The man page is simply out of date - see https://github.com/open-mpi/ompi/issues/7095 for further thinking

Long question: I am used to that the option --output-filename file.out will generate the files file.out.0 file.out.1 etc. The default logic switched to file.out/1/rank.*/stdout man mpirun gives me: -output-filename, --output-filename <filename> Redirect the stdout, stderr, and stddiag of all processes to a process-unique version of the specified filename. ... mpirun --help output gives me: -output-filename|--output-filename <arg0> Redirect output from application processes into filename/job/rank/std[out,err,diag]. A relative path value will be converted to an absolute path So man is reporting a wrong logic, help provides the correct answer for the logic. A lock in the code yields that the output from man comes from ./orte/orted/orted_main.c: { "orte_output_filename", '\0', "output-filename", "output-filename", 1, NULL, OPAL_CMD_LINE_TYPE_STRING, "Redirect output from application processes into filename.rank" }, The mpirun output comes from ./orte/mca/schizo/ompi/schizo_ompi.c { "orte_output_filename", '\0', "output-filename", "output-filename", 1, &orte_cmd_options.output_filename, OPAL_CMD_LINE_TYPE_STRING, "Redirect output from application processes into filename/job/rank/std[out,err,diag]. A relative path value will be converted to an absolute path", OPAL_CMD_LINE_OTYPE_OUTPUT }, These two behaviors can probably be selected with some mca parameters, but I could not figure out which one. So the final question: How can I configure which default backend is used for the command line parameter --output-filename?
