Hi,
start your program in the background and protect it from the HUP-signal, which causes it to stop when you close your connection to the remote machine.
This will of course only work for non-interactive programs.
Edit: in case your program needs human interaction have a look if the tool screen is installed on the remote machine.
Hi Everyone,
Good day.

Hi,
Have anyone seen this problem, there is one remote side where their ftp connection to our server will always fail with connection closed by remote host and the second connection will be working.
is this an OS issue or network issue?
Thanks

Hi everyone,
I am hoping anyone of you could help me in this weird problem we have in 1 of our Solaris 10 servers. Lately, we have been having some ftp problems in this server. Though it can ping any server within the network, it seems that it can only ftp to a select few. For most servers, the... (4 Replies)

Hello there.
I'm fairly new to Linux, but I am connecting via SSH and PuTTY to a remote server, and I am running a fairly heavy MySQL script in a PHP page.
Our connection here is dodgy to say the least and I get continuous disconnections.
My question is, when I get disconnected, does my... (4 Replies)

CD-HIT-PARA.PL(1) User Commands CD-HIT-PARA.PL(1)NAME
cd-hit-para.pl - divide a big clustering job into pieces to run cd-hit or cd-hit-est jobs
SYNOPSIS
cd-hit-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 or cd-hit-est.
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 cd-hit-2d cd-hit-est 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 in fasta format, required
-o output filename, required
--P program, "cd-hit" or "cd-hit-est", default "cd-hit"
--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 input DB into, default 64
--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/cd-hit-est options can be speicified in command line
