See PetscLogTraceBegin(). 669 . -log_view [:filename:format] - Prints summary of flop and timing information to screen or file, see PetscLogView(). 670 . -log_summary [filename] - (Deprecated, use -log_view) Prints summary of flop and timing information to screen. If the filename is specified the 671 summary is written to the file. See PetscLogView(). 672 . -log_exclude: <vec,mat,pc.ksp,snes> - excludes subset of object classes from logging 673 . -log_all [filename] - Logs extensive profiling information See PetscLogDump(). 674 . -log [filename] - Logs basic profiline information See PetscLogDump(). 675 . -log_mpe [filename] - Creates a logfile viewable by the utility Jumpshot (in MPICH distribution) 676 - -check_pointer_intensity 0,1,2 - if pointers are checked for validity (debug version only), using 0 will result in faster code 677 678 Only one of -log_trace, -log_view, -log_view, -log_all, -log, or -log_mpe may be used at a time 679 680 Options Database Keys for SAWs: 681 + -saws_port <portnumber> - port number to publish SAWs data, default is 8080 682 . -saws_port_auto_select - have SAWs select a new unique port number where it publishes the data, the URL is printed to the screen 683 this is useful when you are running many jobs that utilize SAWs at the same time 684 . -saws_log <filename> - save a log of all SAWs communication 685 . -saws_https <certificate file> - have SAWs use HTTPS instead of HTTP 686 - -saws_root <directory> - allow SAWs to have access to the given directory to search for requested resources and files 687 688 Environmental Variables: 689 + PETSC_TMP - alternative tmp directory 690 .
