Use -skip_petscrc in the code specific file to skip the .petscrc files 575 - help - [optional] Help message to print, use NULL for no message 576 577 If you wish PETSc code to run ONLY on a subcommunicator of MPI_COMM_WORLD, create that 578 communicator first and assign it to PETSC_COMM_WORLD BEFORE calling PetscInitialize(). Thus if you are running a 579 four process job and two processes will run PETSc and have PetscInitialize() and PetscFinalize() and two process will not, 580 then do this. If ALL processes in the job are using PetscInitialize() and PetscFinalize() then you don't need to do this, even 581 if different subcommunicators of the job are doing different things with PETSc. 582 583 Options Database Keys: 584 + -start_in_debugger [noxterm,dbx,xdb,gdb,...] - Starts program in debugger 585 . -on_error_attach_debugger [noxterm,dbx,xdb,gdb,...] - Starts debugger when error detected 586 . -on_error_emacs <machinename> causes emacsclient to jump to error file 587 . -on_error_abort calls abort() when error detected (no traceback) 588 . -on_error_mpiabort calls MPI_abort() when error detected 589 . -error_output_stderr prints error messages to stderr instead of the default stdout 590 . -error_output_none does not print the error messages (but handles errors in the same way as if this was not called) 591 . -debugger_nodes [node1,node2,...] - Indicates nodes to start in debugger 592 . -debugger_pause [sleeptime] (in seconds) - Pauses debugger 593 . -stop_for_debugger - Print message on how to attach debugger manually to 594 process and wait (-debugger_pause) seconds for attachment 595 . -malloc - Indicates use of PETSc error-checking malloc (on by default for debug version of libraries) 596 . -malloc no - Indicates not to use error-checking malloc 597 . -malloc_debug - check for memory corruption at EVERY malloc or free 598 . -malloc_test - like -malloc_dump -malloc_debug, but only active for debugging builds 599 . -fp_trap - Stops on floating point exceptions (Note that on the 600 IBM RS6000 this slows code by at least a factor of 10.) 601 . -no_signal_handler - Indicates not to trap error signals 602 . -shared_tmp - indicates /tmp directory is shared by all processors 603 . -not_shared_tmp - each processor has own /tmp 604 . -tmp - alternative name of /tmp directory 605 . -get_total_flops - returns total flops done by all processors 606 . -memory_info - Print memory usage at end of run 607 - -server <port> - start PETSc webserver (default port is 8080) 608 609 Options Database Keys for Profiling: 610 See the <a href="../../docs/manual.pdf#nameddest=ch_profiling">profiling chapter of the users manual</a> for details. 611 + -info <optional filename> - Prints verbose information to the screen 612 . -info_exclude <null,vec,mat,pc,ksp,snes,ts> - Excludes some of the verbose messages 613 . -log_sync - Log the synchronization in scatters, inner products and norms 614 . -log_trace [filename] - Print traces of all PETSc calls to the screen (useful to determine where a program 615 hangs without running in the debugger).
