Welcome to UF Research Computing! This page is intended to help new clients get started on HiPerGator.
==Getting an account==
 
To get an account at the UF Research Computing, you need to read [http://www.hpc.ufl.edu/about/policies/account/] and then put a request in at our request page. That page is [http://www.hpc.ufl.edu/support/acctrqst/ located here].
 
  
==Login==
+
Note that new users are highly encouraged to take the [[New_user_training|New User Training]] course to familiarize themselves with using a supercomputer for research, save time, and avoid many beginner mistakes.
NOTE: If you are using UF's Visitor Wireless, you will not be able to login to our systems using SSH. You will need to arrange for access using some other network.
 
===Linux / Unix===
 
Open a terminal and run
 
ssh <YOUR_USERNAME>@gator.hpc.ufl.edu
 
where <code><YOUR_USERNAME></code> is your Research Computing username, which was sent to you when you got your Research Computing account.
 
  
The command <code>ssh <YOUR_USERNAME>@gator.hpc.ufl.edu</code> is what you would type in at a command prompt on your system.  After this, it asks you for a password, which you type in. After that, you are logged in and ready to work.  As a concrete example, if your Research Computing username is "smith", you would use the command <code>ssh smith@gator.hpc.ufl.edu</code> to log into the Research Computing.

===Windows===
+
To use HiPerGator or HiPerGator-AI you need 4 basic parts, learn about them below!
Microsoft Windows does not come with a built-in SSH client. You have to download a client from the web. We recommend the following software:

===MacOS===
+
==From Zero to HiPerGator==
For MacOS users, the connection instructions are very similar to those for Linux/Unix users.
+
===Initial Consult===
 +
If a face-to-face discussion about the group's needs is needed you can [https://www.rc.ufl.edu/get-support/walk-in-support/ meet one of the UF Research Computing Facilitators] face-to-face or virtually or [https://support.rc.ufl.edu/ submit a support request to start the conversation].  
  
''Terminal'', the terminal emulation application under MacOS is located in Applications/Utilities.
+
===HiPerGator Accounts===
 +
Group's sponsor has to be the first person to [https://www.rc.ufl.edu/access/account-request/ request a HiPerGator account] indicating that they are a new sponsor. In the process we will create their sponsored group.
  
Both [http://filezilla-project.org/download.php?type=client FileZilla] and [http://cyberduck.ch/ Cyberduck] are available for MacOS if you prefer a graphical interface for transferring files.
+
Afterwards, group members will be able to [https://www.rc.ufl.edu/access/account-request/ submit HiPerGator account requests] indicating their PI as the sponsor. Once approved, their linux accounts will be created.
  
==Running Graphical Programs==
+
===Trial Allocation===
See the [[GUI_Programs|Gui Programs]] page for information on running graphical user interface applications at UFRC.
+
We recommend that the group's sponsor [https://gravity.rc.ufl.edu/access/request-trial-allocation/ request a '''free''' trial allocation] for storage and computational resources to get the group started on HiPerGator. Group members can then use HiPerGator for the 3 month duration of the trial allocation to figure out what resources and applications they really need.
  
==Getting Help==
+
===Purchasing Resources===
If you are having problems connecting to the UFRC system, please let the UFRC Staff know by submitting a [http://support.hpc.ufl.edu Support Request].
+
After or while the group uses a trial allocation to determine the computational and storage resources it needs the group's sponsor can submit a purchase request for [https://gravity.rc.ufl.edu/access/purchase-request/hpg-hardware/ hardware (5-years)] or [https://gravity.rc.ufl.edu/access/purchase-request/hpg-service/ services (3-months to longer)] to invest into the resources to cover the group's HiPerGator use.
  
==Interactive work under Linux==
+
Some groups may have access to shared departmental allocations. In this case, instead of purchasing resources, group members can [https://support.rc.ufl.edu/ request] to be added to the departmental group to gain access to the shared resources.  
Once you are logged in to a Research Computing server, you will find yourself at a Linux command line prompt. That may be daunting at first. However, you only need to know a small subset of Linux commands to accomplish most tasks. There are many Linux "Getting Started" guides online and in print. Below are just a few possibilities. Many more are easily found via a Google search.

==Editing==
 
Editing files on the cluster can be done through a couple of different methods...

* '''vi''' - The visual editor (vi) is the traditonal Unix editor. However, it is not necessarily the most intuitive editor.  That being the case, if you are unfamiliar with it, the following tutorial may be useful.
 
** [http://www.eng.hawaii.edu/Tutor/vi.html VI Tutorial]
 
** Another resource for vi is [[vi | right here]] on our wiki.
 
** There is also a vi tutorial, '''vimtutor'''. Once logged in, simply type "<code>vimtutor</code>" at the command line to start the tutorial.
 
* '''emacs''' - Emacs is a much heavier duty editor, but again has the problem of having commands that are non-intuitive. Again, we have provided a link to a tutorial for this editor.
 
** [http://www2.lib.uchicago.edu/~keith//tcl-course/emacs-tutorial.html Emacs Tutorial]
 
* '''pico''' - While pico is not installed on the system, [[nano]] is installed, and is a pico work-a-like.
 
* '''nano''' - Nano has a good bit of on-screen help to make it easier to use.
 
 
 
===External Editors===
 
You can also use your favorite editor on your local machine and then transfer the files over to the Research Computing afterwards. One caveat to this is that with files created on Windows machines, usually contain unprintable characters which may be misinterpreted by Linux command interpreters (shells). If this happens, there is a utility called <code>dos2unix</code> that you can use to convert the text file from DOS/Windows formatting to Linux formatting.
 
 
 
==Running Jobs==
 
 
 
====Trivial Example====

Welcome to UF Research Computing! This page is intended to help new clients get started on HiPerGator.

Note that new users are highly encouraged to take the New User Training course to familiarize themselves with using a supercomputer for research, save time, and avoid many beginner mistakes.

Introduction to Using HiPerGator

To use HiPerGator or HiPerGator-AI you need 4 basic parts, learn about them below!

From Zero to HiPerGator

Initial Consult

If a face-to-face discussion about the group's needs is needed you can meet one of the UF Research Computing Facilitators face-to-face or virtually or submit a support request to start the conversation.

HiPerGator Accounts

Group's sponsor has to be the first person to request a HiPerGator account indicating that they are a new sponsor. In the process we will create their sponsored group.

Afterwards, group members will be able to submit HiPerGator account requests indicating their PI as the sponsor. Once approved, their linux accounts will be created.

Trial Allocation

We recommend that the group's sponsor request a free trial allocation for storage and computational resources to get the group started on HiPerGator. Group members can then use HiPerGator for the 3 month duration of the trial allocation to figure out what resources and applications they really need.

Purchasing Resources

After or while the group uses a trial allocation to determine the computational and storage resources it needs the group's sponsor can submit a purchase request for hardware (5-years) or services (3-months to longer) to invest into the resources to cover the group's HiPerGator use.

Some groups may have access to shared departmental allocations. In this case, instead of purchasing resources, group members can request to be added to the departmental group to gain access to the shared resources.

Some examples of departments with shared allocations include the Genetics Institute, Emerging Pathogens Institute, Statistics Department, Biostatistics Department, Center for Compressible Multiphase Turbulence (CCMT), Cognitive Aging and Memory Clinical Translational Research Program (CAMCTRP), Center for Molecular Magnetic Quantum Materials, Physics Department, and Plant Pathology Department. In addition, several research groups working on collaborative projects have shared allocations accessible to members of those projects.

At this point a group is established on HiPerGator and can continue their computational work. See below for more details on the basic use.
