Q:

SGE submitted job doesn't run

I'm using Sun Grid Engine on my ubuntu 14.04 to queue my jobs to be run on my multicore CPU.
I've installed and set up SGE on my system but I have problem when testing it. I've created a "hello_world" dir which contains two shell scripts named "hello_world.sh" & "hello_world_qsub.sh" first including a simple command and second including qsub command to submit the first script file as a job to be run. 
Here's what "hello_world.sh" includes:
#!/bin/bash

echo "Hello world" > /home/theodore/tmp/hello_world/hello_world_output.txt

And here's what "hello_world_qsub.sh" includes:
#!/bin/bash

qsub \
  -e /home/hello_world/hello_world_qsub.error \
  -o /home/hello_world/hello_world_qsub.log \
  ./hello_world.sh

after giving permission to the second sh file and running it with "./hello_world_qsub.sh" command from the specified dir, the output is reasonable:
Your job 1 ("hello_world.sh") has been submitted

But the output of "qstat" command is frustrating:
    job-ID  prior   name       user         state submit/start at     queue                          slots ja-task-ID

And the "state" column always remain on "qw" and never changes to "r".
Here's the output of "qstat -j 1" command:

                        All queues dropped because of overload or full

And here's the output of "qhost" command:
HOSTNAME                ARCH         NCPU  LOAD  MEMTOT  MEMUSE  SWAPTO  SWAPUS
-------------------------------------------------------------------------------

What should I do to make my jobs run and finish their task?

A:

From your qhost output, it looks like your machine "localhost" is properly configured in SGE. However, on "localhost" sge_execd is either not running or not configured properly. If it were, qhost would report statistics for "localhost".
