_Init() if that has yet to be called,
676: so this routine should always be called near the beginning of
677: your program -- usually the very first line!
679: Collective on MPI_COMM_WORLD or PETSC_COMM_WORLD if it has been set
681: Input Parameters:
682: + argc - count of number of command line arguments
683: . args - the command line arguments
684: . file - [optional] PETSc database file, also checks ~username/.petscrc and .petscrc use NULL to not check for
685: code specific file. Use -skip_petscrc in the code specific file to skip the .petscrc files
686: - help - [optional] Help message to print, use NULL for no message
688: If you wish PETSc code to run ONLY on a subcommunicator of MPI_COMM_WORLD, create that
689: communicator first and assign it to PETSC_COMM_WORLD BEFORE calling PetscInitialize(). Thus if you are running a
690: four process job and two processes will run PETSc and have PetscInitialize() and PetscFinalize() and two process will not,
691: then do this. If ALL processes in the job are using PetscInitialize() and PetscFinalize() then you don't need to do this, even
692: if different subcommunicators of the job are doing different things with PETSc.
694: Options Database Keys:
695: + -help [intro] - prints help method for each option; if intro is given the program stops after printing the introductory help message
696: . -start_in_debugger [noxterm,dbx,xdb,gdb,...] - Starts program in debugger
697: . -on_error_attach_debugger [noxterm,dbx,xdb,gdb,...] - Starts debugger when error detected
698: . -on_error_emacs <machinename> - causes emacsclient to jump to error file
699: . -on_error_abort - calls abort() when error detected (no traceback)
700: . -on_error_mpiabort - calls MPI_abort() when error detected
701: . -error_output_stderr - prints error messages to stderr instead of the default stdout
702: . -error_output_none - does not print the error messages (but handles errors in the same way as if this was not called)
703: . -debugger_nodes [node1,node2,...] - Indicates nodes to start in debugger
704: . -debugger_pause [sleeptime] (in seconds) - Pauses debugger
705: . -stop_for_debugger - Print message on how to attach debugger manually to
706: process and wait (-debugger_pause) seconds for attachment
707: . -malloc - Indicates use of PETSc error-checking malloc (on by default for debug version of libraries) (deprecated, use -malloc_debug)
708: . -malloc no - Indicates not to use error-checking malloc (deprecated, use -malloc_debug no)
709: . -malloc_debug - check for memory corruption at EVERY malloc or free, see PetscMallocSetDebug()
710: . -malloc_dump - prints a list of all unfreed memory at the end of the run
711: . -malloc_test - like -malloc_dump -malloc_debug, but only active for debugging builds, ignored in optimized build. May want to set in PETSC_OPTIONS environmental variable
712: . -malloc_view - show a list of all allocated memory during PetscFinalize()
713: . -malloc_view_threshold <t> - only list memory allocations of size greater than t with -malloc_view
714: . -fp_trap - Stops on floating point exceptions
715: . -no_signal_handler - Indicates not to trap error signals
716: . -shared_tmp - indicates /tmp directory is shared by all processors
717: . -not_shared_tmp - each processor has own /tmp
718: . -tmp - alternative name of /tmp directory
719: . -get_total_flops - returns total flops done by all processors
720: - -memory_view - Print memory usage at end of run
722: Options Database Keys for Profiling:
723: See Users-Manual: Chapter 13 Profiling for details.
724: + -info <optional filename> - Prints verbose information to the screen
725: . -info_exclude <null,vec,mat,pc,ksp,snes,ts> - Excludes some of the verbose messages
726: . -log_sync - Enable barrier synchronization for all events. This option is useful to debug imbalance within each event,
727: however it slows things down and gives a distorted view of the overall runtime.
728: . -log_trace [filename] - Print traces of all PETSc calls to the screen (useful to determine where a program
729: hangs without running in the debugger). See PetscLogTraceBegin().
730: . -log_view [:filename:format] - Prints summary of flop and timing information to screen or file, see PetscLogView().
731: . -log_view_memory - Includes in the summary from -log_view the memory used in each method, see PetscLogView().
732: . -log_summary [filename] - (Deprecated, use -log_view) Prints summary of flop and timing information to screen. If the filename is specified the
733: summary is written to the file. See PetscLogView().
734: . -log_exclude: <vec,mat,pc,ksp,snes> - excludes subset of object classes from logging
735: . -log_all [filename] - Logs extensive profiling information See PetscLogDump().
736: . -log [filename] - Logs basic profiline information See PetscLogDump().
737: . -log_mpe [filename] - Creates a logfile viewable by the utility Jumpshot (in MPICH distribution)
738: . -viewfromoptions on,off - Enable or disable XXXSetFromOptions() calls, for applications with many small solves turn this off
739: - -check_pointer_intensity 0,1,2 - if pointers are checked for validity (debug version only), using 0 will result in faster code
741: Only one of -log_trace, -log_view, -log_view, -log_all, -log, or -log_mpe may be used at a time
743: Options Database Keys for SAWs:
744: + -saws_port <portnumber> - port number to publish SAWs data, default is 8080
745: . -saws_port_auto_select - have SAWs select a new unique port number where it publishes the data, the URL is printed to the screen
746: this is useful when you are running many jobs that utilize SAWs at the same time
747: . -saws_log <filename> - save a log of all SAWs communication
748: . -saws_https <certificate file> - have SAWs use HTTPS instead of HTTP
749: - -saws_root <directory> - allow SAWs to have access to the given directory to search for requested resources and files
751: Environmental Variables:
752: + PETSC_TMP - alternative tmp directory
753: . PETSC_SHARED_TMP - tmp is shared by all processes
754: . PETSC_NOT_SHARED_TMP - each process has its own private tmp
755: . PETSC_VIEWER_SOCKET_PORT - socket number to use for socket viewer
756: - PETSC_VIEWER_SOCKET_MACHINE - machine to use for socket viewer to connect to
759: Level: beginner
761: Notes:
762: If for some reason you must call MPI_Init() separately, call
763: it before PetscInitialize().
765: Fortran Version:
766: In Fortran this routine has the format
767: $ call PetscInitialize(file,ierr)
769: + ierr - error return code
770: - file - [optional] PETSc database file, also checks ~username/.petscrc and .petscrc use PETSC_NULL_CHARACTER to not check for
771: code specific file. Use -skip_petscrc in the code specific file to skip the .petscrc files
773: Important Fortran Note:
774: In Fortran, you MUST use PETSC_NULL_CHARACTER to indicate a
775: null character string; you CANNOT just use NULL as
776: in the C version. See Users-Manual: Chapter 11 PETSc for Fortran Users for details.
778: If your main program is C but you call Fortran code that also uses PETSc you need to call PetscInitializeFortran() soon after
779: calling PetscInitialize().

794: The checking over compatible runtime libraries is complicated by the MPI ABI initiative

798: Intel� MPI Library v5.0 (2014)

800: As of July 31, 2017 the ABI number still appears to be 12, that is all of the versions
801: listed above and since that time are compatible.
803: Unfortunately the MPI ABI initiative has not defined a way to determine the ABI number
804: at compile time or runtime. Thus we will need to systematically track the allowed versions
805: and how they are represented in the mpi.h and MPI_Get_library_version() output in order
806: to perform the checking.
808: Currently we only check for pre MPI ABI versions (and packages that do not follow the MPI ABI).
810: Questions:
812: Should the checks for ABI incompatibility be only on the major version number below?
813: Presumably the output to stderr will be removed before a release.
