See PetscLogTraceBegin(). 661 . -log_view [:filename:format] - Prints summary of flop and timing information to screen or file, see PetscLogView(). 662 . -log_summary [filename] - (Deprecated, use -log_view) Prints summary of flop and timing information to screen. If the filename is specified the 663 summary is written to the file. See PetscLogView(). 664 . -log_exclude: <vec,mat,pc.ksp,snes> - excludes subset of object classes from logging 665 . -log_all [filename] - Logs extensive profiling information See PetscLogDump(). 666 . -log [filename] - Logs basic profiline information See PetscLogDump(). 667 - -log_mpe [filename] - Creates a logfile viewable by the utility Jumpshot (in MPICH distribution) 668 669 Only one of -log_trace, -log_view, -log_view, -log_all, -log, or -log_mpe may be used at a time 670 671 Options Database Keys for SAWs: 672 + -saws_port <portnumber> - port number to publish SAWs data, default is 8080 673 . -saws_port_auto_select - have SAWs select a new unique port number where it publishes the data, the URL is printed to the screen 674 this is useful when you are running many jobs that utilize SAWs at the same time 675 . -saws_log <filename> - save a log of all SAWs communication 676 . -saws_https <certificate file> - have SAWs use HTTPS instead of HTTP 677 - -saws_root <directory> - allow SAWs to have access to the given directory to search for requested resources and files 678 679 Environmental Variables: 680 + PETSC_TMP - alternative tmp directory 681 . PETSC_SHARED_TMP - tmp is shared by all processes 682 . PETSC_NOT_SHARED_TMP - each process has its own private tmp 683 . PETSC_VIEWER_SOCKET_PORT - socket number to use for socket viewer 684 - PETSC_VIEWER_SOCKET_MACHINE - machine to use for socket viewer to connect to 685 686 687 Level: beginner 688 689 Notes: 690 If for some reason you must call MPI_Init() separately, call 691 it before PetscInitialize(). 692 693 Fortran Version: 694 In Fortran this routine has the format 695 $ call PetscInitialize(file,ierr) 696 697 + ierr - error return code 698 - file - [optional] PETSc database file, also checks ~username/.petscrc and .petscrc use PETSC_NULL_CHARACTER to not check for 699 code specific file.
