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 .
