See PetscInfo(). 732 . -log_sync - Enable barrier synchronization for all events. This option is useful to debug imbalance within each event, 733 however it slows things down and gives a distorted view of the overall runtime. 734 . -log_trace [filename] - Print traces of all PETSc calls to the screen (useful to determine where a program 735 hangs without running in the debugger). See PetscLogTraceBegin(). 736 . -log_view [:filename:format] - Prints summary of flop and timing information to screen or file, see PetscLogView(). 737 . -log_view_memory - Includes in the summary from -log_view the memory used in each method, see PetscLogView(). 738 . -log_summary [filename] - (Deprecated, use -log_view) Prints summary of flop and timing information to screen.

PETSC_SHARED_TMP - tmp is shared by all processes 760 . PETSC_NOT_SHARED_TMP - each process has its own private tmp 761 . PETSC_OPTIONS - a string containing additional options for petsc in the form of command line "-key value" pairs 762 .
