== Review the FAQ list ==
For frequently asked questions regarding the Carbon HPC system, review '''[[HPC/FAQ | Frequently Asked Questions]]''' to find answers.

== Compose a support request ==
If your question is not answered in the FAQ, Compose an email to our help desk, as follows:

=== Required information ===
* Choose an appropriate '''subject line''', preferably after you typed and reviewed the body of your message.
*: Do not merely hit "Reply" on a previous unrelated message - doing so might cause your request to get overlooked in a previous thread.
* Be as ''specific as possible'' in the body of your message. Include the following:
** The '''command''' you were trying to run or the menu item you chose in a graphical user interface
** The '''exact error message''' you get. Copy & Paste the message text, or take a screenshot and attach it to your mail.
** The '''directory path''' and '''file name''' you were working on, if applicable.
**: It is generally not necessary to include in your message copies of files that already reside on Carbon.

=== For issues with PBS jobs ===
For questions about PBS jobs, provide:
* the '''working directory''' of the job
* the name of the '''job file''' used
* the '''job number''' (for queued or running jobs)

=== Additions required for remote access issues ===
When you cannot log in to mega or a ''Carbon'' login node, provide the following:
* The '''hostname''' you ran the command on. It is often shown in the command prompt. (If the prompt shows <code>localhost</code> it is not specific enough – ask your local support person for help.)
* The '''hostname''' you're trying to ''reach.''
* The '''username''' you use to connect.
* The '''software''' name and version you use to connect (e.g. SSH, VNC, or a browser).
* Your '''operating system''' and version.

If you use ssh or scp, repeat your command in verbose mode by supplying the "-v" option twice:
<source lang="bash">
scp -v -v [… other options and arguments …]
ssh -v -v [… other options and arguments …]
</source>
: Copy and Paste the possibly multi-page output into your request.

=== Test directory ===
We may ask you to prepare a ''test directory'' which has to contain ''only'' files required by your application for a standalone run or a single PBS job.
This will help to diagnose your problem and confirm resolution, especially to diagnose subtle errors that are difficult to reproduce, such as where your application runs but does not fail outright.

Prepare the test directory at the same directory level as your troubled runs, and include:
* the PBS job file,
* input files,
* any local data files.
* If available, add a file with the ''expected'' (correct) output, but with a file name that's different from the one generated by the job, such as by adding <code>.ref</code>.

=== Submit ===
Before you submit a request:
* Make sure you included the '''error message''' that prompted your request.

Complete the following form submit your request:
[https://argonne.service-now.com/self_service/request_detail.do?sysparm_document_key=sc_cat_item,4e37eb5b13199f0016ff33228144b036 CNM HPC Support Request]

== Receiving support ==
When you get our support response:
* Carefully read it.
* Follow all instructions and answer all questions.
* For account- and password-related issues: it may take several hours for changes to take effect. If your initial attempt fails, wait at least that long before retrying.

== Additional considerations ==
To help us diagnose a problem:
* Read [http://www.chiark.greenend.org.uk/~sgtatham/bugs.html How to Report Bugs Effectively], by [http://www.chiark.greenend.org.uk/~sgtatham/ Simon Tatham], programmer.
* For deeper reading, consider [http://www.catb.org/~esr/faqs/smart-questions.html How To Ask Questions The Smart Way], by [http://en.wikipedia.org/wiki/Eric_S._Raymond Eric S. Raymond], open source pioneer.
