General Unix job-scheduling discussion

[pinhodecarlos]

Under linux.
Inside ecm folder I have 8 folders called cl1 to cl8.
Will this script work? Will ecmclient run hidden, not with terminal open?

#!/bin/sh
for i in 1 2 3 4 5 6 7 8
  do
    cd cl${i}
    ./ecmclient
    cd ..
  done

Is the server down?

Edit: It is down. Email sent to Paul.

Actually, it is up and has been fo some time. The problem is that my ISP is amazingly flaky today. Mail back to Carlos is still waiting to be sent on by the ISP's mail server and I'm typing this in a brief window of activity. Let's hope the net stays up long enough for posting.

Thank you Paul. I see the server up and running but I still didn't get your email but that is not important.
Added four cores, more four within a week. The problem was when I fired up the fourth core it was night here so I forgot to check if the server was online. When I woke up I noticed the server was down, this core was idle, but the others were in cycle loop trying to connect the server every time a curve was completed within one minute pause between client-server connection.

Hope this can help others or me to find factors quickly.

Can you check if I got right that script?

[pinhodecarlos]

Found a factor but didn't get the email notification.

Better: use screen and run each instance in its own terminal. Then you can detach screen, and everything keeps running in the background. when you reattach, you get all terminals back.

Even better: use byobu (fancy wrapper around screen or - which I prefer - tmux)

Here's the problem. I use Putty under windows to connect to the linux servers and therefore I can't detach screen. What I usually do is to shutdown putty after I start an application. I repeat this process as many times I want to start any instance of ecm (10 times).

You should be able to detach (and resume) your session.

We do this all of the time with Putty.

[pinhodecarlos]

Thank you both. I will take a look on those (cycle and detach thing).
I think it is better to move this conversation to other place because we are hijacking Paul's thread.

Blip, I tried your script and didn't work. Must be something on the setup of Putty or something related with permission to the server.

I have another question related to linux.
Having only access to a linux machine through terminal, no GUI, how do I download the files from NFS@Home with password? This machine is dedicated to run LLR and from time to time some post-processing jobs for NFS@Home.
What I usually do is to download the files from my windows computer work and then upload them to the server but this upload is limited to 1MB/s so it is quite boring. The set of files are always something like:

W_2_786.dat.gz
W_2_786.ini
W_2_786.fb

Thank you in advance,

Carlos
