Thanks for the reply. The input I have is just a very simple CSV that I grabbed for testing. A sample:

Code:
00102,20150501,0001,0,CLR, ,10.00, , , ,24, ,-4.4, ,23, ,-4.9, ,21, ,-6.1, , 88, , 0, ,000, , , ,29.70, , , , , ,30.01, ,AA, , , ,29.88, 
00102,20150501,0101,0,CLR, ,10.00, , , ,22, ,-5.6, ,21, ,-6.0, ,19, ,-7.2, , 88, , 0, ,000, , , ,29.71, , , , , ,30.02, ,AA, , , ,29.89, 
00102,20150501,0201,0,CLR, ,10.00, , , ,19, ,-7.2, ,18, ,-7.5, ,17, ,-8.3, , 92, , 0, ,000, , , ,29.72, , , , , ,30.03, ,AA, , , ,29.90,


The processor scripts that are called by the distributor just go through every field of every line, and if the field contains a positive integer it sums it.

Code:
    {
    for (i = 1; i <= NF; i++)
        {
        if ($i ~ /^[0-9]+$/)
            {
            SUM += $i
            }
        }
    }
END {
    printf "%.0f\n",  SUM
    }

It's a weird, arbitrary task, I know. Its only purpose is to test the distributor/processor idea. The distributor that calls the script above is already posted. Its output looks like:

25280650967054
25280650651146
25280650873710
25280650942866
25280650844079
25280650677879
25280671120373

Each is simply the output from each of, in this case, the 7 processor scripts that were called. So, I would get that as the output of:

Code:
mawk -F , -v count=7 'NR > 1 {mod = NR%count + 1 ; proc = "./proc." mod ".mawk -F ,"; print $0 | proc}' datafile.csv

Currently, I pipe that to:

Code:
awk '{SUM += $1} END {print SUM}'

I'd like to eliminate that pipe and have the distributor receive back each processor's results and sum them itself. It might not be readily doable, but I figured someone here might have an idea. Thank you.

irsend

IRSEND(1)								FSF								 IRSEND(1)

NAME

       irsend - basic LIRC program to send infra-red commands

SYNOPSIS

       irsend [options] DIRECTIVE REMOTE CODE [CODE...]

DESCRIPTION

       Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such
       as TV boxes, HiFi sets, etc.

       DIRECTIVE can be:
	  SEND_ONCE	    - send CODE [CODE ...] once
	  SEND_START	    - start repeating CODE
	  SEND_STOP	    - stop repeating CODE
	  LIST		    - list configured remote items
	  SET_TRANSMITTERS  - set transmitters NUM [NUM ...]
	  SIMULATE	    - simulate IR event

       REMOTE is the name of a remote, as described in the lircd configuration file.

       CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file.

       NUM is the transmitter number of the hardware device.

       For the LIST DIRECTIVE, REMOTE and/or CODE can be empty:

	  LIST	 ""    ""   - list all configured remote names
	  LIST REMOTE  ""   - list all codes of REMOTE
	  LIST REMOTE CODE  - list only CODE of REMOTE

       The SIMULATE command only works if it has been explicitly enabled in lircd.

       -h --help
	      display usage summary

       -v --version
	      display version

       -d --device
	      use given lircd socket [/var/run/lirc/lircd]

       -a --address=host[:port]
	      connect to lircd at this address

       -# --count=n
	      send command n times

EXAMPLES

	  irsend LIST DenonTuner ""
	  irsend SEND_ONCE  DenonTuner PROG-SCAN
	  irsend SEND_ONCE  OnkyoAmpli VOL-UP VOL-UP VOL-UP VOL-UP
	  irsend SEND_START OnkyoAmpli VOL-DOWN ; sleep 3
	  irsend SEND_STOP  OnkyoAmpli VOL-DOWN
	  irsend SET_TRANSMITTERS 1
	  irsend SET_TRANSMITTERS 1 3 4
	  irsend SIMULATE "0000000000000476 00 OK TECHNISAT_ST3004S"

FILES

       /etc/lirc/lircd.conf
	      Default lircd configuration file.  It should contain all the remotes, their infra-red codes and the corresponding timing	and  wave-
	      form details.

DIAGNOSTICS

       If lircd is not running (or /var/run/lirc/lircd lacks write permissions) irsend aborts with the following diagnostics:
       "irsend: could not connect to socket"
       "irsend: Connection refused" (or "Permission denied").

SEE ALSO

       The documentation for lirc is maintained as html pages. They are located under html/ in the documentation directory.
