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.
