See PetscLogTraceBegin(). 666 . -log_view [:filename:format] - Prints summary of flop and timing information to screen or file, see PetscLogView(). 667 . -log_summary [filename] - (Deprecated, use -log_view) Prints summary of flop and timing information to screen. If the filename is specified the 668 summary is written to the file. See PetscLogView(). 669 . -log_exclude: <vec,mat,pc.ksp,snes> - excludes subset of object classes from logging 670 . -log_all [filename] - Logs extensive profiling information See PetscLogDump(). 671 . -log [filename] - Logs basic profiline information See PetscLogDump(). 672 - -log_mpe [filename] - Creates a logfile viewable by the utility Jumpshot (in MPICH distribution) 673 674 Only one of -log_trace, -log_view, -log_view, -log_all, -log, or -log_mpe may be used at a time 675 676 Options Database Keys for SAWs: 677 + -saws_port <portnumber> - port number to publish SAWs data, default is 8080 678 . -saws_port_auto_select - have SAWs select a new unique port number where it publishes the data, the URL is printed to the screen 679 this is useful when you are running many jobs that utilize SAWs at the same time 680 . -saws_log <filename> - save a log of all SAWs communication 681 . -saws_https <certificate file> - have SAWs use HTTPS instead of HTTP 682 - -saws_root <directory> - allow SAWs to have access to the given directory to search for requested resources and files 683 684 Environmental Variables: 685 + PETSC_TMP - alternative tmp directory 686 . PETSC_SHARED_TMP - tmp is shared by all processes 687 . PETSC_NOT_SHARED_TMP - each process has its own private tmp 688 .
