This option is useful to debug imbalance within each event, 722 however it slows things down and gives a distorted view of the overall runtime. 723 . -log_trace [filename] - Print traces of all PETSc calls to the screen (useful to determine where a program 724 hangs without running in the debugger). See PetscLogTraceBegin(). 725 . -log_view [:filename:format] - Prints summary of flop and timing information to screen or file, see PetscLogView(). 726 . -log_view_memory - Includes in the summary from -log_view the memory used in each method, see PetscLogView(). 727 . -log_summary [filename] - (Deprecated, use -log_view) Prints summary of flop and timing information to screen.
