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.



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_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.


print_ready_merged_lines(minRanks, parmdb, linesPerRank)


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.
