May want to set in PETSC_OPTIONS environmental variable 702 . -malloc_view - show a list of all allocated memory during PetscFinalize() 703 . -malloc_view_threshold <t> - only list memory allocations of size greater than t with -malloc_view 704 . -fp_trap - Stops on floating point exceptions 705 . -no_signal_handler - Indicates not to trap error signals 706 . -shared_tmp - indicates /tmp directory is shared by all processors 707 . -not_shared_tmp - each processor has own /tmp 708 . -tmp - alternative name of /tmp directory 709 . -get_total_flops - returns total flops done by all processors 710 - -memory_view - Print memory usage at end of run 711 712 Options Database Keys for Profiling: 713 See Users-Manual: ch_profiling for details. 714 + -info <optional filename> - Prints verbose information to the screen 715 . -info_exclude <null,vec,mat,pc,ksp,snes,ts> - Excludes some of the verbose messages 716 . -log_sync - Enable barrier synchronization for all events. This option is useful to debug imbalance within each event, 717 however it slows things down and gives a distorted view of the overall runtime. 718 . -log_trace [filename] - Print traces of all PETSc calls to the screen (useful to determine where a program 719 hangs without running in the debugger). See PetscLogTraceBegin(). 720 . -log_view [:filename:format] - Prints summary of flop and timing information to screen or file, see PetscLogView(). 721 . -log_view_memory - Includes in the summary from -log_view the memory used in each method, see PetscLogView(). 722 . -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 744 . PETSC_NOT_SHARED_TMP - each process has its own private tmp 745 .
