Hi!
The best idea (what I can imagine) is to get GNU Parallel. Especially for 16-core monsters. Smilie I played with it a little - it's easy to use and you can say it how many jobs it should execute. But no one of my boxes have more than 2 cores (((.
Code:
find . -name '*.txt' | parallel -j4 ./prog

It works (here) as xargs.
And don't confuse GNU parallel with parallel from "moreutils".

No, you definitely don't have it - it's too fresh. You should compile it. But it has not to have root privileges and you can install it in your $HOME/bin. The link - GNU Parallel - GNU Project - Free Software Foundation

But I really used 0install (for debian based, ubuntu in my case):
Code:
sudo apt-get install zeroinstall-injector
0alias parallel http://git.savannah.gnu.org/cgit/parallel.git/plain/packager/0install/parallel.xml

thanks, yazu.
Do you have any idea regarding following error message:
Code:
/bin/sh: ./sem: Permission denied

I'm not a root. Just an user to install it.

Ok. I don't understand at once that this question about parallel. I'll look at it.

---------- Post updated at 06:50 PM ---------- Previous update was at 06:42 PM ----------

Well I downloaded the latest tarball, and (not as root, of course) :
Code:
./configure --prefix=$HOME/opt
make 
make install
PATH=$HOME/opt/bin:$PATH
parallel --version
  GNU parallel 20110822

Code:
seq 1 5 | parallel -j5 echo
1
2
4
3
5

Do not see any problems.
