Hi,
I have a program that runs two threads in stead of two processes. I want to use pipe to redirect the output of the first thread to the input of the second thread.
One thread is continuously writing to a pipe, and the other thread will read from the pipe.
How do I do that?

I can use pipe output to a file. For example
./somescript.sh > output.txt
But for example if the output from ./somescript.sh is slow. like if it prints one line every minute then output.txt is not updated every minute. Lines are written to output.txt in one go, hence have to wait for the whole... (2 Replies)

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
