This option is useful to debug imbalance within each event, 711 however it slows things down and gives a distorted view of the overall runtime. 712 . -log_trace [filename] - Print traces of all PETSc calls to the screen (useful to determine where a program 713 hangs without running in the debugger). See PetscLogTraceBegin(). 714 . -log_view [:filename:format] - Prints summary of flop and timing information to screen or file, see PetscLogView(). 715 . -log_summary [filename] - (Deprecated, use -log_view) Prints summary of flop and timing information to screen. If the filename is specified the 716 summary is written to the file. See PetscLogView(). 717 . -log_exclude: <vec,mat,pc,ksp,snes> - excludes subset of object classes from logging 718 . -log_all [filename] - Logs extensive profiling information See PetscLogDump(). 719 . -log [filename] - Logs basic profiline information See PetscLogDump(). 720 . -log_mpe [filename] - Creates a logfile viewable by the utility Jumpshot (in MPICH distribution) 721 . -viewfromoptions on,off - Enable or disable XXXSetFromOptions() calls, for applications with many small solves turn this off 722 - -check_pointer_intensity 0,1,2 - if pointers are checked for validity (debug version only), using 0 will result in faster code 723 724 Only one of -log_trace, -log_view, -log_view, -log_all, -log, or -log_mpe may be used at a time 725 726 Options Database Keys for SAWs: 727 + -saws_port <portnumber> - port number to publish SAWs data, default is 8080 728 . -saws_port_auto_select - have SAWs select a new unique port number where it publishes the data, the URL is printed to the screen 729 this is useful when you are running many jobs that utilize SAWs at the same time 730 . -saws_log <filename> - save a log of all SAWs communication 731 . -saws_https <certificate file> - have SAWs use HTTPS instead of HTTP 732 - -saws_root <directory> - allow SAWs to have access to the given directory to search for requested resources and files 733 734 Environmental Variables: 735 + PETSC_TMP - alternative tmp directory 736 . PETSC_SHARED_TMP - tmp is shared by all processes 737 . PETSC_NOT_SHARED_TMP - each process has its own private tmp 738 .
