See PetscInfo(). 707 . -log_sync - Enable barrier synchronization for all events. This option is useful to debug imbalance within each event, 708 however it slows things down and gives a distorted view of the overall runtime. 709 . -log_trace [filename] - Print traces of all PETSc calls to the screen (useful to determine where a program 710 hangs without running in the debugger). See PetscLogTraceBegin(). 711 . -log_view [:filename:format] - Prints summary of flop and timing information to screen or file, see PetscLogView(). 712 . -log_view_memory - Includes in the summary from -log_view the memory used in each method, see PetscLogView(). 713 . -log_summary [filename] - (Deprecated, use -log_view) Prints summary of flop and timing information to screen.
