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