See PetscLogTraceBegin(). 668 . -log_view [:filename:format] - Prints summary of flop and timing information to screen or file, see PetscLogView(). 669 . -log_summary [filename] - (Deprecated, use -log_view) Prints summary of flop and timing information to screen. If the filename is specified the 670 summary is written to the file. See PetscLogView(). 671 . -log_exclude: <vec,mat,pc.ksp,snes> - excludes subset of object classes from logging 672 . -log_all [filename] - Logs extensive profiling information See PetscLogDump(). 673 . -log [filename] - Logs basic profiline information See PetscLogDump(). 674 . -log_mpe [filename] - Creates a logfile viewable by the utility Jumpshot (in MPICH distribution) 675 - -check_pointer_intensity 0,1,2 - if pointers are checked for validity (debug version only), using 0 will result in faster code 676 677 Only one of -log_trace, -log_view, -log_view, -log_all, -log, or -log_mpe may be used at a time 678 679 Options Database Keys for SAWs: 680 + -saws_port <portnumber> - port number to publish SAWs data, default is 8080 681 . -saws_port_auto_select - have SAWs select a new unique port number where it publishes the data, the URL is printed to the screen 682 this is useful when you are running many jobs that utilize SAWs at the same time 683 . -saws_log <filename> - save a log of all SAWs communication 684 . -saws_https <certificate file> - have SAWs use HTTPS instead of HTTP 685 - -saws_root <directory> - allow SAWs to have access to the given directory to search for requested resources and files 686 687 Environmental Variables: 688 + PETSC_TMP - alternative tmp directory 689 .
