You may want to reconsider

Since you did not specify what you are trying to monitor, I wanted to think of this differently...
There are 600 computers you want to analyze. So, if it take 60 seconds to connect, execute remote commands, transmit results file back, do something (on master computer), and then go to next remote computer.
That would mean ten hours, start to finish, if done sequentially. I suppose you could write something to do some in parallel?

Which brings me back to my initial premise...that this may not be possible based on the number of remote computers to analyze.

In human terms...
(a) you call 600 people to find out if they are coming for dinner
(b) receive emails of those who cannot attend

Probably easier to process the (b) list. Likewise, easier to process error files from remote computers.

NAME
cd-hit-2d-para.pl - divide a big clustering job into pieces to run cd-hit-2d or cd-hit-est-2d jobs SYNOPSIS
cd-hit-2d-para.pl options DESCRIPTION
This script divide a big clustering job into pieces and submit jobs to remote computers over a network to make it parallel. After all the jobs finished, the script merge the clustering results as if you just run a single cd-hit-2d or cd-hit-est-2d. You can also use it to divide big jobs on a single computer if your computer does not have enough RAM (with -L option). Requirements: 1 When run this script over a network, the directory where you run the scripts and the input files must be available on all the remote hosts with identical path. 2 If you choose "ssh" to submit jobs, you have to have passwordless ssh to any remote host, see ssh manual to know how to set up passwordless ssh. 3 I suggest to use queuing system instead of ssh, I currently support PBS and SGE 4 cd-hit-2d cd-hit-est-2d cd-hit-div cd-hit-div.pl must be in same directory where this script is in. Options -i input filename for 1st db in fasta format, required -i2 input filename for 2nd db in fasta format, required -o output filename, required --P program, "cd-hit-2d" or "cd-hit-est-2d", default "cd-hit-2d" --B filename of list of hosts, requred unless -Q or -L option is supplied --L number of cpus on local computer, default 0 when you are not running it over a cluster, you can use this option to divide a big clustering jobs into small pieces, I suggest you just use "--L 1" unless you have enough RAM for each cpu --S Number of segments to split 1st db into, default 2 --S2 Number of segments to split 2nd db into, default 8 --Q number of jobs to submit to queue queuing system, default 0 by default, the program use ssh mode to submit remote jobs --T type of queuing system, "PBS", "SGE" are supported, default PBS --R restart file, used after a crash of run -h print this help More cd-hit-2d/cd-hit-est-2d options can be speicified in command line Questions, bugs, contact Weizhong Li at liwz@sdsc.edu cd-hit-2d-para.pl 4.6-2012-04-25 April 2012 CD-HIT-2D-PARA.PL(1)
