[torqueusers] Node is not responding!

[Hakeem Almabrazi]

Steve,

Thank you for your tip.  That was the cause of my issue.  I had to start the server_sched daemon. I started looking at the Maui scheduler.  It looks like another big learning curve I need to do.

Again, I appreciate your help,

~Hak

I hope I will not waste anyone's time by asking such stupid question but I have tried to look for some answers in the archived listinfo but since there is no search capabilities built in I find it harder to find what I need.

What scheduler are you using above TORQUE ( PBS_SCHED, MAUI, etc)? If there is nothing that tells TORQUE to run the job, it won't run (unless you force it to run with qrun <jobid>). 

If everything is setup right with a scheduler and such, you should be able to submit a job interactively to run some basic tests, a la:    qsub -I -q batch ,etc,etc...

If you are using Maui/Moab as a scheduler, run a checkjob -v <nodeid> which will give you some information on why the scheduler isn't starting the job.

Here is a link to integrating TORQUE+MAUI [open source]:
http://www.adaptivecomputing.com/resources/docs/maui/pbsintegration.php

You should be able to use the base Maui setup with TORQUE.

Hope that helps.
