# number of processes to start
- -wdir <dirname>
# working directory to start in

# place to look for executables
- -host <hostname>
# host to start on
- -soft <spec>
# modifier of -n value
- -arch <arch>
# arch type to start on (not implemented)
- -envall
# pass all env vars in current environment
- -envnone
# pass no env vars -envlist <list of env var names> # pass current values of these vars
- -env <name> <value>
# pass this value of this env var mpiexec [global args] [local args] executable args : [local args] executable...
- mpiexec -gdba jobid
- # gdb-attach to existing jobid
- mpiexec -configfile filename

FUNCTIONS
adjust_nprocs(nProcs, softness)
collect_args(args, localArgSets)
- ctime(...) ctime(seconds) -> string
- Convert a time in seconds since the Epoch to a string in local time. This is equivalent to asctime(localtime(seconds)). When the time tuple is not present, current time as returned by localtime() is used.
- format_sorted_ranks(ranks)
- get_parms_from_xml_file(msgToMPD)
- get_vals_for_attach(parmdb, conSock, msgToMPD)
- handle_cli_stderr_input(sock, streamHandler)
- handle_cli_stdout_input(sock, parmdb, streamHandler, linesPerRank)
- handle_local_argset(argset, machineFileInfo, msgToMPD)
- handle_man_input(sock, streamHandler)
- handle_sig_occurred(manSock)
- handle_stdin_input(stdin_stream, parmdb, streamHandler, manSock)
# NOTE: stdin is supposed to be slow, low-volume.We read it all here (as it- # appears on the fd) and send it immediately to the receivers.
If the user # redirects a "large" file (perhaps as small as 5k) into us, we will send it
- # all out right away.
This can cause things to hang on the remote (recvr) side. # We do not wait to read here until the recvrs read because there may be several # recvrs and they may read at different speeds/times.
- mpiexec()
- print_ready_merged_lines(minRanks, parmdb, linesPerRank)
- read_machinefile(machineFilename)
- sig_handler(signum, frame)
- time(...) time() -> floating point number
Return the current time in seconds since the Epoch. Fractions of a second may be present if the system clock provides them.- usage()
