+Job status descriptions in squeue
+=================================
+
+When you run ``squeue`` (probably limiting the output with ``squeue -u <user_name>``), you will get a list of all jobs currently running or waiting to start. Most of the columns should be self-explaining, but the *ST* and *NODELIST (REASON)* columns can be confusing.
+
+*ST* stands for *state*. The most important states are listed below. For a more comprehensive list, check the `squeue help page section Job State Codes <https://slurm.schedmd.com/squeue.html#lbAG>`_.
+
+R
+  The job is running
+PD
+  The job is pending (i.e. waiting to run)
+CG
+  The job is completing, meaning that it will be finished soon
+
+The column *NODELIST (REASON)* will show you a list of computing nodes the job is running on if the job is actually running. If the job is pending, the column will give you a reason why it still pending. The most important reasons are listed below. For a more comprehensive list, check the `squeue help page section Job Reason Codes <https://slurm.schedmd.com/squeue.html#lbAF>`_.
+
+Priority
+  There is another pending job with higher priority
+Resources
+  The job has the highest priority, but is waiting for some running job to finish.
+QOS*Limit
+  This should only happen if you run your job with ``--qos=devel``. In developer mode you may only have one single job in the queue.
+launch failed requeued held
+  Job launch failed for some reason. This is normally due to a faulty node. Please contact us via support-uit@notur.no stating the problem, your user name, and the jobid(s).
+Dependency
+  Job cannot start before some other job is finished. This should only happen if you started the job with ``--dependency=...``
+DependencyNeverSatisfied
+  Same as *Dependency*, but that other job failed. You must cancel the job with ``scancel JOBID``.

-OpenSSH with HPN
-----------------
-The default *ssh* client and server on stallo login nodes is the *openssh* package

-To use this feature you must have a HPN patched openssh version. You can
-check if your ssh client has HPN patches by issuing:
-
-::
-
-    ssh -V
-
-if the output contains the word "hpn" followed by version and release
-then you can make use of the high performance features.
-
-Transfer can then be speed up either by disabling data encryption, AFTER
-you have been authenticated or logged into the remote host (NONE
-cipher), or by spreading the encryption load over multiple threads
-(using MT-AES-CTR cipher).

 This cipher has the highest transfer rate. Keep in mind that data after
