===== Getting support =====
==== Trying to solve issues by yourself ====
The first thing to do when a crash occurs is to check your output files (specified in -o and -e PBS parameters). In most cases, crash details are written inside and are human-readable.

Example:\\
Your job is crashing each time you try to run it and, in your output files, you can read:
<code bash output>
[...]
Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
 File "/shared/compilers/python/2.7.5/gnu/lib/python2.7/site-packages/h5py-2.5.0-py2.7-linux-x86_64.egg/h5py/__init__.py", line 13, in <module>
   from . import _errors
ImportError: libhdf5.so.9: cannot open shared object file: No such file or directory
</code>

As you can notice above, the library libhdf5.so.9 is missing. So, the good way to solve it yourself is to wonder where is located the expected library (manifestly not in a common environment); and the good response is to load the afferent module, simply doing:
<cli>
$ module load hdf5
</cli>
This is an easy-to-understand example but it represents the vast majority of user support requests.
==== Asking help to your PI ====
After having tried to solve your problem by yourself, you should try askin help to your PI who probably have a long-term user experience with the computing resources available here and/or elsewhere.
==== Asking help to the users community of LBT's computing resources ====
Because you are part of the users community of the LBT's computing resources, a mailing-list has been created to share your issues and experience by sending an e-mail to <cluster-users@ibpc.fr>. If you are not part of this list, you should contact IBPC IT team (at <lbt-info@ibpc.fr>) to register into.

This mailing-list will also be used to inform you about computing resources evolution.
==== Asking help to the IT manager ====
All user-support requests concerning LBT's computing resources should be done sending an email at <lbt-info@ibpc.fr>.

That said, if -and only if- your request concerns the LBT's computational and storage resources (not the IBPC network and services neither desktop machines), you can contact me directly sending a well-formed email at <geoffrey.letessier@cnrs.fr>.

What I mean by "well-formed email": if possible, your email should include the following 4 pieces of information:
  * Description of your issue.
  * Is your issue reproducible? (i.e.: does it happen everytime in the same conditions?)
  * The full path of your crashing job
  * The 2 output files provided by Torque resource manager (files generated by the -e and -o PBS options in your job script), being sure you are using the script I provided [[cluster-lbt:quick_start_guide|here]]

<note> If your problem is that your job is blocked on queue, please dont kill it and provide me the output of "**checkjob -vv <job-ID>**" command</note>
