Use -skip_petscrc in the code specific file to skip the .petscrc files 576 - help - [optional] Help message to print, use NULL for no message 577 578 If you wish PETSc code to run ONLY on a subcommunicator of MPI_COMM_WORLD, create that 579 communicator first and assign it to PETSC_COMM_WORLD BEFORE calling PetscInitialize(). Thus if you are running a 580 four process job and two processes will run PETSc and have PetscInitialize() and PetscFinalize() and two process will not, 581 then do this. If ALL processes in the job are using PetscInitialize() and PetscFinalize() then you don't need to do this, even 582 if different subcommunicators of the job are doing different things with PETSc. 583 584 Options Database Keys: 585 + -start_in_debugger [noxterm,dbx,xdb,gdb,...] - Starts program in debugger 586 . -on_error_attach_debugger [noxterm,dbx,xdb,gdb,...] - Starts debugger when error detected 587 . -on_error_emacs <machinename> causes emacsclient to jump to error file 588 . -on_error_abort calls abort() when error detected (no traceback) 589 . -on_error_mpiabort calls MPI_abort() when error detected 590 . -error_output_stderr prints error messages to stderr instead of the default stdout 591 . -error_output_none does not print the error messages (but handles errors in the same way as if this was not called) 592 . -debugger_nodes [node1,node2,...] - Indicates nodes to start in debugger 593 . -debugger_pause [sleeptime] (in seconds) - Pauses debugger 594 . -stop_for_debugger - Print message on how to attach debugger manually to 595 process and wait (-debugger_pause) seconds for attachment 596 . -malloc - Indicates use of PETSc error-checking malloc (on by default for debug version of libraries) 597 . -malloc no - Indicates not to use error-checking malloc 598 . -malloc_debug - check for memory corruption at EVERY malloc or free 599 . -malloc_test - like -malloc_dump -malloc_debug, but only active for debugging builds 600 . -fp_trap - Stops on floating point exceptions (Note that on the 601 IBM RS6000 this slows code by at least a factor of 10.) 602 . -no_signal_handler - Indicates not to trap error signals 603 . -shared_tmp - indicates /tmp directory is shared by all processors 604 . -not_shared_tmp - each processor has own /tmp 605 . -tmp - alternative name of /tmp directory 606 . -get_total_flops - returns total flops done by all processors 607 . -memory_info - Print memory usage at end of run 608 - -server <port> - start PETSc webserver (default port is 8080) 609 610 Options Database Keys for Profiling: 611 See the <a href="../../docs/manual.pdf#nameddest=ch_profiling">profiling chapter of the users manual</a> for details. 612 + -info <optional filename> - Prints verbose information to the screen 613 . -info_exclude <null,vec,mat,pc,ksp,snes,ts> - Excludes some of the verbose messages 614 . -log_sync - Log the synchronization in scatters, inner products and norms 615 . -log_trace [filename] - Print traces of all PETSc calls to the screen (useful to determine where a program 616 hangs without running in the debugger). See PetscLogTraceBegin(). 617 . -log_summary [filename] - Prints summary of flop and timing information to screen. If the filename is specified the 618 summary is written to the file. See PetscLogView(). 619 . -log_summary_python [filename] - Prints data on of flop and timing usage to a file or screen. See PetscLogPrintSViewPython(). 620 . -log_all [filename] - Logs extensive profiling information See PetscLogDump(). 621 . -log [filename] - Logs basic profiline information See PetscLogDump(). 622 - -log_mpe [filename] - Creates a logfile viewable by the utility Jumpshot (in MPICH distribution) 623 624 Only one of -log_trace, -log_summary, -log_all, -log, or -log_mpe may be used at a time 625 626 Environmental Variables: 627 + PETSC_TMP - alternative tmp directory 628 . PETSC_SHARED_TMP - tmp is shared by all processes 629 . PETSC_NOT_SHARED_TMP - each process has its own private tmp 630 .
