Re: [1/2OT] the stat 'D'
I am new to the xargs, so I don't know how to let it run in background. The waiting is going to kill me, I mean so slow. Thanks ahead for your suggestions, No idea about what is xargs, but I guess that simply calling your script from a console with a '' at end of command will be ok, aka $myscript.sh -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

I use something like
echo1
2 idx.txt
for i in `seq w 1 1 16`
do
cal_dist -i $i.in -o $i.out idx.txt
done
The xargs alternative is something like:
$ seq -w 1 1 16 | xargs -n 1 -P 8 -I A cal_dist ../../dist_A.out
But there is a problem, I need to select the idx.txt, namely pick 1
2 in prompt during the running of cal_dist, but I am a bit stuck with
this.

This is not a valid call of seq, you probably meant `seq -w 1 1 16`
instead.
do
cal_dist -i $i.in -o $i.out idx.txt
done
I have no idea what cal_dist is or does, but the processes are in state
uninterruptible sleep (that's what D stands for), i.e. they are
waiting for system calls to complete. Typically the only syscalls that
take any noticeable time are related to I/O, so most likely the
processes are waiting for your hard disk to deliver data from the $i.in
files. Or they are doing lots of fsync(2) calls on the $i.out files
which can cause a dramatic slowdown on some filesystems.
Cheers,
Sven

Last night I spent some time to check the D stat.
It's kinda of tricky, why my intuition tells me that those jobs run in
foreground, not background, won't have such problem.
Perhaps that's why I wish to run in foreground, I am not so familiar
with make j in this situation, neither familiar with the xargs.

Sven

In particular, users are asked to run only one background job at a time. from http://www.washington.edu/computing/unix/background.html now I know why there are so many D for those background jobs. if I am wrong, please let me know, Thanks, -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.
