See PetscLogTraceBegin(). 660 . -log_view [:filename:format] - Prints summary of flop and timing information to screen or file, see PetscLogView(). 661 . -log_summary [filename] - (Deprecated, use -log_view) Prints summary of flop and timing information to screen. If the filename is specified the 662 summary is written to the file. See PetscLogView(). 663 . -log_exclude: <vec,mat,pc.ksp,snes> - excludes subset of object classes from logging 664 . -log_all [filename] - Logs extensive profiling information See PetscLogDump(). 665 . -log [filename] - Logs basic profiline information See PetscLogDump(). 666 - -log_mpe [filename] - Creates a logfile viewable by the utility Jumpshot (in MPICH distribution) 667 668 Only one of -log_trace, -log_view, -log_view, -log_all, -log, or -log_mpe may be used at a time 669 670 Options Database Keys for SAWs: 671 + -saws_port <portnumber> - port number to publish SAWs data, default is 8080 672 . -saws_port_auto_select - have SAWs select a new unique port number where it publishes the data, the URL is printed to the screen 673 this is useful when you are running many jobs that utilize SAWs at the same time 674 . -saws_log <filename> - save a log of all SAWs communication 675 . -saws_https <certificate file> - have SAWs use HTTPS instead of HTTP 676 - -saws_root <directory> - allow SAWs to have access to the given directory to search for requested resources and files 677 678 Environmental Variables: 679 + PETSC_TMP - alternative tmp directory 680 . PETSC_SHARED_TMP - tmp is shared by all processes 681 . PETSC_NOT_SHARED_TMP - each process has its own private tmp 682 .
